Disaster Recovery for CMM Software Upgrades
Disaster Recovery for CMM Software Upgrades
Note Disaster recovery is supported only on systems that are using Catalyst operating system software on the
supervisor engine.
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 copy a new image to the supervisor engine Flash memory,
download the image from the supervisor engine to the CMM bootflash, and 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.
These sections provide disaster recovery procedures:
• Disaster Recovery for Supervisor Engine 1 and Supervisor Engine 2, page 29
• Disaster Recovery for Supervisor Engine 720, page 30
Tip If the CMM image fails to load properly, a crash information file is generated and then saved in the CMM
bootflash.
Disaster Recovery for Supervisor Engine 1 and Supervisor Engine 2
For systems that use 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 18 for removal procedures.
Step 2 Enter the copy tftp [device] command to copy the golden image to the supervisor engine Flash memory
where [device] can be either bootflash or slot0.
Step 3 Enter the set filename-alias slot0:ws-svc-cmm [device]:[golden-image] command to translate the file
name of the downloaded file. The [golden-image] is the file to be downloaded, and the [device] can be
either bootflash or slot0. For example, the set filename-alias slot0:ws-svc-cmm bootflash:abc
command sets the file named abc in bootflash to be downloaded.
Step 4 Enter the set module power down mod pm_option command to power down the CMM. Set the power
management bits (pm_option) to 10 if the supervisor engine is in slot 1. Set the power management bits
to 11 if the supervisor engine is in slot 2.
