Managing the Chassis

This chapter includes the following sections:

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.

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

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
  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

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" "Cisco UCS 5108" FOX1252GNNN
UCS-A* # commit-buffer

Toggling the Locator LED

Turning On the Locator LED for a Chassis

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

Enters chassis mode for the specified chassis.

 
Step 2 UCS-A /chassis # enable locator-led  

Turns on the chassis locator LED.

 
Step 3 UCS-A /chassis # commit-buffer  

Commits the transaction to the system configuration.

 

The following example turns on the locator LED for chassis 2 and commits the transaction:

UCS-A# scope chassis 2
UCS-A /chassis # enable locator-led
UCS-A /chassis* # commit-buffer
UCS-A /chassis #

Turning Off the Locator LED for a Chassis

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

Enters chassis mode for the specified chassis.

 
Step 2 UCS-A /chassis # disable locator-led  

Turns off the chassis locator LED.

 
Step 3 UCS-A /chassis # commit-buffer  

Commits the transaction to the system configuration.

 

The following example turns off the locator LED for chassis 2 and commits the transaction:

UCS-A# scope chassis 2
UCS-A /chassis # disable locator-led
UCS-A /chassis* # commit-buffer
UCS-A /chassis #
