Configuring SingleConnect

This chapter includes the following sections:

SingleConnect

Cisco UCS Manager supports an option to integrate the C-Series Rack-Mount Server with Cisco UCS Manager using the NC-SI. This option enables Cisco UCS Manager to manage the C-Series Rack-Mount Servers using a single cable for both management traffic and data traffic. When you use the SingleConnect mode, one host facing port on the FEX is sufficient to manage one rack-mount server, instead of the two ports used in the Shared-LOM mode. This allows you to connect more number of rack-mount servers with Cisco UCS Manager for integrated server management. Make sure you have the correct server firmware for integration with Cisco UCS Manager. If not, upgrade your server firmware before integration. See Upgrading the C-Series Server Firmware.

Management Connection Policy and Connection Mode

When establishing physical connections for the C-Series Rack-Mount Server in the Cisco UCS Domain, you must specify the connection mode and management policy in Cisco UCS Manager GUI or Cisco UCS Manager CLI. The management policy is global to all connected C-Series Rack-Mount Servers. The connection mode determines the rack server discovery in Cisco UCS Manager.

You can specify either one of the following connection policies for the rack servers:

  • Auto Acknowledged: This is the recommended and default connection mode for the C-Series Rack-Mount Server. If the connection mode is auto-acknowledged, immediately after establishing the physical connection, Cisco UCS Manager discovers the rack server and starts managing the server based on the specified management policy.

  • User Acknowledged: If the connection mode is user-acknowledged, after establishing the physical connection, you must manually acknowledge the connection and specify the connection mode in the Cisco UCS Manager GUI or Cisco UCS Manager CLI to begin the discovery. Cisco UCS Manager does not begin the C-Series Rack-Mount Server discovery until you specify the connection mode. See Manually Acknowledging Connection Mode - GUI or Manually Acknowledging Connection Mode - CLI for detailed procedure.


Note

When rack servers are discovered and are managed by Cisco UCS Manager, if you want to change the existing connection mode for one C-Series Rack-Mount Server, you have to decommission the server, re-commission it and specify the new connection mode. Only then Cisco UCS Manager can discover the server in the new connection mode.

Manually Acknowledging Connection Mode

Manually Acknowledging Connection Mode - GUI

If the connection mode is user-acknowledged, after establishing the physical connection, you must manually acknowledge the connection and specify the connection mode in the Cisco UCS Manager GUI to begin the discovery. Cisco UCS Manager does not begin the C-Series Rack-Mount Server discovery until you specify the connection mode.

Procedure

Step 1

Expand Equipment > Rack Mounts > Servers.

Note

 

For Cisco UCS C125 M5 Servers, expand Equipment > Rack Mounts > Enclosures > Rack Enclosure rack_enclosure_number > Servers.

Step 2

Select the Inventory > CIMC tab.

Step 3

Click Configure Management Connection and select Enable.

Step 4

Select Enabled checkbox for State.

Step 5

Click OK.

Manually Acknowledging Connection Mode - CLI

If the connection mode is user-acknowledged, after establishing the physical connection, you must manually acknowledge the connection and specify the connection mode in the Cisco UCS Manager CLI to begin the discovery. Cisco UCS Manager does not begin the C-Series Rack-Mount Server discovery until you specify the connection mode.

Requirements for SingleConnect Integration with Cisco UCS Manager

Requirements for Cluster Setup

You must have the following items to create a single-wire integration for C-Series Rack-Mount Server with Cisco UCS Manager in a cluster setup:

  • A Cisco UCS system that is running Cisco UCS Manager.

  • Any of the C-Series Rack-Mount Servers and corresponding Cisco IMC and UCS Manager release versions listed in Table 1.

  • Two Cisco UCS VIC cards and two Cisco UCS FIs. See Cisco UCS Fabric Interconnect Server Compatibility Matrix for adapter and FI compatibility with your server. To enable SingleConnect for the Cisco UCS Manager integration, you must have a Cisco VIC installed in the specific slot assigned for SingleConnect in the rack server. If the VIC is not in the specific slot, SingleConnect does not work.

Connecting the C-Series Server with Cisco UCS Domain in Cluster Setup

Connecting the C-Series Server with Cisco UCS Domain in Cluster Setup

Before you begin


Important

Ensure that Cisco IMC is set to factory default settings to integrate with Cisco UCS Manager.

Before you connect the server, ensure that the Cisco UCS VIC is installed in the correct slot for integration with Cisco UCS Manager. If the card is not installed in the correct slot, you cannot enable the single-wire management for the server.

Procedure

Step 1

Install the server in the rack. See the Install and Upgrade Guide for the server that you are using. The install guides are available at the following url: Install and Upgrade Guides.

Step 2

Connect the path that carries both data traffic and management traffic to the FEXes:

  1. Connect a supported cable between the adapter card in the server and a port on the FEX that is connected to Fabric A. You can use any port on the FEX.

  2. Connect a supported SFP cable between the adapter card in the server and a port on the FEX that is connected to Fabric B. You can use any port on the FEX.

Step 3

Connect the paths from the FEXes to the FIs.

  1. Connect at least two supported SFP cables between FEX A and two ports on FI A. You can use any ports on FI A, but the ports must be configured as server ports.

  2. Connect at least two supported SFP cables between FEX B and two ports on FI B. You can use any ports on FI B, but the ports must be configured as server ports.

Step 4

Attach a power cord to each power supply in your server, and then attach the power cord to a grounded AC power outlet.

Step 5

Reboot the server.

Managing the Rack-Mount Server in Cisco UCS Manager after Integration

You can manage and monitor all rack-mount servers that have been integrated with a Cisco UCS domain through Cisco UCS Manager. After the integration, you can perform all rack-mount server management tasks only through the service profiles from Cisco UCS Manager GUI or Cisco UCS Manager CLI. The C-Series Rack-Mount Server Cisco IMC is not accessible when you start managing the server with Cisco UCS Manager.

Cisco UCS Manager provides information, errors, and faults for each rack-mount server that was discovered.

For more information on managing C-Series Rack-Mount Servers from Cisco UCS Manager, see the chapter on Managing Rack-Mount Servers in your release specific Cisco UCS Manager Configuration Guide.

Reverting a Server From Cisco UCS Domain Mode to Standalone Mode

When you manage a Cisco UCS C-Series server with Cisco UCS Manager software, a UCS Manager service profile is associated with the server. If you want to revert a C-Series server to standalone mode (so that it can be managed by Cisco IMC software), you must do the following actions in UCS Manager:

Procedure

Step 1

Disassociate the UCS Manager service profile from the server.

Step 2

Remove the connections from the adapter.

Step 3

Manually power on the server.

Step 4

Connect the front panel KVM connection.

Step 5

Press F8 during the boot up.

Step 6

Reset Cisco IMC to factory defaults or stand-alone mode.

Caution

 

If you do not disassociate the service profile from the server, MAC and WWN numbers assigned by Cisco UCS Manager might be kept by the server. This can cause numbering duplication and conflicts with other servers that are managed by Cisco UCS Manager. Also, if you revert a server to standalone mode without disassociating the service profile, any LSI RAID controller may not show as a bootable device in the standalone server, preventing local booting.

Special Considerations for Integrated Servers

When you connect the C-Series servers in Cisco UCS system, make sure to review the following information:

FEX Considerations

Re-acknowledge Attached Servers After a FEX Is Decommissioned/Recommissioned

Whenever you decommission or recommission a Cisco UCS FEX, all the servers that are connected to that FEX must be re-acknowledged in UCS Manager.

Cisco VIC 1455 and 1457 Connectivity

For cluster setup, connect port 1 and 2 to one FEX. Connect port 3 and 4 to another FEX. For non-cluster setup, connect either port 1 and 2 or port 3 and 4 to the FEX.

Cisco VIC 1467 and VIC 15428 Connectivity

For cluster setup, connect port 1 and 2 to one FEX. Connect port 3 and 4 to another FEX. For non-cluster setup, connect either port 1 and 2 or port 3 and 4 to the FEX.
