7 Storage system recovery
This chapter describes how to perform a system recovery. To restore the HP StoreEasy 5000 Storage
to the factory defaults, see “Restoring the factory image with a DVD or USB flash device (page 137).
To restore the HP StoreEasy 5000 Storage using Windows Recovery Environment, see “Restoring
the system with Windows Recovery Environment” (page 140).
System Recovery DVD
The 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: All data on the original OS logical drive is erased during the recovery process.
This includes share and quota settings, iSCSI target configuration, local user accounts, and other
configuration options.
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:

Using a downloaded version of the System Recovery DVD
If you have downloaded the System Recovery DVD image from the HP website and the version is
newer than the DVD shipped with the product, you must verify that the firmware versions of all
hardware components are current after completing the system recovery. The firmware for each
hardware component is not automatically updated to the latest version after a system recovery.
IMPORTANT: Do not complete any tasks in the Initial Configuration Tasks window until you verify
the firmware versions.
To verify the firmware versions, complete the following steps on each node:
1. Open HP StoreEasy tools by selecting the HP StoreEasy tools shortcut on the desktop.
2. Using HP StoreEasy tools, launch the Firmware Maintenance Tools command prompt and run
the commands.
3. Once the firmware upgrades are complete, open the Initial Configuration Tasks window to
set up the cluster.
Drive letters are not assigned after a restore
When a system that has existing data volumes (non-operating system volumes) is restored using
the System Recovery DVD, the data volumes will not have drive letters assigned to them. This is by
design. The volume labels are retained and can be used to identify the data volumes.
You can assign drive letters to volumes using diskpart.exe or Disk Management.
To use Disk Management:
