Disaster Recovery for Supervisor Engines Running Catalyst Operating System
Software
To perform disaster recovery on systems that use the Catalyst operating system software on the
supervisor engine, perform these steps:
Step 1 Before performing the disaster recovery, remove the port adapters from the CMM.
See the “Removing and Replacing Port Adapters” section on page 19 for removal procedures.
Step 2 Enter the copy tftp [device] command to copy the golden image for the CMM to the supervisor engine
flash memory where [device] can be any flash file system on the supervisor engine.
Step 3 Enter the set filename-alias [alias-name] [device]:[golden-image] command to translate the filename of
the downloaded file.
The [golden-image] is the file to be downloaded, and the [device] can be any flash file system on the
supervisor engine. See Table 8 for configuring the appropriate [alias-name] corresponding to the
supervisor engine type in use.
Step 4 Enter the set module power down [mod] [pm_option] command to power down the CMM.
See Table 8 for configuring the appropriate [pm_option] corresponding to the supervisor engine type in
use.
Step 5 Enter the set poll disable command to disable polling.
Step 6 Enter the set module power up [mod] command to power up the CMM.
When the CMM powers up, disaster recovery is complete.
Step 7 After you complete the disaster recovery, enter the clear filename-alias [alias-name] command to
terminate the filename translation.
Step 8 Set the power management option for the CMM to zero (0).
This step is necessary to prevent the download mechanism from triggering every time that the CMM is
reset.
Step 9 Enter the set poll enable command to enable polling.
