You can manage and monitor all chassis in a Cisco UCS instance 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 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
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
On the
Equipment tab, 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 the
Equipment tab.
Step 2
On the
Equipment tab, 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 the
Equipment tab.
Step 2
On the
Equipment tab, 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 the
Equipment tab.
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:
Right-click the chassis and choose Re-commission Chassis.
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
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 the
Equipment tab.
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
Chassis renumbering is supported in Cisco UCS Manager 1.4(2) and later releases. You cannot renumber a chassis in a prior release.
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
Step 1
In the
Navigation pane, click the
Equipment tab.
Step 2
On the
Equipment tab, 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:
Right-click the chassis and choose Re-commission Chassis.
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
Click OK
Step 7
If
Cisco UCS Manager GUI
displays a confirmation dialog box, click
Yes.
