Shutting Down A Fabric Interconnect - Cisco UCS 6400 Series Hardware Installation Manual

Shutting Down a Fabric Interconnect

Shutting Down a Fabric Interconnect
Use the following procedure when you need to replace a single fabric interconnect with the same model of
fabric interconnect.
Use Cisco UCS Manager, either the GUI or the CLI, to perform the software-related tasks mentioned in the
following procedure. For additional information, refer to the Cisco UCS Manager Getting Started Guide, the
Cisco UCS Manager Infrastructure Management Guide, and the instructional videos available at this URL:
http://www.cisco.com/c/en/us/support/servers-unified-computing/ucs-manager/
products-installation-and-configuration-guides-list.html
As a best practice, perform a full configuration backup before replacing the fabric interconnect.
Note
Verify that all vNICs are either redundant or that the fabric failover is enabled.
Procedure
Step 1 Contact Cisco TAC or your Cisco Sales representative to have them transfer the license to the replacement
fabric interconnect.
Step 2 Label the ports and the cables that you using so that you can refer to this information later. The cabling and
port numbering should be same for the replacement fabric interconnect.
Step 3 Log into UCS Manager and verify the state of the A and B fabric interconnects, either UP or DOWN. From
the CLI, enter the show cluster extended-state command. High availability should be running in UCS
Manager, as indicated by HA is READY.
Example:
FI-A# show cluster extended-state
Cluster Id: 0x537d0580bf9911e0-0x8955000decd07984
A: UP, PRIMARY
B: UP, SUBORDINATE
A: memb state UP, lead state PRIMARY, mgmt services state: UP
B: memb state UP, lead state SUBORDINATE, mgmt services state: UP
heartbeat state PRIMARY_OK
INTERNAL NETWORK INTERFACES:
eth1, UP
eth2, UP
HA READY
Detailed state of the device selected for HA storage:
Chassis 1, serial: FOX1344G1R1, state: active
Chassis 2, serial: FOX1318GDKR, state: active
FI-A#
Step 4
Back up the software configuration.
Step 5 Use the fabric evacuation procedure on the subordinate fabric interconnect to ensure there is no data traffic
impact during the hardware replacement.
Step 6 Power down the subordinate fabric interconnect by unplugging it from the power source.
