Disaster Recovery Using a USB Flash Drive
A USB flash drive can be loaded with the necessary files to recover a failed switch. This can be used if the
image files on the switch become corrupted, deleted, or the switch is unable to boot 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 6860/certified on the USB flash drive with the backup system and
configuration files.
2 Copy the Urescue.img file to the root directory on the USB flash drive.
3 Connect the USB flash drive to the switch and reboot. The switch will automatically stop and display
the option to perform a disaster recovery.
4 Enter the ‘run rescue’ command from miniboot/uboot and follow the recovery prompts.
Once complete, the switch will reboot and be operational again.
