8 Storage system recovery
This chapter describes how to perform a system recovery. To restore the HP StoreEasy 3000 Storage
system to the factory defaults, see
“Restoring the factory image with a DVD or USB flash device”
.
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.
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.
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:
1.
Click
Start
→
Windows PowerShell
.
The Windows PowerShell window opens.
2.
Enter
diskmgmt.msc
and press
Enter
.
The Disk Management window opens.
3.
Right-click the disk and partition the one for which you want to assign a drive letter and select
Change Drive Letter and Paths
.
Restoring the factory image with a DVD or USB flash device
1.
Do one of the following:
a.
For direct access, insert the System Recovery DVD or a bootable USB flash device
(prepared with a System Recovery image).
b.
For remote management access, connect to the server using iLO from a client PC. Insert
the System Recovery DVD in the client PC or attach a bootable USB flash device that has
