Disaster recovery
HP X5500 Storage Gateway for Linux servers in the cluster are highly reliable. The hardware has
redundant components that should keep a server running, in most scenarios. If you must replace a
server or re-image the operating system and software, a Quick Restore DVD is included with the
product for this purpose.
CAUTION:
The Quick Restore DVD restores a cluster node to its original factory state. This is a destructive process
that completely erases all of the data on local hard drives.
Re-image the cluster node
To re-image a node, complete the following steps:
1. Install the Quick Restore DVD in the DL360's DVD ROM drive.
2. Reboot the system.
3. The "Quick Restore DVD" option loads the required setup for restoring the factory image. When
the prompt is displayed, “Do you want to restore image? (y/n)”, enter Y to restore the image or
N to cancel it.
NOTE:
This completely erases all of the data on both mirrored hard drives.
When the restore process is finished, the DVD ejects, and the system automatically reboots. You can
now perform a node state restore, if you performed a system state backup previously.
