Servicing a Blade Server

This chapter contains the following sections:

Replacing a Drive

The Cisco UCS B200 M5 blade server uses an optional front storage mezzanine module that has two drive bays for hard disks or SSD drives, either 2.5-inch SAS, SATA, or NVMe. The storage mezzanine module also supports a RAID controller. If you purchased the server without the front storage mezzanine module configured as a part of the system, a pair of blanking panels may be in place. These panels should be removed before installing disk drives, but should remain in place to ensure proper cooling and ventilation if the drive bays are unused.

You can remove and install disk drives without removing the blade server from the chassis.


Caution

To avoid data loss or damage to your operating system, always perform drive service during a scheduled maintenance window.

The drives supported in this blade server come with the hot-plug drive sled attached. Empty hot-plug drive sled carriers (containing no drives) are not sold separately from the drives. A list of currently supported drives is in the Cisco UCS B200 M5 Blade Server Specification Sheet on the Cisco UCS B-Series Blade Servers Data Sheets page.

Before upgrading or adding a drive to a running blade server, check the service profile in Cisco UCS Manager and make sure the new hardware configuration will be within the parameters allowed by the service profile.


Note

See also 4K Sector Format SAS/SATA Drives Considerations.

Removing a Blade Server Drive

To remove a drive from a blade server, follow these steps:

Procedure

Step 1

Push the release button to open the ejector, and then pull the drive from its slot.

Caution 

To prevent data loss, make sure that you know the state of the system before removing a drive.
Step 2

Place the drive on an antistatic mat or antistatic foam if you are not immediately reinstalling it in another server.
Step 3

Install a drive blanking panel to maintain proper airflow and keep dust out of the drive bay if it will remain empty.

Installing a Blade Server Drive

To install a drive in a blade server, follow these steps:

Procedure

Step 1

Place the drive ejector into the open position by pushing the release button.
Step 2

Gently slide the drive into the opening in the blade server until it seats into place.

Step 3

Push the drive ejector into the closed position.

You can use Cisco UCS Manager to format and configure RAID services. For details, see the Configuration Guide for the version of Cisco UCS Manager that you are using. The configuration guides are available at the following URL: http://www.cisco.com/en/US/products/ps10281/products_installation_and_configuration_guides_list.html

If you need to move a RAID cluster, see the Cisco UCS Manager Troubleshooting Reference Guide.

4K Sector Format SAS/SATA Drives Considerations

  • You must boot 4K sector format drives in UEFI mode, not legacy mode. See the procedure in this section for setting UEFI boot mode in the boot policy.

  • Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.

  • For operating system support on 4K sector drives, see the interoperability matrix tool for your server: Hardware and Software Interoperability Matrix Tools

Setting Up UEFI Mode Booting in the UCS Manager Boot Policy

Procedure
Step 1

In the Navigation pane, click Servers.

Step 2

Expand Servers > Policies.

Step 3

Expand the node for the organization where you want to create the policy.

If the system does not include multitenancy, expand the root node.

Step 4

Right-click Boot Policies and select Create Boot Policy.

The Create Boot Policy wizard displays.
Step 5

Enter a unique name and description for the policy.

This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period). You cannot change this name after the object is saved.

Step 6

(Optional) After you make changes to the boot order, check the Reboot on Boot Order Change check box to reboot all servers that use this boot policy.

For boot policies applied to a server with a non-Cisco VIC adapter, even if the Reboot on Boot Order Change check box is not checked, when SAN devices are added, deleted, or their order is changed, the server always reboots when boot policy changes are saved.

Step 7

(Optional) If desired, check the Enforce vNIC/vHBA/iSCSI Name check box.

  • If checked, Cisco UCS Manager displays a configuration error and reports whether one or more of the vNICs, vHBAs, or iSCSI vNICs listed in the Boot Order table match the server configuration in the service profile.

  • If not checked, Cisco UCS Manager uses the vNICs or vHBAs (as appropriate for the boot option) from the service profile.

Step 8

In the Boot Mode field, choose the UEFI radio button.

Step 9

Check the Boot Security check box if you want to enable UEFI boot security.
Step 10

Configure one or more of the following boot options for the boot policy and set their boot order:

  • Local Devices boot—To boot from local devices, such as local disks on the server, virtual media, or remote virtual disks, continue with Configuring a Local Disk Boot for a Boot Policy in the Cisco UCS Manager Server Management Guide for your release.

  • SAN boot—To boot from an operating system image on the SAN, continue with Configuring a SAN Boot for a Boot Policy in the Cisco UCS Manager Server Management Guide for your release.

You can specify a primary and a secondary SAN boot. If the primary boot fails, the server attempts to boot from the secondary

Removing a Blade Server Cover

To remove the cover of the blade server, follow these steps:

Procedure

Step 1

Press and hold the button down as shown in the figure below.

Step 2

While holding the back end of the cover, pull the cover back and then up.

Figure 1. Removing the Cover of the Blade Server

Note

When the front mezzanine storage module is installed, the USB connector is underneath it. Use the small cutout opening in the storage module to visually determine the location of the USB connector when you need to insert a USB drive. When the NVIDIA GPU is installed in the front mezzanine slot, you cannot see the USB connector.

Diagnostics Button and LEDs

At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs, and rear mezzanine modules, and any failure notifications are sent to Cisco UCS Manager. You can view these notifications in the Cisco UCS Manager System Error Log or in the output of the show tech-support command. If errors are found, an amber diagnostic LED also lights up next to the failed component. During run time, the blade BIOS and component drivers monitor for hardware faults and will light up the amber diagnostic LED as needed.

LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to 10 minutes. Pressing the LED diagnostics button on the motherboard causes the LEDs that currently show a component fault to light for up to 30 seconds for easier component identification. LED fault values are reset when the blade is reinserted into the chassis and booted, and the process begins from its start.

If DIMM insertion errors are detected, they may cause the blade discovery process to fail and errors will be reported in the server POST information, which is viewable using the UCS Manager GUI or CLI. DIMMs must be populated according to specific rules. The rules depend on the blade server model. Refer to the documentation for a specific blade server for those rules.

Faults on the DIMMs or rear mezzanine modules also cause the server health LED to light solid amber for minor error conditions or blinking amber for critical error conditions.

Installing the Front Mezzanine Storage Module

The Cisco UCS B200 M5 blade server uses an optional front mezzanine storage module that can provide support for two drive bays and RAID controller or NVMe-based PCIe SSD support functionality.


Note

There are restrictions against using the front mezzanine storage module with certain CPUs because of heat concerns. See CPU Configuration Rules.

To install the front mezzanine storage module, follow these steps:

Procedure

Step 1

Remove the connectors’ protective covers from both the front mezzanine storage module and the motherboard.
Step 2

Place the storage module over the front mezzanine connector and the two standoff posts on the motherboard at the front of the servers.

Step 3

Press down on the drive bay cage where it is labeled "Press Here to Install" until the storage module clicks into place.

Figure 3. Front Mezzanine Storage Module
Step 4

Using a Phillips-head screwdriver, tighten the four screws to secure the storage module. The locations of the screws are labeled "Secure Here."

Replacing the SuperCap Module

The SuperCap module is a battery bank which connects to the front mezzanine storage module board and provides power to the RAID controller if facility power is interrupted.

To replace the SuperCap module, use the following topics:

Removing the SuperCap Module

The SuperCap module sits in a plastic tray. The module connects to the board through a ribbon cable with one connector to the module and one connector to the board. The SuperCap replacement PID (UCSB-MRAID-SC=) contains the module only, so you must leave the ribbon cable in place on the board.


Caution

When disconnecting the SuperCap module, disconnect the ribbon cable from the module only. Do not disconnect the cable from the board. The board connection and the tape that secures the cable must remain connected and undamaged.

To replace the SuperCap module, follow these steps:

Procedure

Step 1

Grasp the cable connector at the SuperCap module and gently pull to disconnect the cable from the SuperCap module.

Do not grasp the cable itself, the tape, or the board connector.
Figure 4. Disconnecting the SuperCap Cable from the Module, Not the Board
Step 2

Before removing the SuperCap module, note its orientation in the tray.

When correctly oriented, the connector is on the bottom half of the module and faces the cable. You will need to install the new SuperCap module with the same orientation.

Step 3

Grasp the sides of the SuperCap module, but not the connector, and lift the SuperCap module out of the tray.

Figure 5. Removing the SuperCap Module

You might feel some resistance because the tray is curved to secure the module.

Installing the SuperCap Module

To install a SuperCap module (UCSB-MRAID-SC=), use the following steps:

Procedure

Step 1

Orient the SuperCap module correctly, as shown (1).

When correctly oriented:

  • The connector is on the bottom half of the module facing the cable.

  • The connector will fit into the rectangular notch in the tray. This notch is specifically designed to accept the SuperCap module connector.

Caution 

Make sure the SuperCap module is properly oriented before proceeding. If the module is installed incorrectly, the ribbon cable can get snagged or damaged.

Step 2

When the module is correctly oriented, lower the module and press down until it clips into the tray.

You might feel some resistance while the module passes the curved clips at the top of the tray.

Figure 6. Orienting and Installing the SuperCap Module
Step 3

When the module is seated in the tray, reconnect the cable (2):

  1. Grasp the cable connector and verify that the pins and sockets on the cable connector and module connector are correctly aligned.

  2. When the cable connector and module connector are properly aligned, plug the cable into the SuperCap module.

What to do next

Reinstall the blade server. Go to Installing a Blade Server.

Replacing CPUs and Heatsinks

This topic describes the configuration rules and procedure for replacing CPUs and heatsinks.

Special Information For Upgrades to Second Generation Intel Xeon Scalable Processors


Caution

You must upgrade your server firmware to the required minimum level before you upgrade to the Second Generation Intel Xeon Scalable processors that are supported in this server. Older firmware versions cannot recognize the new CPUs and this would result in a non-bootable server.

The minimum software and firmware versions required for this server to support Second Generation Intel Xeon Scalable processors are as follows:

Table 1. Minimum Requirements For Second Generation Intel Xeon Scalable Processors

Software or Firmware

Minimum Version

Cisco UCS Manager

4.0(4)

Server Cisco IMC

4.0(4)

Server BIOS

4.0(4)

Do one of the following actions:

  • If your server's firmware and Cisco UCS Manager software are already at the required minimums shown above (or later), you can replace the CPU hardware by using the procedure in this section.

  • If your server's firmware and Cisco UCS Manager software are earlier than the required levels, use the instructions in the Cisco UCS B-Series M5 Servers Upgrade Guide For Next Gen Intel Xeon Processors to upgrade your software. After you upgrade the software, return to this section as directed to replace the CPU hardware.

CPU Configuration Rules

This server has two CPU sockets on the motherboard. Each CPU supports six DIMM channels (12 DIMM slots). See Memory Population Guidelines.

  • The server can operate with one CPU or two identical CPUs installed.

  • The minimum configuration is at least CPU 1 installed. Install CPU 1 first, and then CPU 2.

    The following restrictions apply when using a single-CPU configuration:

    • Any unused CPU socket must have the protective dust cover from the factory in place.

    • The maximum number of DIMMs is 12 (only CPU 1 channels A, B, C, D, E, F).

    • The rear mezzanine slot is unavailable.

  • For Intel Xeon Scalable processors (first generation): The maximum combined memory allowed in the 12 DIMM slots controlled by any one CPU is 768 GB. To populate the 12 DIMM slots with more than 768 GB of combined memory, you must use a high-memory CPU that has a PID that ends with an "M", for example, UCS-CPU-6134M.

  • For Second Generation Intel Xeon Scalable processors: These Second Generation CPUs have three memory tiers. These rules apply on a per-socket basis:

    • If the CPU socket has up to 1 TB of memory installed, a CPU with no suffix can be used (for example, Gold 6240).

    • If the CPU socket has 1 TB or more (up to 2 TB) of memory installed, you must use a CPU with an M suffix (for example, Platinum 8276M).

    • If the CPU socket has 2 TB or more (up to 4.5 TB) of memory installed, you must use a CPU with an L suffix (for example, Platinum 8270L).


Caution
In the following table, systems configured with the processors shown must adhere to the ambient inlet temperature thresholds specified. If not, a fan fault or executing workloads with extensive use of heavy instructions sets such as Intel® Advanced Vector Extensions 512 (Intel® AVX-512) may assert thermal and/or performance faults with an associated event recorded in the System Event Log (SEL). The following table lists ambient temperature limitations below 35° C (95° F) and configuration restrictions to ensure proper cooling and avoid excessive processor throttling, which may impact system performance.

Tools Required for CPU Replacement

You need the following tools and equipment for this procedure:

  • T-30 Torx driver—Supplied with replacement CPU.

  • #1 flat-head screwdriver—Supplied with replacement CPU.

  • CPU assembly tool—Supplied with replacement CPU. Can be ordered separately as Cisco PID UCS-CPUAT=.

  • Heatsink cleaning kit—Supplied with replacement CPU. Can be ordered separately as Cisco PID UCSX-HSCK=.

    One cleaning kit can clean up to four CPUs.

  • Thermal interface material (TIM)—Syringe supplied with replacement CPU. Use only if you are reusing your existing heatsink (new heatsinks have pre-applied TIM). Can be ordered separately as Cisco PID UCS-CPU-TIM=.

    One TIM kit covers one CPU.

Replacing a CPU and Heatsink


Caution

CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins. The CPUs must be installed with heatsinks and thermal interface material to ensure cooling. Failure to install a CPU correctly might result in damage to the server.

Procedure

Step 1

Remove the existing CPU/heatsink assembly from the server.

  1. Decommission and power off the server.

  2. Slide the server out the front of the chassis.

  3. Remove the top cover from the server as described in Removing a Blade Server Cover.

  4. Use the T-30 Torx driver that is supplied with the replacement CPU to loosen the four captive nuts that secure the heatsink with the attached CPU assembly to the motherboard standoffs.

    Note 
    Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1.

  5. Lift straight up on the CPU/heatsink assembly and set it heatsink-down on an antistatic surface.

    Note 

    Make sure to hold the heatsink along the fin edges and not the fin walls to prevent damaging the heatsink.

  2. Pinch inward on the CPU-carrier inner-latch that is nearest the TIM breaker slot and then push up to disengage the clip from its slot in the heatsink corner.

  3. Insert the blade of a #1 flat-head screwdriver into the slot marked TIM BREAKER.

  4. Gently rotate the screwdriver to lift the CPU heat spreader until the TIM on the heatsink separates from the CPU.

    Note 

    Use caution to avoid damaging the heatsink surface. Do not allow the screwdriver tip to touch or damage the green CPU substrate.

  5. Pinch the CPU-carrier inner-latch at the corner opposite the TIM breaker and push up to disengage the clip from its slot in the heatsink corner.

  6. On the remaining two corners of the CPU carrier, gently pry outward on the outer-latches and then lift the CPU-assembly from the heatsink.

    Note 
    Handle the CPU-assembly by the plastic carrier only. Do not touch the CPU surface. Do not separate the CPU from the carrier.
Step 3

The new CPU assembly is shipped on a CPU assembly tool. Take the new CPU assembly and CPU assembly tool out of the carton.

Caution 

When CPUs greater than 165 W are installed in the server, you cannot install the front mezzanine storage module because of heat concerns. There are other CPUs that require a reduction in server operating temperature (air inlet temperature). See CPU Configuration Rules

.

If the CPU assembly and CPU assembly tool become separated, note the alignment features shown in the following figure for the correct orientation. The pin 1 triangle on the CPU carrier must be aligned with the angled corner on the CPU assembly tool.

Caution 

CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins.

Step 4

Apply new TIM.

Note 
The heatsink must have new TIM on the heatsink-to-CPU surface to ensure proper cooling and performance.

  • If you are installing a new heatsink, it is shipped with a pre-applied pad of TIM. Go to step 5.

  • If you are reusing a heatsink, you must remove the old TIM from the heatsink and then apply new TIM to the CPU surface from the supplied syringe. Continue with step a below.

  1. Apply the Bottle #1 cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=), as well as the spare CPU package, to the old TIM on the heatsink and let it soak for a least 15 seconds.

  2. Wipe all of the TIM off the heatsink using the soft cloth that is included with the heatsink cleaning kit. Be careful to avoid scratching the heatsink surface.

  3. Completely clean the bottom surface of the heatsink using Bottle #2 to prepare the heatsink for installation.

  4. Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 1.5 cubic centimeters (1.5 ml) of thermal interface material to the top of the CPU. Use the pattern shown in the following figure to ensure even coverage.

    Figure 10. Thermal Interface Material Application Pattern
    Caution 

    Use only the correct heatsink for your CPU. CPU 1 uses heatsink UCSB-HS-M5-F and CPU 2 uses heatsink UCSB-HS-M5-R.

Step 5

With the CPU assembly on the CPU assembly tool, set the heatsink onto the CPU assembly.

  1. Place the heatsink onto the CPU by aligning the Pin 1 corner of the heatsink with the Pin 1 tab of the CPU carrier for the correct orientation.

  2. Push down gently until you hear the corner latches of the CPU carrier click onto the heatsink corners.

  3. Inspect all four latches to verify they are fully engaged.

Caution 

In the following step, use extreme care to avoid touching or damaging the CPU contacts or the CPU socket pins.
Step 6

Install the CPU/heatsink assembly to the server.

  1. Lift the heatsink with attached CPU assembly from the CPU assembly tool.

    Note 

    Make sure to hold the heatsink along the fin edges and not the fin walls to prevent damaging the heatsink.

  2. Align the CPU with heatsink over the CPU socket on the motherboard, as shown in the following figure.

    Note the alignment features. The pin 1 angled corner on the heatsink must align with the pin 1 angled corner on the CPU socket. The CPU socket alignment pins must properly align with the slots on the CPU carrier and heatsink. Take note of the two different sizes of the alignment pins.

  4. Use the T-30 Torx driver that is supplied with the replacement CPU to tighten the four captive nuts that secure the heatsink to the motherboard standoffs.

    Caution 
    Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is installed. Tighten the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The captive nuts must be fully tightened so that the leaf springs on the CPU socket lie flat.

  5. Replace the top cover to the server.

  6. Replace the server in the chassis.

  7. Wait for Cisco UCS Manager to complete its automatic discovery of the server.

Additional CPU-Related Parts to Order with CPU RMA

When a return material authorization (RMA) of the CPU occurs for a Cisco UCS B-Series server, additional parts might not be included with the CPU spare bill of materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.


Note

The following items apply to CPU replacement scenarios. If you are replacing a system chassis and moving existing CPUs to the new chassis, you do not have to separate the heatsink from the CPU. See Additional CPU-Related Parts to Order with RMA Replacement Blade Server.

  • Scenario 1—You are reusing the existing heatsinks:

    • Heat sink cleaning kit (UCSX-HSCK=)

      One cleaning kit can clean up to four CPUs.

    • Thermal interface material (TIM) kit for M5 servers (UCS-CPU-TIM=)

      One TIM kit covers one CPU.

  • Scenario 2—You are replacing the existing heatsinks:

    (New heatsinks have a pre-applied pad of TIM.)

    • Heatsink for CPU 1: UCSB-HS-M5-F=

    • Heatsink for CPU 2: UCSB-HS-M5-R=

    • Heatsink cleaning kit (UCSX-HSCK=)

      One cleaning kit can clean up to four CPUs.

  • Scenario 3—You have a damaged CPU carrier (the plastic frame around the CPU):

    • CPU Carrier: UCS-M5-CPU-CAR=

    • #1 flat-head screwdriver (for separating the CPU from the heatsink)

    • Heatsink cleaning kit (UCSX-HSCK=)

      One cleaning kit can clean up to four CPUs.

    • Thermal interface material (TIM) kit for M5 servers (UCS-CPU-TIM=)

      One TIM kit covers one CPU.

A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old TIM and the other to prepare the surface of the heatsink.

New heatsink spares come with a pre-applied pad of TIM. It is important to clean any old TIM off of the CPU surface prior to installing the heatsinks. Therefore, even when you are ordering new heatsinks, you must order the heatsink cleaning kit.

Additional CPU-Related Parts to Order with RMA Replacement Blade Server

When a return material authorization (RMA) of the blade server is done, you move existing CPUs to the new server.


Note

Unlike previous generation CPUs, the M5 server CPUs do not require you to separate the heatsink from the CPU when you move the CPU-heatsink assembly. Therefore, no additional heatsink cleaning kit or thermal-interface material items are required.

  • The only tool required for moving a CPU/heatsink assembly is a T-30 Torx driver.

To move a CPU to a new blade server, use the procedure in Moving an M5 Generation CPU.

Moving an M5 Generation CPU

Tool required for this procedure: T-30 Torx driver


Caution

When you receive a replacement server for an RMA, it includes dust covers on all CPU sockets. These covers protect the socket pins from damage during shipping. You must transfer these covers to the system that you are returning, as described in this procedure.

Procedure

Step 1

When moving an M5 CPU to a new blade server, you do not have to separate the heatsink from the CPU. Perform the following steps:

  1. Use a T-30 Torx driver to loosen the four captive nuts that secure the assembly to the board standoffs.

    Note 
    Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1.

  2. Lift straight up on the CPU/heatsink assembly to remove it from the board.

  3. Set the CPUs with heatsinks aside on an anti-static surface.

    -

  2. With the wording on the dust cover facing up, set it in place over the CPU socket in the system that you are returning. Make sure that all alignment posts on the socket plate align with the cutouts on the cover.

    Caution 

    In the next step, do not press down anywhere on the dust cover except the two points described. Pressing elsewhere might damage the socket pins.

  3. Press down on the two circular markings next to the word "INSTALL" that are closest to the two threaded posts (see the following figure). Press until you feel and hear a click.

    Note 

    You must press until you feel and hear a click to ensure that the dust covers do not come loose during shipping.

    -

    Press down on the two circular marks next to the word INSTALL.

    -
Step 3

Install the CPUs to the new system:

  1. On the new board, align the assembly over the CPU socket, as shown below.

    Note the alignment features. The pin 1 angled corner on the heatsink must align with the pin 1 angled corner on the CPU socket. The CPU-socket posts must align with the guide-holes in the assembly.

    Note 

    Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is lowered. Tighten the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The captive nuts must be fully tightened so that the leaf springs on the CPU socket lie flat.

Replacing Memory DIMMs

The DIMMs that this blade server supports are updated frequently. A list of supported and available DIMMs is in Cisco UCS B200 M5 Specification Sheet.

Do not use any DIMMs other than those listed in the specification sheet. Doing so may irreparably damage the server and result in down time.

Memory Population Guidelines

This blade server contains 24 DIMM slots—12 per CPU.


Caution

Only Cisco memory is supported. Third-party DIMMs are not tested or supported.


Note

When using 256 GB DDR DIMMs (UCS-ML-256G8RT-H) in this server, the blade-level power capping must be set to 550 W. For information about blade-level power capping, see the Power Capping and Power Management chapter in the Cisco UCS Manager Server Management Guide for your release: Cisco UCS Manager Configuration Guides.

  • Each set of 12 DIMMs is arranged into six channels, where each channel has two DIMMs. Each DIMM slot is numbered 1 or 2, and each DIMM slot 1 is blue and each DIMM slot 2 is black. Each channel is identified by a letter:

    • Channels A, B, C, D, E, and F are for CPU 1.

    • Channels G, H, J, K, L, and M are for CPU 2.

  • The maximum combined memory allowed in the 12 DIMM slots is 768 GB. To populate the 12 DIMM slots with more than 768 GB of combined memory, use a CPU with a SKU that ends with an "M", for example, UCS-CPU-6134M.

  • The following figure shows how DIMMs and channels are physically laid out and numbered.

    Figure 16. Physical Location of DIMM Slots

    1

    DIMM slots for CPU 1

    2

    DIMM slots for CPU 2

  • A DIMM channel has either one or two DIMMs. For those channels with one DIMM, a DIMM blank must be installed. A slot cannot be empty. For installation instructions, see Installing a DIMM or DIMM Blank.

  • For optimal performance, populate DIMMs in the order shown in the following table, depending on the number of CPUs and the number of DIMMs per CPU. If your server has two CPUs, balance DIMMs evenly across the two CPUs as shown in the table.


    Note

    The table below lists recommended configurations. Using 5, 7, 9, 10, or 11 DIMMs per CPU is not recommended.

Installing a DIMM or DIMM Blank

To install a DIMM or a DIMM blank (UCS-DIMM-BLK=) into a slot on the blade server, follow these steps.

Procedure

Step 1

Open both DIMM connector latches.
Step 2

Press evenly on both ends of the DIMM until it clicks into place in its slot.

Note 

Ensure that the notch in the DIMM aligns with the slot. If the notch is misaligned, it is possible to damage the DIMM, the slot, or both.

Step 3

Press the DIMM connector latches inward slightly to seat them fully.
Step 4

Populate all slots with a DIMM or DIMM blank. A slot cannot be empty.

Figure 17. Installing Memory

Memory Performance

When considering the memory configuration of the blade server, there are several things to consider. For example:

  • When mixing DIMMs of different densities (capacities), the highest density DIMM goes in slot 1 then in descending density.

  • Besides DIMM population and choice, the selected CPU(s) can have some effect on performance.

Memory Mirroring and RAS

The Intel CPUs within the blade server support memory mirroring only when an even number of channels are populated with DIMMs. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.

Replacing Intel Optane DC Persistent Memory Modules

This topic contains information for replacing Intel Optane Data Center Persistent memory modules (DCPMMs), including population rules. DCPMMs have the same form-factor as DDR4 DIMMs and they install to DIMM slots.


Note

Intel Optane DC persistent memory modules require Second Generation Intel Xeon Scalable processors. You must upgrade the server firmware and BIOS to version 4.0(4) or later and install the supported Second Generation Intel Xeon Scalable processors before installing DCPMMs.


Caution

DCPMMs and their sockets are fragile and must be handled with care to avoid damage during installation.

Note

To ensure the best server performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace DCPMMs.

DCPMMs can be configured to operate in one of three modes:

  • Memory Mode (default): The module operates as 100% memory module. Data is volatile and DRAM acts as a cache for DCPMMs. This is the factory default mode.

  • App Direct Mode: The module operates as a solid-state disk storage device. Data is saved and is non-volatile.

  • Mixed Mode (25% Memory Mode + 75% App Direct): The module operates with 25% capacity used as volatile memory and 75% capacity used as non-volatile storage.

Intel Optane DC Persistent Memory Module Population Rules and Performance Guidelines

This topic describes the rules and guidelines for maximum memory performance when using Intel Optane DC persistent memory modules (DCPMMs) with DDR4 DRAM DIMMs.

DIMM Slot Numbering

The following figure shows the numbering of the DIMM slots on the server motherboard.

Figure 18. DIMM Slot Numbering

Configuration Rules

Observe the following rules and guidelines:

  • To use DCPMMs in this server, two CPUs must be installed.

  • Intel Optane DC persistent memory modules require Second Generation Intel Xeon Scalable processors. You must upgrade the server firmware and BIOS to version 4.0(4) or later and then install the supported Second Generation Intel Xeon Scalable processors before installing DCPMMs.

  • When using DCPMMs in a server:

    • The DDR4 DIMMs installed in the server must all be the same size.

    • The DCPMMs installed in the server must all be the same size and must have the same SKU.

  • The DCPMMs run at 2666 MHz. If you have 2933 MHz RDIMMs or LRDIMMs in the server and you add DCPMMs, the main memory speed clocks down to 2666 MHz to match the speed of the DCPMMs.

  • Each DCPMM draws 18 W sustained, with a 20 W peak.

  • The following table shows supported DCPMM configurations for this server. Fill the DIMM slots for CPU 1 and CPU2 as shown, depending on which DCPMM:DRAM ratio you want to populate.

Figure 19. Supported DCPMM Configurations for Dual-CPU Configurations

Installing Intel Optane DC Persistent Memory Modules


Note

DCPMM configuration is always applied to all DCPMMs in a region, including a replacement DCPMM. You cannot provision a specific replacement DCPMM on a preconfigured server.

Understand which mode your DCPMM is operating in. App Direct mode has some additional considerations in this procedure.

Caution

Replacing a DCPMM in App-Direct mode requires all data to be wiped from the DCPMM. Make sure to backup or offload data before attemping this procedure.

Procedure

Step 1

For App Direct mode, backup the existing data stored in all Optane DIMMs to some other storage.
Step 2

For App Direct mode, remove the Persistent Memory policy which will remove goals and namespaces automatically from all Optane DIMMs.

Step 3

Remove an existing DCPMM:

  1. Decommission and power off the server.

  2. Remove the top cover from the server as described in Removing a Blade Server Cover.

  3. Slide the server out the front of the chassis.

    Caution 

    If you are moving DCPMMs with active data (persistent memory) from one server to another as in an RMA situation, each DCPMM must be installed to the identical position in the new server. Note the positions of each DCPMM or temporarily label them when removing them from the old server.

  4. Locate the DCPMM that you are removing, and then open the ejector levers at each end of its DIMM slot.
Step 4

Install a new DCPMM:

Note 

Before installing DCPMMs, see the population rules for this server: Intel Optane DC Persistent Memory Module Population Rules and Performance Guidelines.

  1. Align the new DCPMM with the empty slot on the motherboard. Use the alignment feature in the DIMM slot to correctly orient the DCPMM.

  2. Push down evenly on the top corners of the DCPMM until it is fully seated and the ejector levers on both ends lock into place.

  3. Replace the top cover to the server.

  4. Replace the server in the chassis.

  5. Wait for Cisco UCS Manager to complete its automatic discovery of the server.

Step 5

Perform post-installation actions:

Note 

If your Persistent Memory policy is Host Controlled, you must perform the following actions from the OS side.

  • If the existing configuration is in 100% Memory mode, and the new DCPMM is also in 100% Memory mode (the factory default), the only action is to ensure that all DCPMMs are at the latest, matching firmware level.

  • If the existing configuration is fully or partly in App-Direct mode and new DCPMM is also in App-Direct mode, then ensure that all DCPMMs are are at the latest matching firmware level and also re-provision the DCPMMs by creating a new goal. Goals are automatically deleted when the persistent memory policy is deleted, so you cannot edit or explicitly delete the existing goal before creating the new one.

    • For App Direct mode, reapply the Persistent Memory policy.

    • For App Direct mode, restore all the offloaded data to the DCPMMs.

    You can configure a DCPMM goal through the server's BIOS Setup Utility, Cisco IMC, Cisco UCS Manager, or OS-related utilities.

  • If the existing configuration and the new DCPMM are in different modes, then ensure that all DCPMMs are at the latest matching firmware level and also re-provision the DCPMMs by creating a new goal. Goals are automatically deleted when the persistent memory policy is deleted, so you cannot edit or explicitly delete the existing goal before creating the new one.

There are a number of tools for configuring goals, regions, and namespaces.

Server BIOS Setup Utility Menu for DCPMM


Caution

Potential data loss: If you change the mode of a currently installed DCPMM from App Direct or Mixed Mode to Memory Mode, any data in persistent memory is deleted.

DCPMMs can be configured by using the server's BIOS Setup Utility, Cisco IMC, Cisco UCS Manager, or OS-related utilities.

The server BIOS Setup Utility includes menus for DCPMMs. They can be used to view or configure DCPMM regions, goals, and namespaces, and to update DCPMM firmware.

To open the BIOS Setup Utility, press F2 when prompted during a system boot.

The DCPMM menu is on the Advanced tab of the utility:

Advanced > Intel Optane DC Persistent Memory Configuration

From this tab, you can access other menu items:

  • DIMMs: Displays the installed DCPMMs. From this page, you can update DCPMM firmware and configure other DCPMM parameters.

    • Monitor health

    • Update firmware

    • Configure security

      You can enable security mode and set a password so that the DCPMM configuration is locked. When you set a password, it applies to all installed DCPMMs. Security mode is disabled by default.

    • Configure data policy

  • Regions: Displays regions and their persistent memory types. When using App Direct mode with interleaving, the number of regions is equal to the number of CPU sockets in the server. When using App Direct mode without interleaving, the number of regions is equal to the number of DCPMMs in the server.

    From the Regions page, you can configure memory goals that tell the DCPMM how to allocate resources.

    • Create goal config

  • Namespaces: Displays namespaces and allows you to create or delete them when persistent memory is used. Namespaces can also be created when creating goals. A namespace provisioning of persistent memory applies only to the selected region.

    Existing namespace attributes such as the size cannot be modified. You can only add or delete namespaces.

  • Total capacity: Displays the total resource allocation across the server.

Updating the DCPMM Firmware Using the BIOS Setup Utility

You can update the DCPMM firmware from the BIOS Setup Utility if you know the path to the .bin files. The firmware update is applied to all installed DCPMMs.

  1. Navigate to Advanced > Intel Optane DC Persistent Memory Configuration > DIMMs > Update firmware

  2. Under File:, provide the file path to the .bin file.

  3. Select Update.

Figure 27. Installing the NVIDIA P6 GPU in the Rear Mezzanine Slot

Enabling the Trusted Platform Module

The Trusted Platform Module (TPM) is a component that can securely store artifacts used to authenticate the server. These artifacts can include passwords, certificates, or encryption keys. A TPM can also be used to store platform measurements that help ensure that the platform remains trustworthy. Authentication (ensuring that the platform can prove that it is what it claims to be) and attestation (a process helping to prove that a platform is trustworthy and has not been breached) are necessary steps to ensure safer computing in all environments. It is a requirement for the Intel Trusted Execution Technology (TXT) security feature, which must be enabled in the BIOS settings for a server equipped with a TPM.

The Cisco UCS B200 M5 supports two options of TPM:

  • The TPM 1.2.

  • The TPM 2.0, UCSX-TPM2-002B(=), which is compliant with Federal Information Processing (FIPS) Standard 140-2. FIPS support has existed, but FIPS 140-2 is now supported.

Procedure

Step 1

Install the TPM hardware.

  1. Decommission, power off, and remove the blade server from the chassis.

  2. Remove the top cover from the server as described in Removing a Blade Server Cover.

  3. Install the TPM to the TPM socket on the server motherboard and secure it using the one-way screw that is provided. See the figure below for the location of the TPM socket.

  4. Return the blade server to the chassis and allow it to be automatically reacknowledged, reassociated, and recommissioned.

  5. Continue with enabling TPM support in the server BIOS in the next step.

Figure 28. TPM Socket Location

1

Front of server

2

TPM socket on motherboard

Step 2

Enable TPM Support in the BIOS.

  1. In the Cisco UCS Manager Navigation pane, click the Servers tab.

  2. On the Servers tab, expand Servers > Policies.

  3. Expand the node for the organization where you want to configure the TPM.

  4. Expand BIOS Policies and select the BIOS policy for which you want to configure the TPM.

  5. In the Work pane, click the Advanced tab.

  6. Click the Trusted Platform sub-tab.

  7. To enable TPM support, click Enable or Platform Default.

  8. Click Save Changes.

  9. Continue with the next step.

Step 3

Enable TXT Support in the BIOS Policy, which is supported on both TPMs.

Follow the procedures in the Cisco UCS Manager Configuration Guide for the release that is running on the server.

Removing the Trusted Platform Module (TPM)

The TPM module is attached to the printed circuit board assembly (PCBA). You must disconnect the TPM module from the PCBA before recycling the PCBA. The TPM module is secured to a threaded standoff by a tamper-resistant screw. If you do not have the correct tool for the screw, you can use a pair of pliers to remove the screw.

Before you begin


Note

For Recyclers Only! This procedure is not a standard field-service option. This procedure is for recyclers who will be reclaiming the electronics for proper disposal to comply with local eco design and e-waste regulations.


Caution

Removing the TPM results in the TPM becoming unusable. Do not use this procedure to swap a TPM to a different blade server because the part is not guaranteed to be re-installable after it is removed from the original blade server. Use this procedure only to remove the TPM for recycling or destruction.

To remove the Trusted Platform Module (TPM), the following requirements must be met for the server:

  • It must be disconnected from facility power.

  • It must removed from the equipment rack.

  • The top cover must be removed. If the top cover is not removed, see Removing a Blade Server Cover.

Procedure

Step 1

Locate the TPM module.

The following illustration shows the location of the TPM module's screw.

Figure 29. Screw Location for Removing the TPM Module
Step 2

Using the pliers, grip the head of the screw and turn it counter clockwise until the screw releases.
Step 3

Remove the TPM module and dispose of it properly.

What to do next

Remove and dispose of the PCB Assembly. See Recycling the PCB Assembly (PCBA).

Mini-Storage Module

The server has a mini-storage module option that plugs into a motherboard socket to provide additional internal storage. The mini-storage module can be one of the following types:

  • An SD card module that supports up to two SD cards.

  • An M.2 SSD module that supports up to two SATA M.2 SSDs.


Note

The Cisco IMC firmware does not include an out-of-band management interface for the M.2 drives installed in the M.2 version of this mini-storage module (UCS-MSTOR-M2). The M.2 drives are not listed in Cisco IMC inventory, nor can they be managed by Cisco IMC. This is expected behavior.

Replacing the Mini-Storage Module Carrier

This topic describes how to remove and replace a mini-storage module carrier. The carrier has one media socket on its top and one socket on its underside. Use the following procedure for any type of mini-storage module carrier (SD card or M.2 SSD).

Procedure

Step 1

Remove the carrier from the server:

  1. Press out on the securing clips to disengage the module from the server board socket.

  2. Pull straight up on the storage module to remove it.

    Figure 30. Removing the Mini-Storage Module Carrier
Step 2

Install a carrier to the server:

  1. Align the two holes on the carrier with the holder pins.

  2. Push the carrier into the holder on both ends, making sure the securing clips snap in. Push on the four corners of the carrier to fully seat it.

    Figure 31. Installing the Mini-Storage Module Carrier

Replacing an M.2 SSD

This task describes how to remove an M.2 SSD from the mini-storage module carrier.

Population Rules For Mini-Storage M.2 SSDs

  • You can use one or two M.2 SSDs in the carrier.

  • M.2 socket 1 is on the top side of the carrier; M.2 socket 2 is on the underside of the carrier (the same side as the carrier's connector to the server board socket).

  • Dual SATA M.2 SSDs can be configured in a RAID 1 array through the BIOS Setup Utility's embedded SATA RAID interface. See Embedded SATA RAID Controller.


    Note

    The M.2 SSDs cannot be controlled by a hardware RAID controller card.


    Note

    The embedded SATA RAID controller requires that the server is set to boot in UEFI mode rather than Legacy mode.

Procedure

Step 1

Remove an M.2 SSD from the carrier:

  1. Using a #1 Phillips-head screwdriver, loosen the single screw that secures the M.2 SSD to the mini-storage module carrier.

  2. Pull the M.2 SSD from the socket on the carrier.
Step 2

Install an M.2 SSD:

  1. Align the gold fingers on the M.2 card with the module connector on the top of the M.2 mini-storage module, and then fully push the M.2 card into the module connector.

  2. Using a #1 Phillips-head screwdriver, install the single screw to secure the M.2 card to the M.2 mini-storage module.

    Figure 32. Installing M.2 SSDs to the Carrier

Embedded SATA RAID Controller

The server includes an embedded SATA MegaRAID controller that can be used to control internal SATA M.2 drives. This controller supports RAID levels 0 and 1.


Note
The VMware ESX/ESXi operating system is not supported with the embedded SATA MegaRAID controller in SW RAID mode. You can use VMWare in AHCI mode.

Note

The Microsoft Windows Server 2016 Hyper-V hypervisor is supported for use with the embedded MegaRAID controller in SW RAID mode, but all other hyperviors are not supported. All Hypervisors are supported in AHCI mode.


Note

You cannot control the M.2 SATA SSDs in the server with a HW RAID controller.

Embedded SATA RAID Requirements

The embedded SATA RAID controller requires the following items:

  • The embedded SATA RAID controller must be enabled in Cisco UCS Manager.

  • M.2 mini-storage module with two SATA M.2 SSDs.

  • The software RAID controller requires UEFI boot mode; legacy boot mode is not supported.

  • (Optional) LSI MegaSR drivers for Windows or Linux.

  • If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set to LSI SW RAID mode.

Embedded SATA RAID Controller Considerations

Note the following considerations:

  • The default setting for this embedded controller hub is SATA RAID 0 and 1 support for two M.2 SATA drives. The hub is divided into two SATA controllers that have different functions. See Embedded SATA RAID: Two SATA Controllers.

  • When you order the server with this embedded controller, the controller is enabled. Instructions for enabling the controller are included for the case in which a server is reset to defaults. See Enabling SATA Mode.

  • The required drivers for this controller are already installed and ready to use. However, if you will use this controller with Windows or Linux, you must download and install additional drivers for those operating systems. See Installing LSI MegaSR Drivers For Windows and Linux.

Embedded SATA RAID: Two SATA Controllers

The embedded RAID platform controller hub (PCH) is split into two controllers: primary SATA (pSATA) and secondary SATA (sSATA). These two controllers are seen as separate RAID controllers in UCS Manager.

  • The primary pSATA controller is disabled.

  • The secondary sSATA controller controls two internal M.2 SATA drives, when they are present in the M.2 mini-storage module option.

  • Each controller is listed separately in Cisco UCS Manager. You can enable or disable the sSATA controller in Cisco UCS Manager. See Enabling SATA Mode.

Enabling SATA Mode

Perform this procedure in Cisco UCS Manager.

Procedure
Step 1

Set the SATA mode.

  1. To change the M.2 state for the sSATA controller, change it in the storage sub-profile of the service profile that is assigned to the blade server. Choices are:

    • LSI SW RAID SWR—Enable the embedded sSATA RAID controller for control of internal SATA M.2 drives.

    • AHCI—Enable control of the internal SATA M.2 drives by AHCI through your OS rather than the embedded RAID controller.

    • Disabled—Disable the embedded sSATA RAID controller.
Step 2

Press F10 to save your changes and exit.

Installing LSI MegaSR Drivers For Windows and Linux


Note
The required drivers for this controller are already installed and ready to use. However, if you will use this controller with Windows or Linux, you must download and install additional drivers for those operating systems.

This section explains how to install the LSI MegaSR drivers for the following supported operating systems:

  • Microsoft Windows Server

Linux Drivers
Downloading the Driver Image File

See Downloading the MegaSR Drivers for instructions on downloading the drivers. The Linux driver is included in the form of dud-[driver version].img, which is the boot image for the embedded MegaRAID stack.


Note
The LSI MegaSR drivers that Cisco provides for Red Hat Linux and SUSE Linux are for the original GA versions of those distributions. The drivers do not support updates to those OS kernels.
Preparing Physical Thumb Drive for Linux

This topic describes how to prepare physical Linux thumb drive from the driver image files.

This procedure requires a CD or DVD drive that you can use to burn the ISO image to disk; and a USB thumb drive.

Alternatively, you can mount the dud.img file as a virtual floppy disk, as described in the installation procedures.

For RHEL and SLES, you can use a driver disk utility to create disk images from image files.

Procedure
Step 1

Download the Cisco UCS B-Series drivers ISO, as described in Downloading the MegaSR Drivers and save it to your Linux system.

Step 2

Extract the dud.img or dd.iso driver file:

Note 

For RHEL 7.1 and later, there is no dud.img file--the driver is contained in a dd.iso file.

  1. Burn the Cisco UCS C-Series Drivers ISO image to a disc.

  2. Browse the contents of the drivers folders to the location of the embedded MegaRAID drivers: /<OS>/Storage/Intel/C600-M5/

  3. Expand the Zip file, which contains the folder with the driver files.
Step 3

Copy the driver update disk image dud-[driver version].img (or dd.iso) to your Linux system.

Step 4

Insert a blank USB thumb drive into a port on your Linux system.
Step 5

Create a directory and mount the dud.img or dd.iso image to that directory:

Example:
mkdir <destination_folder>
mount -oloop <driver_image> <destination_folder>
Step 6

Copy the contents in the directory to your USB thumb drive.
Installing the Red Hat Enterprise Linux Driver

For the specific supported OS versions, see the Hardware and Software Compatibility Matrix for your server release.

This topic describes the fresh installation of the RHEL device driver on systems that have the embedded MegaRAID stack.


Note

If you use an embedded RAID controller with Linux, both the pSATA and the sSATA controller must be set to LSI SW RAID mode.

Before you begin

Before you install this driver on the sSATA embedded controller, you must configure a RAID drive group.

To access the configuration utility, open the BIOS Setup Utility, go to the Advanced tab, and then choose the utility instance for the sSATA embedded controller: LSI Software RAID Configuration Utility (sSATA).

Procedure
Step 1

Prepare the dud.img (or dd.iso) file using one of the following methods:

Note 

For RHEL 7.1 and later, there is no dud.img file--the driver is contained in a dd.iso file.
Step 2

Extract the dud.img (or dd.iso) file:

  1. Burn the Cisco UCS C-Series Drivers ISO image to a disk.

  2. Browse the contents of the drivers folders to the location of the embedded MegaRAID drivers: /<OS>/Storage/Intel/C600-M5/

  3. Copy the dud-<driver version>.img (or dd.iso) file to a temporary location on your workstation.

  4. If you are using RHEL 7.x, rename the saved dd.iso to dd.img.

    Note 

    If you are using RHEL 7.x, renaming the dd.iso file to dd.img simplifies this procedure and saves time. The Cisco UCS virtual drive mapper can map only one .iso at a time, and only as a virtual CD/DVD. Renaming the file to dd.img allows you to mount the RHEL installation ISO as a virtual CD/DVD and the renamed dd.img as a virtual floppy disk or removable disk at the same time. This avoids the steps of unmounting and remounting the RHEL ISO when the dd.iso driver file is prompted for.

Step 3

Start the Linux driver installation using one of the following methods:

  • To install from local media, connect an external USB CD/DVD drive to the server and then insert the first RHEL installation disk into the drive. Then continue with Step 5.

  • To install from virtual disk, log in to the server’s Cisco IMC interface. Then continue with the next step.
Step 4

Launch a Virtual KVM console window and click the Virtual Media tab.

  1. Click Add Image and browse to select your remote RHEL installation ISO image.

    Note 

    An .iso file can be mapped only as a virtual CD/DVD.

  2. Click Add Image again and browse to select your RHEL 6.x dud.img or the RHEL 7.x dd.img file that you renamed in step 2.

    Note 

    Map the .img file as a virtual floppy disk or virtual removable disk.

  3. Check the check boxes in the Mapped column for the media that you just added, then wait for mapping to complete.

Step 5

Power-cycle the target server.
Step 6

Press F6 when you see the F6 prompt during bootup. The Boot Menu window opens.

Note 

Do not press Enter in the next step to start the installation. Instead, press e to edit installation parameters.

Step 7

On the Boot Menu window, use the arrow keys to select Install Red Hat Enterprise Linux and then press e to edit installation parameters.

Step 8

Append one of the following blacklist commands to the end of the line that begins with linuxefi:

  • For RHEL 6.x (32- and 64-bit), type:

    linux dd blacklist=isci blacklist=ahci nodmraid noprobe=<atadrive number>

    Note 

    The noprobe values depend on the number of drives. For example, to install RHEL 6.x on a RAID 5 configuration with three drives, type:

    Linux dd blacklist=isci blacklist=ahci nodmraid noprobe=ata1 noprobe=ata2

  • For RHEL 7.x (32- and 64-bit), type:

    linux dd modprobe.blacklist=ahci nodmraid
Step 9

Optional: To see full, verbose installation status steps during installation, delete the Quiet parameter from the line.

Step 10

On the Boot Menu window, press Ctrl+x to start the interactive installation.

Step 11

Below Driver disk device selection, select the option to install your driver .img file. (Type r to refresh the list if it is not populated.)

Note 

The installer recognizes the driver file as an .iso file, even though you renamed it to dd.img for mapping.

Type the number of the driver device ISO in the list. Do not select the RHEL ISO image. In the following example, type 6 to select device sdb: 

5) sr0 iso9660 RHEL-7.6\x20Server.x
6) sdb iso9660 CDROM
# to select, ‘r’ - refresh, or ‘c’ -continue: 6

The installer reads the driver file and lists the drivers.
Step 12

Under Select drivers to install, type the number of the line that lists the megasr driver. In the following example, type 1: 

1) [ ] /media/DD-1/rpms/x86_61/kmod-megasr-18.01.2010.1107_e17.6-1.x86_61.rpm
# to toggle selection, or ‘c’ -continue: 1

Your selection is displayed with an X in brackets.

1) [X] /media/DD-1/rpms/x86_61/kmod-megasr-18.01.2010.1107_e17.6-1.x86_61.rpm
Step 13

Type c to continue.

Step 14

Follow the RHEL installation wizard to complete the installation.
Step 15

When the wizard’s Installation Destination screen is displayed, ensure that LSI MegaSR is listed as the selection. If it is not listed, the driver did not load successfully. In that case, select Rescan Disc.

Step 16

After the installation completes, reboot the target server.
Installing the SUSE Linux Enterprise Server Driver

For the specific supported OS versions, see the Hardware and Software Compatibility Matrix for your server release.

Replacing a Boot-Optimized M.2 RAID Controller Module

The Cisco Boot-Optimized M.2 RAID Controller module connects to the mini-storage module socket on the motherboard. It includes slots for two SATA M.2 drives, plus an integrated 6-Gbps SATA RAID controller that can control the SATA M.2 drives in a RAID 1 array.

Cisco Boot-Optimized M.2 RAID Controller Considerations

Review the following considerations:


Note

The Cisco Boot-Optimized M.2 RAID Controller is not supported when the server is used as a compute-only node in Cisco HyperFlex configurations.

  • The minimum version of Cisco IMC and Cisco UCS Manager that support this controller is 4.0(4) and later.

  • This controller supports RAID 1 (single volume) and JBOD mode.


    Note

    Do not use the server's embedded SW MegaRAID controller to configure RAID settings when using this controller module. Instead, you can use the following interfaces:

    • Cisco IMC 4.0(4a) and later

    • BIOS HII utility, BIOS 4.0(4a) and later

    • Cisco UCS Manager 4.0(4a) and later (UCS Manager-integrated servers)

  • A SATA M.2 drive in slot 1 (the top) is the first SATA device; a SATA M.2 drive in slot 2 (the underside) is the second SATA device.

    • The name of the controller in the software is MSTOR-RAID.

    • A drive in Slot 1 is mapped as drive 253; a drive in slot 2 is mapped as drive 254.

  • When using RAID, we recommend that both SATA M.2 drives are the same capacity. If different capacities are used, the smaller capacity of the two drives is used to create a volume and the rest of the drive space is unusable.

    JBOD mode supports mixed capacity SATA M.2 drives.

  • Hot-plug replacement is not supported. The server must be powered off.

  • Monitoring of the controller and installed SATA M.2 drives can be done using Cisco IMC and Cisco UCS Manager. They can also be monitored using other utilities such as UEFI HII, PMCLI, XMLAPI, and Redfish.

  • To upgrade and manage firmware for the controller and M.2 drives by using Cisco UCS Manager, refer to the Cisco UCS Manager Firmware Management Guide.

  • The SATA M.2 drives can boot in UEFI mode only. Legacy boot mode is not supported.

  • If you replace a single SATA M.2 drive that was part of a RAID volume, rebuild of the volume is auto-initiated after the user accepts the prompt to import the configuration. If you replace both drives of a volume, you must create a RAID volume and manually reinstall any OS.

  • We recommend that you erase drive contents before creating volumes on used drives from another server. The configuration utility in the server BIOS includes a SATA secure-erase function.

  • The server BIOS includes a configuration utility specific to this controller that you can use to create and delete RAID volumes, view controller properties, and erase the physical drive contents. Access the utility by pressing F2 when prompted during server boot. Then navigate to Advanced > Cisco Boot Optimized M.2 RAID Controller.

Replacing a Cisco Boot-Optimized M.2 RAID Controller

This topic describes how to remove and replace a Cisco Boot-Optimized M.2 RAID Controller. The controller board has one M.2 socket on its top (Slot 1) and one M.2 socket on its underside (Slot 2).

Procedure

Step 1

Remove the controller from the server:

  1. Decommission, power off, and remove the blade server from the chassis.

  2. Remove the top cover from the server as described in Removing a Blade Server Cover.

  3. Press out on the securing clips to disengage the controller from the socket.

  4. Pull straight up on the controller to remove it.

Step 2

If you are transferring SATA M.2 drives from the old controller to the replacement controller, do that before installing the replacement controller:

Note 

Any previously configured volume and data on the drives are preserved when the M.2 drives are transferred to the new controller. The system will boot the existing OS that is installed on the drives.

  1. Use a #1 Phillips-head screwdriver to remove the single screw that secures the M.2 drive to the carrier.

  2. Lift the M.2 drive from its socket on the carrier.

  3. Position the replacement M.2 drive over the socket on the controller board.

  4. Angle the M.2 drive downward and insert the connector-end into the socket on the carrier. The M.2 drive's label must face up.

  5. Press the M.2 drive flat against the carrier.

  6. Install the single screw that secures the end of the M.2 SSD to the carrier.

  7. Turn the controller over and install the second M.2 drive.

Figure 34. Cisco Boot-Optimized M.2 RAID Controller, Showing M.2 Drive Installation
Step 3

Install the controller to its socket on the motherboard:

  1. Position the controller over the socket, with the controller's connector facing down and at the same end as the motherboard socket. Two alignment pegs must match with two holes on the controller.

  2. Gently push down the socket end of the controller so that the two pegs go through the two holes on the carrier.

  3. Push down on the controller so that the securing clips click over it at both ends.
Step 4

Replace the top cover to the server.
Step 5

Return the blade server to the chassis and allow it to be automatically reacknowledged, reassociated, and recommissioned.

Recycling the PCB Assembly (PCBA)

Each blade server has a PCBA that is connected to the blade server's faceplate and sheet metal tray. You must disconnect the PCBA from the blade server's faceplate and tray to recycle the PCBA. Each blade server is attached to the faceplate and tray by the following screws:

  • Faceplate: Two M2x0.4mm screws.

  • Tray: 16 M3x0.5mm screws.

You will need to recyle the PCBA for each blade server.

Before you begin


Note

For Recyclers Only! This procedure is not a standard field-service option. This procedure is for recyclers who will be reclaiming the electronics for proper disposal to comply with local eco design and e-waste regulations.

To remove the printed circuit board assembly (PCBA), the following requirements must be met:

  • The server must be disconnected from facility power.

  • The server must be removed from the equipment rack.

  • The server's top cover must be removed. See Removing a Blade Server Cover.

Procedure

Step 1

Using a screwdriver, rotate each of the faceplate screws counter clockwise until it disengages.

The following figure shows the location of these screws.

Figure 35. Location of PCBA Mounting Screws on Faceplate
Step 2

Using a screwdriver, rotate each of the mounting screws counter-clockwise until it disengages.

The following figure shows the location of these screws.

Figure 36. Location of PCBA Mounting Screws on Blade Server Tray
Step 3

Detach the PCBA from the faceplate and tray, and dispose of all parts properly.
