Managing the Chassis

This chapter includes the following sections:

Chassis Management in Cisco UCS Manager GUI

You can manage and monitor all chassis in a Cisco UCS domain through Cisco UCS Manager GUI.

Guidelines for Removing and Decommissioning Chassis

Consider the following guidelines when deciding whether to remove or decommission a chassis using Cisco UCS Manager:

Decommissioning a Chassis

Decommissioning is performed when a chassis is physically present and connected but you want to temporarily remove it from the Cisco UCS Manager configuration. Because it is expected that a decommissioned chassis will be eventually recommissioned, a portion of the chassis' information is retained by Cisco UCS Manager for future use.

Removing a Chassis

Removing is performed when you physically remove a chassis from the system. Once the physical removal of the chassis is completed, the configuration for that chassis can be removed in Cisco UCS Manager.


Note

You cannot remove a chassis from Cisco UCS Manager if it is physically present and connected.

If you need to add a removed chassis back to the configuration, it must be reconnected and then rediscovered. During rediscovery Cisco UCS Manager will assign the chassis a new ID that may be different from ID that it held before.

Acknowledging a Chassis

Perform the following procedure if you increase or decrease the number of links that connect the chassis to the fabric interconnect. Acknowledging the chassis ensures that Cisco UCS Manager is aware of the change in the number of links and that traffics flows along all available links.

After you enable or disable a port on a fabric interconnect, wait for at least 1 minute before you re-acknowledge the chassis. If you re-acknowledge the chassis too soon, the pinning of server traffic from the chassis might not get updated with the changes to the port that you enabled or disabled.

Procedure
    Step 1   In the Navigation pane, click Equipment.
    Step 2   Expand Equipment > Chassis.
    Step 3   Choose the chassis that you want to acknowledge.
    Step 4   In the Work pane, click the General tab.
    Step 5   In the Actions area, click Acknowledge Chassis.
    Step 6   If Cisco UCS Manager displays a confirmation dialog box, click Yes.

    Cisco UCS Manager disconnects the chassis and then rebuilds the connections between the chassis and the fabric interconnect or fabric interconnects in the system.

    Decommissioning a Chassis

    Procedure
      Step 1   In the Navigation pane, click Equipment.
      Step 2   Expand Equipment > Chassis.
      Step 3   Choose the chassis that you want to decommission.
      Step 4   In the Work pane, click the General tab.
      Step 5   In the Actions area, click Decommission Chassis.
      Step 6   If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

      The decommission may take several minutes to complete. After the chassis has been removed from the configuration, Cisco UCS Manager adds the chassis to the Decommissioned tab.

      Removing a Chassis

      Before You Begin

      Physically remove the chassis before performing the following procedure.

      Procedure
        Step 1   In the Navigation pane, click Equipment.
        Step 2   Expand Equipment > Chassis.
        Step 3   Choose the chassis that you want to remove.
        Step 4   In the Work pane, click the General tab.
        Step 5   In the Actions area, click Remove Chassis.
        Step 6   If Cisco UCS Manager displays a confirmation dialog box, click Yes.

        The removal may take several minutes to complete.

        Recommissioning a Single Chassis

        This procedure returns the chassis to the configuration and applies the chassis discovery policy to the chassis. After this procedure, you can access the chassis and any servers in it.

        Procedure
          Step 1   In the Navigation pane, click Equipment.
          Step 2   In the Equipment tab, expand the Equipment node.
          Step 3   Click the Chassis node.
          Step 4   In the Work pane, click the Decommissioned tab.
          Step 5   For the chassis that you want to recommission, do the following:
          1. Right-click the chassis and choose Re-commission Chassis.
          2. In the Chassis ID field of the Re-commission Chassis dialog box, type or use the arrows to choose the ID that you want to assign to the chassis
          3. Click OK.
          Step 6   If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

          This procedure may take several minutes to complete. After the chassis has been recommissioned, Cisco UCS Manager runs the chassis discovery policy and adds the chassis to the list in the Navigation pane.

          Recommissioning Multiple Chassis

          This procedure returns the chassis to the configuration and applies the chassis discovery policy to the chassis. After this procedure, you can access the chassis and any servers in it.


          Note

          You cannot renumber the chassis when you recommission multiple chassis at the same time. Cisco UCS Manager assigns the same ID that the chassis had previously.

          Procedure
            Step 1   In the Navigation pane, click Equipment.
            Step 2   In the Equipment tab, expand the Equipment node.
            Step 3   Click the Chassis node.
            Step 4   In the Work pane, click the Decommissioned tab.
            Step 5   In the row for each chassis that you want to recommission, check the Re-commission check box.
            Step 6   Click Save Changes.
            Step 7   If Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

            This procedure may take several minutes to complete. After the chassis has been recommissioned, Cisco UCS Manager runs the chassis discovery policy and adds the chassis to the list in the Navigation pane.

            Renumbering a Chassis


            Note

            You cannot renumber a blade server through Cisco UCS Manager. The ID assigned to a blade server is determined by its physical slot in the chassis. To renumber a blade server, you must physically move the server to a different slot in the chassis.

            Before You Begin

            If you are swapping IDs between chassis, you must first decommission both chassis, then wait for the chassis decommission FSM to complete before proceeding with the renumbering steps.

            Procedure
              Step 1   In the Navigation pane, click Equipment.
              Step 2   Expand Equipment > Chassis.
              Step 3   Verify that the Chassis node does not include the following:

              • The chassis you want to renumber

              • A chassis with the number you want to use

              If either of these chassis are listed in the Chassis node, decommission those chassis. You must wait until the decommission FSM is complete and the chassis are not listed in the Chassis node before continuing. This might take several minutes.

              Step 4   On the Equipment tab, click the Chassis node.
              Step 5   In the Work pane, click the Decommissioned tab.
              Step 6   For the chassis that you want to renumber, do the following:
              1. Right-click the chassis and choose Re-commission Chassis.
              2. In the Chassis ID field of the Re-commission Chassis dialog box, type or use the arrows to choose the ID that you want to assign to the chassis
              3. Click OK
              Step 7   If a confirmation dialog box displays, click Yes.

              Toggling the Locator LED

              Local Disk Locator LED Status

              The local disk locator LED, located on the slot where you insert the local disk, identifies where a specific disk is inserted in a blade or rack server. The locator LED is useful when you need to remove a disk from among many in a server for maintenance.

              You can successfully turn on or off the local disk locator LED when:

              • The server is powered on. When the server is powered off and you try to turn on or off, the locator LED, UCS Manager generates an error.

              • CIMC version is 2.7 or higher.

              • The RAID controller supports the out-of-band (OOB) storage interface.
