Using the Storage Server Rescue Procedure
Each storage server maintains a copy of the software on the USB stick. Whenever the system configuration changes, the server updates the USB stick. You can use this USB stick to recover the server after a hardware replacement or a software failure. You restore the system when the system disks fail, the operating system has a corrupt file system, or the boot area is damaged. You can replace the disks, cards, CPU, memory, and so forth, and recover the server. You can insert the USB stick in a different server, and it will duplicate the old server.
If only one system disk fails, then use CellCLI commands to recover. In the rare event that both system disks fail simultaneously, then use the rescue functionality provided on the storage server CELLBOOT USB flash drive.
