Recovering an SSM After Replacing Corrupted CompactFlash Memory
In Cisco MDS SAN-OS Release 2.1(2) and later, you use the CompactFlash memory (modflash:) on the
SSM to store the SSI image. If the modflash: on the SSM is replaced, the SSM might not initialize. To
recover the SSM, follow these steps:
Log into the switch through the console port, an SSH session, or a Telnet session.
Step 1
Display the values assigned to the SSI image boot variable for each module and note the values for later

Module 4
ssi variable = modflash://4-1/m9000-ek9-ssi-mz.2.1.2.bin
Step 3
Clear the values assigned to the SSI image boot variable.

If you replace a supervisor module in a switch with active and standby supervisors, no action is
required because the boot image is automatically synchronized to the new supervisor module.
If you replace a supervisor module in a switch with no standby supervisor, you need to reimplement
the configuration on the new supervisor.

The SSI boot variable must reference the correct SSI boot image, otherwise the SSM fails to
initialize. If you do not correctly set the SSI boot variable, the SSM remains in the
power-down state after attempting to initialize three times.
