Disaster Recovery Using USB

The switch can be configured to boot from the USB flash drive. 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. The
following is an example for an OmniSwitch 6250:
1 It is recommended to prepare the USB flash drive prior to needing it for disaster recovery.
2 Create a directory named 6250/certified and 6250/working on the USB flash drive with all the proper
backup system and configuration files.
3 Connect the USB flash drive to the CMM. The flash is reformated and the images are copied to the
related /flash/6250/certified (or /flash/6450/certified) directory of the CMM and the switch reboots from
the certified directory.
4 Now that the switch has been recovered it can be reconfigured as needed.
Note: The OmniSwitch must have a properly working 6.6.4 version of uboot/miniboot to support the
Disaster Recovery feature.
Note: If a backup boot.cfg file is on the USB flash drive it is copied along with the image files and can be
used to recover the switch configuration.
