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 instance through Cisco UCS Manager GUI.

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.

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.

Decommissioning a Chassis

This procedure decommissions the chassis and deletes it from the Cisco UCS configuration. The chassis hardware physically remains in the Cisco UCS instance. However, Cisco UCS ignores it and does not list it with the other commissioned 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 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.

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.

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   Right-click the chassis you want to enable and choose Recommission.
Step 6   If Cisco UCS Manager 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.

Toggling the Locator LED

Turning on the Locator LED for a Chassis

Procedure
Step 1   In the Navigation pane, click the Equipment tab.
Step 2   On the Equipment tab, expand Equipment > Chassis.
Step 3   Click the chassis that you need to locate.
Step 4   In the Work pane, click the General tab.
Step 5   In the Actions area, click Turn on Locator LED.

This action is not available if the locator LED is already turned on.

The LED on the chassis starts flashing.

Turning off the Locator LED for 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 for which you want to turn off the locator LED.
Step 4   In the Work pane, click the General tab.
Step 5   In the Actions area, click Turn off Locator LED.

This action is not available if the locator LED is already turned off.

The LED on the chassis stops flashing.

Viewing the POST Results for a Chassis

You can view any errors collected during the Power On Self-Test process for all servers and adapters in 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 for which you want to view the POST results.
Step 4   In the Work pane, click the General tab.
Step 5   In the Actions area, click View POST Results.

The POST Results dialog box lists the POST results for each server in the chassis and its adapters.

Step 6   (Optional)Click the link in the Affected Object column to view the properties of that adapter.
Step 7   Click OK to close the POST Results dialog box.
