Hardware and Software Interoperability
For detailed information about storage switch, operating system, adapter, adapter utility, and storage array interoperability, see the Hardware and Software Interoperability Matrix for your release located at:
http://www.cisco.com/en/US/products/ps10477/prod_technical_reference_list.html
Transceivers Specifications
The Cisco UCS C-Series servers supports a wide variety of 10 Gigabit Ethernet connectivity options using Cisco 10GBASE SFP+ modules.
Table 2 and Table 3 details the controllers and the supported transceivers.
Firmware Files
The C-Series software release 2.0(1) includes the following software files:
Note Always upgrade both the BIOS and the Cisco IMC from the HUU ISO. Do not upgrade individual components (only BIOS or only Cisco IMC), since this could lead to unexpected behavior. If you choose to upgrade BIOS and the Cisco IMC individually and not from the HUU ISO, make sure to upgrade both Cisco IMC and BIOS to the same container release. If the BIOS and the Cisco IMC versions are from different container releases, it could result in unexpected behavior. Cisco recommends that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together.
Host Upgrade Utility
The Cisco Host Upgrade Utility (HUU) is a tool that upgrades the following firmware:
– Intel Ethernet i350 PCI Server Adapter
– 5709 Dual and Quad port adapters
– 57712 Dual port adapter SFP+
– 57712 Dual port adapter 10GBaseT
The image file for the firmware is embedded in the ISO. The utility displays a menu that allows you to choose which firmware components to upgrade. For more information on this utility see:
http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html
Starting with 1.4 release, separate ISO images of Host Upgrade Utility are available for different server platforms.
The ISO image is now named as ucs-<server_platform>-huu-<version_number>.iso.
The Cisco Host Upgrade Utility contains the following files:
HDD Firmware
Following table lists the supported HDD models and the firmware versions that can be updated using Host Upgrade Utility (HUU).
System Requirements
The management client must meet or exceed the following minimum system requirements:
Updating the Firmware
Use the Host Upgrade Utility to upgrade the C-Series firmware. Host Upgrade Utility can upgrade the following software components:
- BIOS
- Cisco IMC
- Cisco VIC Adapters
- LSI Adapters
- LAN on Motherboard Settings
- PCIe adapter Firmware
- HDD firmware
All firmware should be upgraded together to ensure proper operation of your server.
Note Cisco recommends that you use the Update All option from the Host Upgrade Utility to update the firmware versions of Cisco IMC, BIOS and all other server components (VIC, RAID Controllers, PCI devices, and LOM) together.
Best Practice to Upgrade the Firmware
If you are upgrading from versions 1.5(3) or before, using any one of the available interfaces, we recommend you reboot Cisco IMC before starting the upgrade. Cisco IMC reboot before the upgrade eliminates issues you may face while upgrading.
Upgrading BIOS and Cisco IMC Firmware
Cisco provides the Cisco Host Upgrade Utility to assist you in upgrading the BIOS, Cisco IMC, LOM, LSI storage controller, and Cisco UCS Virtual Interface Cards firmware to compatible levels.
Note When upgrading the Cisco IMC firmware for the UCS C-series M3 platforms, ensure that you update using the full image (for example upd-pkg-c2XX-m3-Cisco IMC.full.*.bin).
The correct and compatible firmware levels for your server model are embedded in the utility ISO.
To use this utility, use the Cisco Host Upgrade Utility User Guide which includes the instructions for downloading and using the utility ISO. Select the guide from this URL:
http://www.cisco.com/en/US/products/ps10493/products_user_guide_list.html

Workaround Power off and Power on the system.(CSCui52162)
Symptom A UCS C420 M3 will occasionally power down when a reload is issued.This has been experienced on a C420 integrated with UCSM running 2.1(1e). The Cisco IMC version is 1.4(8e). The problem can occur with a reboot from Windows Server 2008 R2 Update 1. But also the problem can occur when CTRL-ATL-DEL is issued from KVM during bootup (this normally only causes a reboot).
Workaround No workaround is available at this time.(CSCuh52222)
Symptom The boot device "Cisco Virtual CD/DVD 1.22" for the network mounted Virtual media device does not appear in the BIOS boot order.
Workaround The C260 BIOS supports only up to 8 USB mass storage devices during the BIOS POST. When more than 8 USB physical and/or virtual devices are present, the BIOS will omit some devices from the boot order list. As a workaround, to boot off the missing virtual media device in the boot order list, disable Virtual drives (HUU, SCU, Drivers, and HV) in the FlexFlash storage temporarily through Cisco IMC WebUI before mounting virtual media device and enable it back after unmounting the virtual media device. The options to disable/enable FlexFlash virtual drives in the Cisco IMC WebUI can be found in the Storage->Cisco FlexFlash->Configure Operational Profile. (CSCue82433)
Symptom Number of Enabled CPU core changes done in the Processor configuration under BIOS setup is not reflected in the OS.This affects only Intel Xeon(C) 26XX Series or Intel Xeon(C) 24XX series CPUs (M series).
Workaround No workaround. However, CPU core count retained after upgrade.(CSCuj03896)
Broadcom Controller
Symptom ESXi hosts may loose network connectivity intermittently when connected to bnx2 driver based NICs such as BCM 5709.

Cisco IMC
Symptom Occasionally, spurious faults are generated when a physical drive is removed.
Workaround Ignore the spurious faults. (CSCue82218)
Symptom No physical drive specific faults are generated during virtual drive changes.
Workaround Monitor virtual drive faults instead of physical drive faults. Alternately, check the physical drive status through the Cisco IMC web interface. (CSCud11929)
Cisco Flexible Flash Controller
Symptom FlexFlash Degraded RAID message with only 1 SD card.
Workaround To resolve this issue, follow these steps:
Step 1 Remove all the SD cards from the system and reboot Cisco IMC once, this error is erased.
Step 2 If Cisco IMC reboot is not possible, then you need to put 2 SD cards in the system (if it had 1), launch SCU and do a Hypervisor SYNC, this error will go. (CSCuh20203)
LSI
Symptom When SuperCap is fully charged, its status should display “Charged” or “None.” In its current state it constantly displays “Charging” even when capacitance is 100%. The getbbuproperties command for MegaCLI/StorCLI should yield BBU/SuperCap details. Currently, a message displays that hardware is not supported.
Workaround SuperCap “Charging” when 100% is display issue only. No impact on performance or VDs. Will be updated in the next NMR release.The getbbuproperties command output issue will be addressed in production NMR release.(CSCui17382)
Symptom Replacing LSI MEGARAID 9260-8I BBU gets stuck with moderate fault and battery requires reconditioning: please initiate a LEARN cycle. Current Cache Policy: WriteThrough seen and Moderate Fault seen on Cisco IMC GUI.
Workaround Manual re-learn must be started from MegaCLI instead of Cisco IMC GUI. (CSCui48317)
Symptom Locate LED for the Nytro SSD Drives does not work from LSI WebBIOS Utility.
This is an expected behavior as Nytro SSDs will be placed inside the Heat Sink and not visible to users.So on locating Nytro SSDs, LED will not glow. The locate LED is not usable with Nytro SSD Drives. (CSCuh74619)
OS
Symptom UEFI installation of RHEL6.3 and RHEL 6.4 fails under certain circumstances. OS install hangs at loading vmlinuz.

Workaround Please include inHierarchical="false" in the xml request. (CSCuj74341)
Cisco IMC
Symptom C-series M3 intermittently losing access to flexflash and SD card.
Workaround Reset the flexflash controller from WEBUI/CLI or reboot Cisco IMC. (CSCuh33982)
XML API
Symptom XMLAPI server goes dead several days after frequent processing of 11+ simultaneous xmlapi queries.
Workaround Complete the following steps:
Step 1 Use aaaLogin to obtain the XML API Session cookie and use the cookie to query the below classes
Step 2 Query the below objects at 1 minute interval using the XML API session cookie:
- equipmentFan
- storageLocalDiskSlotEp
- storageController (this inHierarchial=true is already retrieving storageLocalDisk, storageVirtualDrive, and storageRaidBattery)
- equipmentPsu
Step 3 Query the below objects at 5 minutes interval using the XML API session cookie.
Do not logout of the cookie obtained in step 1. Also, the cookie will not expire as client is query xmlapi well before the cookie expires in 10 minutes) (CSCui20368)
BIOS
Symptom Server hangs with blinking cursor before loading the OS, in the follow on (turnup) boot after association is complete.
Workaround Restart the server from UCSM. (CSCua86734)
Symptom The following error is reported in the Cisco IMC SEL Logs:
Workaround None. Ignore this error as it does not have any functional impact on the system. (CSCub21476)
Symptom After upgrading the LOM firmware from this release, LOM PXE boot entries gets shuffled in the boot order. You may experience that system cycle through all other network boot devices before trying to boot from LOM PXE boot.
Workaround Go to BIOS setup boot manager page and reorder the network boot device entries as per the need. (CSCui41691)
Cisco IMC
Symptom Storage controller information is not populated in Cisco IMC. As a result, the storage controller becomes unmanageable by Cisco IMC.
Workaround Complete the following procedure:
Step 3 From the Cisco IMC, power on the host.
Step 4 Wait for the storage subsystem to have time to refresh its data (sometimes requires 5 or more minutes), and log out and log in again to the Cisco IMC WebUI. You will know this is successful when the proper controller list shows up in the Storage tab. (CSCuh60054)
VIC Firmware
Symptom Sometimes, when a server is connected to N3548, the link goes down after the server is rebooted.
Workaround Reboot server once more, and flap the link on N3548 at the same time. (CSCui17668)
Cisco IMC
Symptom Two mappings with same volumeName may be created, causing undesired effect.
Workaround Do "show mapping [detail]" and delete the failed mapping before attempting another mapping with same volumeName. (CSCud52530)
Symptom Sometimes LUN details are not updated in SNMP inventory.
Workaround Restart the Cisco IMC to force refresh of the SNMP LUN information. (CSCtz86019)
Symptom Sometimes upon the initial login to the WebUI after restoring the Cisco IMC to factory defaults, an error popup saying "Error: unexpected error" displays.
Workaround Log out of the WebUI and log back in. (CSCud69474)
Symptom When learn cycle is started on TMM-C SuperCap from the WebUI or the CLI, it fails with the following error message:
This error message displayed is not very meaningful to understand why starting learn cycle failed for the TMM-C SuperCap.
Workaround The TMM-C SuperCap does not support starting learn cycle manually as they are always in transparent learn mode. This explains the failure in starting the learn cycle. A meaningful error message will be provided in future releases. (CSCud96082)
Symptom Some LSI MegaRAID controllers support only a subset of the RAID levels (0, 1, and 10), but pmcli create-virtual-drive command additionally displays 5, 6, 50, and 60 as candidates for virtual drive creation. But if one of the latter RAID levels is selected, the virtual drive creation fails.
Workaround The operation fails on these controllers, so instead specify a supported RAID level, or use WebUI to create virtual drives, as the WebUI only presents valid options to the user. (CSCud96669)
Symptom Occasionally a spurious fault is generated that a nonexistent drive is missing.
Workaround Ignore the spurious fault. (CSCue82487)
Symptom No fault and no SNMP traps are reported when a virtual drive consistency check fails.
Workaround Check the consistency check status using the Cisco IMC's web interface or host-based MSM or MegaCLI interface. (CSCud03744)
Symptom vmedia is not usable in BIOS boot order when using a VIC P81E card.
Workaround No workaround. This is a known behavior with P81e card. This card gets reset during host reboot, due to that vKVM and vMedia sessions are getting closed and BIOS boot order is lost due to power savings mode. The new generation VIC 1225 card does not have this issue if Cisco IMC network mode is configured to cisco_card. (CSCud08544)
Symptom SEL entries not appearing in fault page.
Workaround Clear the SEL. (CSCue83837)
Symptom Cisco Card and Shared LOM Extended mode cannot be set for the VIC 1225T adapter.
Workaround There is no workaround for this issue. (CSCue46850)
Symptom C420 Cisco IMC log can often contain many messages similar to this.
Workaround Disable Debug logging in Cisco IMC log. (CSCuc72105)
BIOS
Symptom Cannot setup the Cisco IMC. The system tries to boot, but cannot access Cisco IMC, and the following error message is displayed during Cisco IMC setup:
LSI
Symptom The SSD Caching is enabled even when SSD are not part of the virtual drive.
Workaround There is no effect on virtual drive performance when virtual drives do not have SSDs.(CSCuc13837)
Symptom LSI Storage controller Firmware upgrade using LSI GUI Application MSM for 9240-8i cards fail with “Controller Out of Memory Error”.
Workaround Use LSI CLI Application MegaCli for firmware upgrades on LSI 9240-8i cards. The MegaCli application displays the message that "Controller out of memory" but the firmware upgrade succeeded message is also seen along with system reboot needed for change to take effect. Ignore the message about "Controller out of memory" and reboot the system for LSI Firmware update to take effect. (CSCtz86993)
Symptom ESXi 5.0 experiences PSOD with following backtrace:

Symptom When mapping a removal media using Mac Client, the USB device only supports Read-Only mode.
Workaround Use Windows client or Linux 32 bit client. (CSCty32452)
Symptom When running the KVM Viewer client on a 64 bit Linux OS, block devices such as a USB stick or floppy drive will have the read only box checked when you open the vMedia tab. Trying to uncheck the read only box will fail, and devices can only be mapped as read only.
Workaround Use a 32 bit Linux OS or Windows OS for the client system running the KVM Viewer application. (CSCty37812)
Symptom When using the KVM Viewer client application with a 64 bit Linux OS, mapping both floppy disk and removable disk at the same time will cause improper functioning of the application that is, the drive data is invalid and/or cannot be read. Even mapping only a single drive (floppy or removable disk) at a time can yield unexpected failures. For example, after mapping and unmapping a USB stick, click on the exit button of the vMedia tab and reopen the vMedia tab. Now, if you try map the device again the vMedia tab will crash and all the mapped devices will be unmapped.
Note Mapping of CD-ROM drives and image files works properly, this problem is observed only when mapping physical Linux block devices such as /dev/sdX.
Workaround Perform the following steps to map physical block devices:
Step 1 Map only a single physical block device at a time (not both floppy and removable device at a time). This will usually work, but may have occasional unexpected failures. Restart the client if the vMedia tab stops functioning.
Step 2 Generate an img file of the block device contents and map this instead, this has no known issues.
Step 3 Use a 32 bit Linux OS / Windows OS / Mac OS client system to run the KVM Viewer/vMedia application. (CSCty42187)
Symptom Cisco IMC recognizes only the SuperCap and all other information like the charge and charging state is not available.
Symptom RAID subsystem Virtual Drive write performance can drop without warning from the Cisco IMC.

Symptom SD card partition sizes appear as trash values for SCU,HUU and drivers during downgrade.
Workaround Upgrade to release 1.5(4x) and create a single partition, and then downgrade to a prior release. The partition sizes then appear to be 2097151 MB. (CSCuj84718)
Symptom Changing multiple configuration with Port parm fails from Cisco IMC config only.
Workaround Complete the following steps:
Step 1 Set the mode to Dedicated and the redundancy to None.
Step 2 Save the changes to the system.
Step 3 Set the auto-negotiation field to Yes. (CSCuj67995)
Symptom If an SD card which has 4 partitions (SCU, HV, Drivers and HUU) is configured as 1 partition (HV) with Cisco IMC 1.5(4), then the data stored in HV is lost.
In the transition from 4 partition configuration to a single partition, only configuration details are modified. Data on the SD remains intact. So after migrating to a single partition (HV), the HV partition will retain SCU data only if SCU has a valid file system during configuration migration.
Workaround After migrating to a single partition (HV) configuration, format and install the required OS on the HV partition. (CSCuj52943)
Symptom Modifying the Bios Token Value and committing the change to the system using the CLI does not prompt for rebooting the server in the following process:

Workaround Upgrade to 1.5(x) build. (CSCuj41445)
Symptom Occasionally after a Cisco IMC upgrade, one may see an error dialog box "Error: Unexpected error" in Web UI on main page upon the very first login. The Storage data may also be blank or invalid. Sometimes occurs during the very first login after a Cisco IMC upgrade. It may be related to upgrade from 1.4x to 1.5.
Workaround Logging out and back in will fix it, but probably just because it takes time; therefore, just waiting a few minutes and refreshing the WebUI may fix the problem, also.(CSCud17092)
Cisco usNIC
Symptom Cisco IMC limits the configurable VNICs, and usNICs to 229.
Workaround None. The remaining vnics are reserved for the internal adapter usage. Of these remaining VNICs, 4 are mandatory- 2 enics, and 2 fnics. When you configure 16 VNICs (including the 2 mandatory ENICs), you are left with 229-2(FNICs)-16(ENICs)= 211 usNICs. (CSCul56178)
LSI
Symptom The battery is in a degraded state because it requires a manual (user initiated) relearn cycle.This is required of batteries that have been in use for over 1 year to accurately measure the battery's remaining capacity.
Workaround A manual (deep cycle) relearn must be started by the user. This can be done via the MegaCLI utility or from the Storage tab of the server Cisco IMC. A relearn can take several hours and up to a day to complete. It the battery still has sufficient capacity after the relearn is complete, it will go to optimal state and the VDs will switch back to WriteBack mode if that is how they configured prior to the relearn. (CSCuj83316)
Web Management
Symptom The WebUI DIMM "Operability" field in the memory inventory does not indicate failed DIMMs correctly.
Workaround The issue is observed only in the memory inventory reported by the WebUI. The BIOS reports the DIMM status properly in the BIOS Setup. So, if WebUI shows any DIMM as Inoperable, please check the status of all DIMMs on all the memory risers at Advanced -> Memory Configuration page of the BIOS Setup to get the correct status on the DIMMs. (CSCtx16030)
Firmware Upgrade
Symptom Downgrading from release version 1.5(3) to 1.5(1) release version does not throw an error in Host Upgrade Utility.
Workaround This is not an issue. Though an error is not reported, the update will not proceed. (CSCui82263)
Cisco IMC
Symptom C240-M3 does not power up after firmware upgrade to 1.5(1B). While upgrading via HUU from firmware 1.4(6c) to 1.5(1b), HUU did not upgrade Cisco IMC to 1.5(1b) even though it reported as successfully completed.
Workaround Manually force Cisco IMC and BIOS update to fix it. (CSCuf52723)
Symptom Base Distinguished Name (base-dn) parameter syntax is different in new LDAP implementation.
Workaround Use the following syntax:
Symptom With Windows Active Directory, the child domain user login will fail with partial login name.
Workaround Provide fully qualified login name to make it work. (CSCuh71550)
Symptom Intel VTD and ATS are required BIOS setting for usNIC. However, there is no warning message in Cisco IMC if these parameters are not enabled when usNIC is configured.
Workaround Make sure Intel VTD and ATS are enabled in BIOS setting when usNIC is configured (CSCuh39061)
Symptom When upgrading the C24 M3 from 1.4.7a to 1.4.7f using the HUU (option to upgrade all), the servers fans run at almost double the speed they were running at on 1.4.7a.

Workaround AC power cycle the chassis to recover. (CSCug65160)
Symptom The PSU firmware revision may only be partially available when the PSU does not have AC power.
Workaround Connect the AC power to the PSU. The full firmware revision will be available. (CSCtx43305)
LSI
Symptom When booting a Cisco C22x or C24x server, RAID levels are displayed when loading the LSI Option ROM. However, not all supported RAID levels are displayed.
Workaround This is done to distinguish between different 9240 controllers. Some of them support RAID5, and some do not. There are 2 products under the same 9240 name. However, there is not enough space in the name field to list every possible RAID level supported. This is why a partial list of RAID levels is displayed. (CSCue10144)
Symptom BBU charging status always shows as Charging and percentage of charging never reaches to 100%. It always shows 67%.
Workaround This is the new change in the firmware. The Battery re-learn cycle is completed successfully and battery is charged back to 67% which is in the band gap where charging will be stopped by LSI firmware and battery will be declared optimal. This is the charge needed to retain data upto 48 hours. The Charging Status showing "Charging" as there will be some leakages and battery will slowly loose charge and hence the battery will be charging. (CSCug95648)
Symptom BBU status is showing as discharging and the charge % is stuck at 64%. Battery replacement alerts on the server. Server is showing battery discharging and there is a moderate alert which says Status: Learning Cycle Needed?
Symptom Hang occurs when using 64-bit MSM 12.08.03.03.
Workaround Use 32 bit version of MSM. (CSCud13257)
Symptom Virtual Drive long running operations such as Initialization. Rebuild, Consistency Check progress are not reported correctly on Cisco IMC WebUI and PMCLI if multiple Virtual drives are undergoing the long running operations simultaneously. The progress will be reported correctly on the first virtual drive but on the subsequent virtual drives you see "Foreground Initialization is in progress" but 0 for Progress and Elapsed time values.
Workaround Start long running operations one at a time for the virtual drives to get the correct updates on the operation in progress. Or wait for the operation to complete on one virtual drive before querying the status or progress on the other virtual drives in the list. (CSCue18569)
Host Upgrade Utility
Symptom Firmware Update on Emulex LPe16002 will fail when tried from HUU on certain servers.
Workaround Emulex LPe16002 is already at the same firmware level of what HUU is carrying. So effectively an update is not needed. alternatively move the card to another server and try update. (CSCui09482)
SNMP
Symptom C200 or Nexus 1010 Hardware generates snmp traps with the following OID's
- 1.3.6.1.4.1.3183.1.1.6.880384

- 1.3.6.1.4.1.3183.1.1.6.880513
- 1.3.6.1.4.1.3183.1.1.6.0
There are no MIB's available on Cisco's website to define these OID's
Workaround Use Intel PET_EVENTS.mib and manually define traps. (CSCtu14606)
Symptom When doing a MIB walk on several MIBs, they give a "No more variables left in this MIB View (It is past the end of the MIB tree)" error at the end. Failing MIBs: snmpVacmMIB
Notice MIB ends cleanly, and there is no error
To have, "No more variables left in this MIB View" when there are more mibs left to walk.
The final oid seen is 1.3.6.1.6.3.16.1.5.2.1.6, and within the error-status of the get-response packet, we get noSuchName(2), and this should be noError(0).
Web Management
Symptom Sometime with Windows 2008 and IE 8.0 Cisco IMC WEB UI login prompt will not be seen
Workaround Add Cisco IMC IP to IE 8.0 trusted sites list. In the Internet Explorer browser window, select Tools -> Internet options -> Security -> Trusted Sites -> Sites -> Add (CSCuc19323).
Symptom After clicking on "Add Exception", user is prompted with a window which says "certificate is valid" and the "Confirm Security Exception" button is greyed out.
Workaround Clear the cache or refresh multiple times the issue will be resolved. (CSCuh76949)
Cisco IMC
Symptom FlexFlash operational profile is not preserved on downgrade from 1.5(1x), resulting in all FlexFlash partitions being visible to the operating system.
Workaround Set the operational profile again after downgrade. (CSCuf53059)
Intel RSTe
Symptom Creating RAID volumes from Intel RSTe software RAID option ROM (Control-I) is not supported.
Workaround Use LSI software RAID, LSI hardware RAID, or OS SW RAID. (CSCuf02487)
Symptom Hard drive Critical events are seen in SEL during server bootup when using Intel RSTe.
Workaround This is not a real hard drive fault. The HDD Critical events reported becomes normal after system boots up and can be ignored. If real HDD fault, then Critical event generated on HDD will be persistent and does not indicate normal even after server has booted up and in this case, user need to take action to replace that HDD. (CSCue72256)
BIOS
Symptom LSI Web BIOS may not launch on pressing Ctrl+H.
Workaround During BIOS post, press F6 to bringup the boot override list and select the appropriate entry to launch the web bios. (CSCuc75369)

Symptom Occasionally, when BIOS starts, the following message is displayed:
Workaround This message can be ignored.(CSCtx27907)
Symptom When Broadcom 5709 Gigabit Ethernet adapter is plugged into one of the PCIE slots, the server gets stuck at the BIOS post screen during the booting process.
Workaround Upgrade the firmware on the Broadcom 5709 Gigabit Ethernet adapter to version 5.2.7 or later. (CSCtx92042)
Symptom BIOS downgrade using the iFlash32 utility, from 1.4.x to the older version 1.2.x fails.
Workaround Use the startup.nsh script available in the 1.2.x container for the downgrade. This script will execute the BIOS downgrade successfully. (CSCtr93601)
Cisco IMC
Symptom Cisco IMC CLI does not report PID of HDD when using Intel RSTe.
Symptom For a server with Virident card (or any card for which fan control has specific modifications), if Cisco IMC is reset to factory defaults when host is on, then the fan control will go back non-card specific settings. This might imply lower fan speeds and can cause heating up of cards if there are cards present that require higher fan speeds (ex: Virident FlashMaxII card). This is because information about cards is available to Cisco IMC from host, and when a factory default is done, this information is erased.
Workaround Reboot the host, so that Cisco IMC can get card specific information and bump up fan speeds as required. (CSCue54670)
Symptom When you power on the chassis with some PS power cables disconnected, the system health LED on the front panel stays green, though some power supplies have no input voltage.
Workaround Connect all cables from APC power to the power supply securely. (CSCtg92856)
Symptom USB Key which is inserted on a Mac can be forced to be read-only.
Workaround Mac users must unmount the removable drive before mapping.
Step 1 Run the following command from the command line interface:
diskutil unmount /Volumes/<Volume name>
Step 2 In the KVM/vMedia client, clear the Read Only checkbox. At this point, the user may be prompted asking if they wish to stop automatic mounting of the drive. Click Yes.
Step 3 Proceed with mapping the drive.
These steps are time-sensitive, as the Mac OS is aggressive about re-mounting drives that have been unmounted. If the drive does get re-mounted by the OS before completing the steps, repeat the steps.
Alternatively, unmap the USB stick, use the Finder to eject the device, wait for the device to disappear from the vMedia Client view, and then physically remove and re-insert it while the vMedia session is running. As above, click Yes to the questions asking about preventing automatic mounting of the drive. (CSCtz52715)
Symptom On some Macs with spaces enabled, the vKVM popup notification that the session has ended can not be closed because trying to click the button causes the focus to move away from the space with the popup.
Workaround Move the vKVM main window to the same space with the popup notifier. Then, the popup can be dismissed by clicking on the button. (CSCua63839)
Symptom SNMPv1 traps are sent when SNMPv2 and SNMPv3 traps are enabled.
Symptom The KVM screen displays a blank screen.
Workaround Use the physical monitor to change the screen resolution. The following resolutions are supported:
- 640x480 (8bpp)
- 800x600 (8bpp)
- 1024x768 (8bpp)
- 1280x1024 (8bpp)
- 1600x1200 (8bpp)
- 1920x1080 (8bpp)

- 1280x1024 (16bpp)
- 1600x1200 (16bpp)
- 1920x1080 (16bpp)
- 1920x1200 (16bpp)
- 640x480 (24bpp)
- 800x600 (24bpp)
- 1024x768 (24bpp)
- 1280x1024 (24bpp)
- 640x480 (32bpp)
- 800x600 (32bpp)
- 1024x768 (32bpp)
- 1280x1024 (32bpp) (CSCtx00839)
Symptom After firmware updates, the Cisco IMC Web GUI and CLI might not display the Virtual Drive Information under the Virtual Drive tab and might display the Virtual Drive count as zero even though the Virtual Drive tab displays the list of virtual drives present in the system.
Workaround Restart the Cisco IMC. (CSCtx88183)
Symptom The SNMP Hard Disk Inventory starts numbering with 0 while the Cisco IMC HDD sensor starts with 1.
Workaround None. This symptom occurs because the SNMP Hard disk inventory matches with the storage inventory and both starts with index 0. The hard disk sensor numbering starts with 1 because it matches with the label in the SKU. You need to be aware of the difference and map it accordingly while browsing for a specific HDD detail across sensors and storage inventory. (CSCty58229)
Symptom The HDD presence cannot be viewed through SNMP.
Workaround Use either alternate interfaces or do SNMP query again for the HDD inventory after the action. (CSCty60975)
Symptom Duplicate SNMP traps are obtained when you insert Fan 2,4 and 5 in Cisco C22.
Symptom “Unable to communicate with FlexFlash” error message is seen after downgrading Cisco IMC to version 1.4.
Workaround User should select the Reset Flex Controller button twice if the SD card is of type SD253. If not, select the button only once. (CSCuc87936)
Intel Adapters
Symptom When multiple Intel network adapters are present and you enter the iSCSI configuration from one card, it allows you to change the configuration on all Intel cards. After the change, when one of the cards is removed, it appears that the option ROM of the remaining cards is overwritten by the card that was removed.
Workaround Enter the iSCSI configuration of the card that must be modified. Do not modify other cards when they are visible. This issue is only with iSCSI configuration and not with PXE configuration. (CSCuc52172)
LSI
Symptom If the number of Virtual Drives created in the LSI MegaRAID controller is greater than or equal to 50, the system will not boot from any of these Virtual Drives.
Workaround None. The system boots from MegaRAID Virtual Drives only if the number of Virtual Drives are lesser than or equal to 49. (CSCtg25373)
Symptom RHEL 6.2 Install to iSCSI target hangs when 2008 MEZZ card Option ROM is disabled on C220/240 servers.
Workaround 2008 LSI OPROM must always be enabled in System BIOS when it is present in the server. If users want to disable it, then during OS Installs, depending on the OS, they would need to blacklist the LSI MegaRAID driver for the 2008 MEZZ card so that system will not hang during install. (CSCua03604)
Symptom The following error message is displayed in some LSI RAID controllers when you navigate to Cisco IMC > Inventory > Storage > Battery Backup Unit.
Workaround None. This issue is currently under investigation. (CSCts37240)

Symptom Sometimes you cannot select a boot device from F6 screen.
Workaround No workaround. (CSCum79756)
Symptom Boot order varies when enabling or disabling the Option ROM.
Cisco IMC
Symptom On C460-M4 servers, memory RAS displays maximum performance when set to Mirroring.
Symptom On C460-M4 servers, boot-override has HUU, SCU as options in CLI
Symptom Cisco IMC upgrade from 1.4(5e) to 1.5(4) deletes HV partition.
Symptom Firmware version 1.5(4) does not recognize flex flash SD Card properly.
Workaround To recognize the SD Card correctly follow these steps:
Step 2 Downgrade the firmware to version 1.5(3d),
Step 3 Synchronize the card with SCU
Step 4 Upgrade the firmware to version 1.5(4).(CSCum60563)
Symptom With RHEL 6.5 installed on the server if Cisco IMC is rebooted, the IPMI (example: ipmitool) communication over KCS (system interface) between Host and Cisco IMC fails.
Workaround Reboot the RHEL 6.5 Operating System on the server. (CSCuo83800)
BIOS
Symptom Server enters BIOS setup menu when the boot devices that are configured in the service profile are not found. This impacts only C-series servers that are managed by Cisco UCS Manager.
Symptom UEFI PXE boot or UEFI iSCSI boot does not work when the boot mode is set to UEFI.
Workaround Use the legacy boot mode when using PXE or iSCSI boot. (CSCuj28644)
Symptom Unable to install Solaris 11U1 on C240 M3S with BIOS 1.5.4f.0
Workaround Make the following changes in the BIOS setup menu, before installing:
Step 1 Go to System BIOS (Press F2) -> PCI configuration—>MMCFG
Step 2 Change the value from Auto to 2 GB.
Step 3 Change the value of Memory Mapped IO above 4 G to Enabled.
Step 4 Save and reboot the system. Installation will complete. (CSCul23805)
Cisco IMC
Symptom Upgrading firmware with Host Upgrade Utility (HUU) can cause temporary storage faults while the upgrade is in progress. These faults are benign and will clear once the upgrade is complete.
HUU
Symptom While updating firmware from 1.5.3d to 1.5.4-2, the Update verify process will fail for QLE8362 after HUU update.
Workaround No workaround. This is just a string miss-match there is no functional impact. (CSCul99016)
LSI
Symptom Prepare for removal prepares a Hard drive for removal but LED on the HDD does not blink AMBER to indicate the drive is ready to be replaced. This happens only on direct connect C260-M3 configurations.
Symptom ESXi 5.5 Systems cannot be managed by LSI Applications such as MSM from remote clients. The issue is only for ESXi 5.5.
Symptom Importing Foreign configurations from LSI Applications like MSM / StorCli under Sles 11 SP3 results in system panic. This issue occurs only with the SLES 11 SP3 OS.
Workaround Users should attempt to Import Foreign configuration from LSI OPROM utility like WebBIOS (Cntrl+H) or user other Linux/Windows OS if possible to import the Foreign configuration. (CSCuj45957)
Symptom LSI MSM Application used to manage the LSI controller does not display the GUI version sometimes.
OS
Symptom New storage repository creation fails from XenCenter GUI, when Xen 6.2 is installed on a server with VIC 1225 and a LUN is mapped to the adapter. From the Xen Center GUI, if the LUN is chosen to create a new SR, it throws an error message.
Workaround Complete the following steps:
Step 1 Creating a new storage repository always works from command line. It fails only from the XenCenter GUI.
Step 2 Add an fnic entry to MODULE_INFO in devscan.py
Edit /opt/xensource/sm/devscan.py
Add 'fnic': 'Cisco HBA Driver',
Step 3 After adding this, creating a new storage repository from GUI will be successful. (CSCui71691)
Symptom VMware 5.5 fails to install on C240 M3 server. The following error message is displayed:
This issue is observed while installing VMware 5.5 on C240 M3 systems with Nvidia GPU cards.
Workaround Make the following changes in the BIOS before installing VMware 5.5:
Step 1 Go to System BIOS (Press F2) -> PCI configuration—>MMCFG.
Step 2 Change the value from Auto to 2GB.
Step 3 Change the value of Memory Mapped IO above 4 G to Enabled.
Step 4 Save and reboot the system, following which the installation will complete.(CSCul03884)
Symptom Cisco IMC Storage, Storage Log will list many "Unexpected sense: Encl PD 10 pathd7fe00bd, CDB: 1a 00 08 00 ff 00, Sense: 5/00/00". These same events will also show up in /var/log/messages file.
Workaround VMware seems to treat all storage devices the same way, regardless of whether they are SAS disks or just enclosures. The messages you are seeing means that the host (ESX) was sending mode sense commands to the enclosure and the enclosure does not give a valid response because mode sense commands are not a command that should be sent to an enclosure. So the unexpected sense messages from the enclosure are benign info messages.
There is way to "disconnect" the enclosure from the viewpoint of ESX. It should not have an adverse impact as the enclosure is not a usable storage device.
For now, you can try the following:
Step 2 Run this cmd: "esxcli storage core device list" and look for the device that has "Enclosure" in its name.
Step 3 Note down it's identifier, usually starting with naa....
Step 4 Run this cmd: "esxcli storage core device set --state=off ?d naa.x" but replace naa.x with the your device identifier.
This should eliminate the messages from the vmkernel.log and Cisco IMC Storage log. (CSCuj10535)
XML API
Symptom The configResolveDn xml api request of Cisco Flex Flash related objects will return empty XML responses.
Symptom The fault code F0181 is raised by Cisco IMC when the local disk is removed while the rack server was in use. This fault is visible through Cisco IMC WebUI, CLI and SNMP interfaces. But the same fault is not retrievable through the XMLAPI interface.
BIOS
Symptom During BIOS post, the system hangs when Ctrl+M is pressed to launch the SW RAID configuration utility. This issue is observed when software RAID is enabled on a system which has multiple Emulex PCIE adapters.
Workaround Disable the Option ROMs of the Emulex adapters that are not used for booting using the BIOS setup interface or the BIOS configuration interface from Cisco IMC. (CSCui70228)
Symptom In rare circumstances, the boot order is modified on upgrading from release version 1.5(2) to 1.5(3).
Workaround Set the boot order in the BIOS setup page under boot options. (CSCui64808)
Symptom Systems hangs with CATERR (Catastrophic errors) when memory RAS mode is set to lock step mode. This happens only when DIMMS are mixed with different models.
Workaround No workaround. Do not mix DIMMs of different models when using Lockstep mode. (CSCuj02376)
Broadcom Controller
Symptom Hardware configuration settings of Broadcom 57810 adapters reset after firmware update. This issue happens on all 57810 adapters. The following settings are reset:
Cisco Flexible Flash Controller
Symptom On C220 servers, with 1.5(1f) firmware, the following message is displayed when there is only one SD card:
Workaround Complete the following steps:
Step 1 Remove all the SD cards from the system and reboot Cisco IMC. The error message is no longer displayed.
Step 2 If Cisco IMC reboot is not possible, then insert 2 SD cards in the system (if it has only 1 card), launch Cisco UCS SCU and click Hypervisor SYNC. The error message will no longer be displayed.
Cisco IMC
Symptom UCS C-Series server alarm during Vdisk rebuild cannot be silenced.
Workaround Some customers have had success clearing the event log. Depending upon software version:
To check that all events are cleared:
Other customers have had to disable the alarms until patch is available.
Re-enable after patch is available.
Symptom Cisco IMC CLI and WebUI allow provisioning of usNIC and VMFEX at the same time, but both features are not supported simultaneously.
Workaround Avoid provisioning usNIC and VMFEX at the same time. Use each feature one at the time. (CSCug67576)
Symptom LSI Nytro MegaRAID8110 controllers do not show up in Cisco IMC storage display.
Workaround None. This is intentional behavior. Due to some differences in the display and management of Nytro controllers, their support will be added in a later Cisco IMC release. (CSCuh52878)
Symptom Onboard network devices (LOM) does not get enabled on doing CMOS reset.
Workaround Rebooting the system again one more after CMOS clear will enable the onboard network devices. (CSCue52142)
Cisco usNIC
Symptom Cisco usNIC is not supported when used together with VIC VNtag, iSCSI, or FCoE. This restriction will be lifted in a future release.
BIOS
Symptom UEFI PXE boot is not working in C-series servers.
Workaround None. This feature is currently not supported. (CSCui32274)
LSI
Symptom Creating VDs with Disk Cache set to "Unchanged," Seagate disks will have their Disk Cache enabled. This causes the Seagate-based VD to have faster performance but they are exposed to data loss in the event of a power loss.
Workaround To avoid the potential data loss in power failures, please set the Disk Cache to "Disabled" when creating VDs, especially when Seagate disks are present. (CSCug38260)
Symptom Sometimes in MSM, Logical View for a VD is not shown.
Workaround Use MegaCLI or StorCLI to get full VD properties (CSCuh07307)
Symptom Once a BBU learn cycle is done, MSM Event logs generate the learn cycle complete event as a Warning instead of Information.
Workaround Complete the following steps:
Step 1 Go to Tool -> AlertSettings -> Change Individual Events.
Step 2 Change the severity for event id 153 from Warning to Info. (CSCuh41966)
Symptom BBU Charging Status shows either Charging or Discharging all the time. This could lead to confusion to customers as Charging or Discharging indicate that battery is not in optimal state.
Workaround Customers should use the BBU Status field to determine if the battery is in optimal state. If the BBU status is optimal, it will indicate a good battery. If the BBU status indicates battery needs replacement, then the BBU is bad and needs to be replaced. Charging Status is working as designed and will always indicate Charging or Discharging because Firmware keeps checking the battery charge and ensures that the charge does not fall below the band gap. It charges the battery when it is in lower limits and once it reaches the upper limit of the band, it will stop charging. There can be leakage current which can discharge the battery and bring it back to lower threshold. When this happens, the firmware initiates charging.(CSCui29979)
Symptom Software RAID(SWRAID) setup option is visible in the BIOS setup menu for C24-M3 24 HDD Model Servers even though it is not supported feature in this model.
Workaround By default this option is set to disabled. Do not set this option to enable, as it would cause undefined behavior if set to enabled. (CSCug79131)
Symptom Battery should be declared "bad" when Max error is over 10%.
Workaround If the Max error is over 10% then the BBU should be replaced. (CSCui30440)
Symptom MegaCLi can report that a BBU is both Charging and Discharging at the same time.
BIOS
Symptom When the number of boot enabled devices exceeds the maximum number of bootable devices supported by the server BIOS, the server does not boot.
Workaround Reduce the number of devices on which the boot option is enabled. (CSCuh98808)
Cisco IMC
Symptom SEL has memory entries, but no entries are seen in the fault page. Cisco UCSM fault codes are unavailable for these SEL.
Workaround None. SEL has to be used to decode the memory related events. (CSCud84978)
Symptom When using the CLI with the create-virtual-drive command, entering incorrect parameters for Physical drive slot number, such as like, exit, quit, is not flagged as an error.
Workaround Enter the listed physical drive slot numbers for Virtual drive creation. (CSCuc72251)
Symptom In the CLI, the create-virtual-drive command in the virtual drive scope does not display the largest possible size of the virtual drive being created.
Workaround Use the WebUI to create virtual drives from unused physical drives if a maximum-size VD is desired. (CSCuc98444)
Symptom In the CLI, the create-virtual-drive command accepts non-existent Physical Drive numbers as well as invalid virtual drive size and creates a virtual drive. The show-virtual-drive command lists the virtual drive created with invalid parameters but marks the state of the virtual drive "Offline”.
Workaround Enter valid parameters for all fields like Physical Drive number, Virtual drive size, Cache policy to create a virtual drive with optimal state. The virtual drive created with invalid parameters can be deleted using the delete-virtual-drive command in the CLI. (CSCuc99149)
Symptom Faults to signify physical drive rebuild status are not reported.
Workaround Check the rebuild status using the Cisco IMC's web interface or host-based MSM or MegaCLI interface. (CSCud42692)
Symptom When a RAID controller cannot load its drive configuration, no fault is generated.
Workaround Check manually whether drive configuration has been lost. (CSCue00749)
Symptom Sometimes after carving a new virtual drive out of an existing drive group, the new virtual drive does not show in the list of available virtual drives during a subsequent carve-virtual-drive command. The drive is created.
Workaround Since the new virtual drive is sharing a drive group that already existed, select a previously-created virtual drive to specify that drive group. (CSCue04743)
Symptom On some MegaRAID controllers, a maximum of 16 virtual drives can be created. If the maximum number of virtual drives is created, then one is deleted, neither the WebUI nor pmcli will allow another virtual drive to be created, even though MSM and MegaRAID allow the last drive to again be created.
Workaround Use MSM or MegaCLI to re-create the last virtual drive. (CSCue04815)
Symptom When a physical drive is set as the boot drive via MegaCLI, this change is not picked up by the pmcli or WebUI display of virtual drives: The previously-set boot virtual drive is displayed as the current boot drive. The show detail command in the controller scope does show the correct information, both the PD's deviceID and the fact that the boot drive is now a PD.
Workaround Disregard the "Boot Drive" column in WebUI and pmcli. Refer to the pmcli output of the show detail command in the controller scope. (CSCue49438)
Symptom The bootable virtual drive is displayed in a column in the WebUI virtual drive tab, and in the show virtual-drive output in the controller scope, and show output in the virtual drive scope. Also, in release 1.5(1), the boot drive can be set via both the WebUI and pmcli. But if the boot drive value is changed via MegaCLI, that change is not picked up by the WebUI or pmcli. Note that the MegaCLI's command does succeed and the boot drive is changed, but the WebUI and pmcli do not display the correct value.
Workaround Set the boot drive using the WebUI or pmcli to the value set via MegaCLI. This will synchronize the Cisco IMC with MegaCLI's value. (CSCue58217)
Symptom Sometimes, the Storage Log in the Cisco IMC WebUI and CLI does not show the latest events generated. This usually occurs after Cisco IMC is upgraded to the new version.
Workaround Reboot Cisco IMC only once and this will fix this issue and Storage log will show the latest events generated. (CSCuc94314)
LSI
Symptom RAID CD-ROM Drive appears in the Boot Options. Booting to this option will give blank screen.
Workaround This is an invalid option and is not usable and should be ignored. (CSCud27042)
VIC
Symptom In VIC 1225T, when the system is booted in the 1Gbps mode, the MAC sometimes does not detect the link. PHY seems to detect the link. But the MAC shows a link down error.
Workaround Reset the switch port. Both Phy and Mac will show the link as up after a switch port reset. (CSCue56950)
Cisco IMC
Symptom LSI storage controllers with external ports (-8e cards) do not show up in Cisco IMC local storage management.
Workaround There is no workaround. (CSCud18756)
Symptom Repeated VIC adapter resets using Cisco IMC Web UI or CLI adapter-reset can cause VIC card to hang.
Workaround Do not reset the VIC adapter unless necessary. It should normally never be necessary to reset the VIC adapter manually. (CSCuc83809)
LSI
Symptom The LSI controller CLI Application MegaCli does not properly work under Windows Power Shell. A failure message is displayed when creating virtual drives for RAID levels 1,5,10,50 and 60.
Workaround MegaCli is not supported in Power Shell. Use the command prompt on Windows for running all MegaCli commands and options. (CSCub49559)
Cisco IMC
Symptom The SEL event is not logged in the OS Watchdog timer expiration.
Symptom Cisco IMC storage view of LSI 9260 card occasionally reports 0 Cache Memory size.
Workaround None. You can use host-based MSM tools to corroborate data. (CSCtn08982)
Symptom When updating Cisco IMC firmware through TFTP, if the image file is corrupted, the update status indicator is the same as if the file does not exist.
Workaround Be aware that this error message can actually indicate either of the above conditions and should make sure that the file both the exists, and is a valid firmware image for the Cisco IMC being upgraded. (CSCti17492)
Symptom The following symptoms are observed in RHEL 6.3
- OS Kernel Panic.
- FC Target not visible to the OS.
- SAN OS installation fails to recognize the FC Target.
Workaround Follow these steps:
Check and verify the switch configuration to ensure that only 1 VSAN and VLAN is configured on the FCOE interface. Verify Virtual Interface Information (FCOE interface) to check that only 1 VSAN is allowed.
Run the following command to check if multiple VSAN is configured:
Trunk vsans (admin allowed and active) (n-m)
Run the following commands to change the Virtual Interface Configuration to allow only 1 Vsan.
Verify the bound interface configuration.
Bound interface is <bound_interface_name>
Run the following commands to change the Bound Interface Configuration to allow only 1 VLAN.
LSI
Symptom The system hangs when you type Exit in the EFI shell.
Workaround Hard reset the server to recover from system hang. (CSCtx64756)
Cisco IMC
Symptom The KVM viewer version does not display the FCS version, that is, 2.0.0.27. This means the client machine has not downloaded the new.jar file for the KVM/vMedia client and the old client is getting executed. This issue is seen when you use KVM with the old Cisco IMC firmware and then upgraded the Cisco IMC. To check the KVM viewer version, invoke KVM and go to Help >About KVM Viewer. The KVM Viewer version should be 2.0.0.27 for Release 1.4(4a).
Workaround To resolve this issue delete the Java temporary cached files and invoke KVM from Cisco IMC GUI. The Java Control Panel app (javacpl.exe) is in the bin directory of the Java JRE installation.
For Windows, go to in c:\Program Files\Java\<JRE VERSION>\bin and delete the cached Cisco Virtual KVM Console application and re-launch remote presence.
