Managing the Chassis

This chapter includes the following sections:

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 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 reacknowledge the chassis. If you reacknowledge the chassis too soon, the pinning of server traffic from the chassis may not be updated with the changes to the port that you enabled or disabled.

Procedure
      Command or Action Purpose
    Step 1 UCS-A# acknowledge chassis chassis-num  

    Acknowledges the specified chassis.

     
    Step 2 UCS-A# commit-buffer  

    Commits the transaction to the system configuration.

     

    The following example acknowledges chassis 2 and commits the transaction:

    UCS-A# acknowledge chassis 2
    UCS-A* # commit-buffer
    UCS-A # 
    

    Decommissioning a Chassis

    Procedure
        Command or Action Purpose
      Step 1 UCS-A# decommission chassis chassis-num  

      Decommissions the specified chassis.

       
      Step 2 UCS-A# commit-buffer  

      Commits the transaction to the system configuration.

       

      The decommission may take several minutes to complete.

      The following example decommissions chassis 2 and commits the transaction:

      UCS-A# decommission chassis 2
      UCS-A* # commit-buffer
      UCS-A # show chassis
      
      Chassis:
          Chassis    Overall Status           Admin State
          ---------- ------------------------ -----------
                   1 Operable                 Acknowledged
                   2 Accessibility Problem    Decommission
      UCS-A # 
      

      Removing a Chassis

      Before You Begin

      Physically remove the chassis before performing the following procedure.

      Procedure
          Command or Action Purpose
        Step 1 UCS-A# remove chassis chassis-num  

        Removes the specified chassis.

         
        Step 2 UCS-A# commit-buffer  

        Commits the transaction to the system configuration.

         

        The removal may take several minutes to complete.

        The following example removes chassis 2 and commits the transaction:

        UCS-A# remove chassis 2
        UCS-A* # commit-buffer
        UCS-A # 
        

        Recommissioning a 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.

        Before You Begin

        Collect the following information about the chassis to be recommissioned:

        • Vendor name
        • Model name
        • Serial number
        Procedure
            Command or Action Purpose
          Step 1 UCS-A# recommission chassis vendor-name model-name serial-num  

          Recommissions the specified chassis.

           
          Step 2 UCS-A# commit-buffer  

          Commits the transaction to the system configuration.

           

          The following example recommissions a Cisco UCS 5108 chassis and commits the transaction:

          UCS-A# show chassis
          
          Chassis:
              Chassis    Overall Status           Admin State
              ---------- ------------------------ -----------
                       1 Accessibility Problem    Decommission
          
          UCS-A# recommission chassis "Cisco Systems Inc" "N20-C6508" FOX1252GNNN
          UCS-A* # commit-buffer
          UCS-A # 
          

          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 and then wait for the chassis decommission FSM to complete before proceeding with the renumbering steps.

          Procedure
              Command or Action Purpose
            Step 1 UCS-A# show chassis inventory 

            Displays information about your chassis.

             
            Step 2 Verify that the chassis inventory 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 inventory, decommission those chassis. You must wait until the decommission FSM is complete and the chassis are not listed in the chassis inventory before continuing. This might take several minutes.

            To see which chassis have been decommissioned, issue the show chassis decommissioned command.

             
            Step 3 UCS-A# recommission chassis vendor-name model-name serial-num [chassis-num]  

            Recommissions and renumbers the specified chassis.

             
            Step 4 UCS-A# commit-buffer  

            Commits the transaction to the system configuration.

             

            The following example decommissions two Cisco UCS chassis (chassis 7 and 8), switches their IDs, and commits the transaction:

            UCS-A# show chassis inventory
