7 Storage system recovery
This chapter describes how to perform a system recovery. To restore the X5000 G2 to the factory
defaults, see
"Restoring the factory image with a DVD or USB flash device" (page

System Recovery DVD
The X5000 G2 System Recovery DVD enables you to install an image or recover from a catastrophic
failure.
At any time, you may boot from the DVD and restore the server to the factory condition. This enables
you to recover the system if all other means to boot the server fail.
While the recovery process makes every attempt to preserve the existing data volumes, you should
have a backup of your data before recovering the system.
IMPORTANT:
During system recovery, you can replace the existing drives with drives of the same size or larger.
HP recommends that the replacement drives be the same type as the original drives, but it is not
required. However, drives in the same RAID group must all be the same type (you cannot mix drive
types in a RAID group).
If you replace any disk drives and then perform a system recovery, you must ensure that the
replacement drives do not contain a logical drive. Use the Option ROM Configuration for Arrays
(ORCA) utility to delete logical drives. For more information about ORCA, see the Configuring
Arrays on HP Smart Array Controllers Reference Guide, which is available at:
http://www.hp.com/support/manuals
Under servers, select Server Management and then select HP Smart Array Advanced Pack Software
under Server Management Software.
