Disaster Recovery Using a USB Flash Drive

A USB flash drive can be loaded with the necessary files to recover a failed CMM. This can be used if the
image files on the CMM become corrupted, deleted, or the switch is unable to boot from the CMM for
other reasons. Perform the following steps to run Disaster Recovery:
Note: It's recommended to prepare the USB flash drive prior to needing it for disaster recovery.
1
Create the directory structure 10000/certified and 10000/working on the USB flash drive with the
backup system and configuration files.
2
Copy the Rrescue.img file to the root directory on the USB flash drive.
3
Connect the USB flash drive to the CMM and reboot. The switch will automatically stop and display
the option to perform a disaster recovery.
4
Enter the 'run rescue' command and follow the recovery prompts.
Once complete, the CMM will reboot and be operational again.
