Occasionally a Linux boot LUN (disk) may be corrupted to the point where it fails to boot.
If the LUN is on an external disk drive, such as a storage array on the storage area network (SAN), you may be able to repair it by mounting it under a different partition, or use storage array tools to restore a correct image onto the LUN from a backup source.
If the LUN is on the internal disk of the enterprise partition platform (EPP), you can refer to the following topics for some options for repairing or restoring the boot disk.
