Disaster Recovery for Module Software Upgrades
Disaster Recovery for Module Software Upgrades
This section describes how to recover in the event that the CMM software image fails to load properly. If there is a corrupted image in the CMM bootflash, the CMM does not come online and stays at the ROMMON prompt. You will need to perform these steps to replace the corrupted image:
Step 1 Copy a new image to the supervisor engine flash memory.
Step 2 Download the image from the supervisor engine to the CMM bootflash.
Step 3 Configure the system by using the power management bits to control which image is booted when the CMM is reset.
Note The downloaded image must be the same version that was previously operating on the CMM. Failure to perform the disaster recovery with the same image version could result in corrupted port adapters.
Note To successfully perform disaster recovery on the Supervisor Engine 720, you must have the ROMMON version 12.2(1r)T2 on the CMM.
Use Table 8 for configuring the filename aliases and the boot or power management options for different Catalyst 6500 series supervisor engines.

Tip If the CMM image fails to load properly, a crash information file is generated and then saved in the CMM bootflash.
