NOTE: If your USB flash drive does not support the FAT32 file system, format the drive as
NTFS instead. Omitting the quick parameter lengthens the format time considerably.
12. Enter active to mark the partition as active.
13. Enter assign letter=<drive letter> to assign a drive letter to the USB drive (for
example, assign letter=U).
14. Enter exit to quit diskpart context commands.
15. Insert the System Recovery DVD into the computer.
16. Using Windows Explorer or a comparable utility, open the DVD so that all contents are visible,
including hidden and system files.
17. Select all of the files (including bootmgr) on the DVD.
18. Copy all of the selected files to the root of the USB flash drive.
Recovering both servers
If both server blades are being recovered, the process is similar to configuring a new HP StoreEasy
5000 Storage delivered from the factory.
NOTE: Although the recovery process restores the HP StoreEasy 5000 Storage to the factory
version, it does not restore the EMU and iLO address configuration to the factory defaults. The
EMU and iLO address configuration will be the same as it was prior to system recovery.
For each server, follow the steps in “Restoring the factory image with a DVD or USB flash device”
(page 137). Stop when the server is displaying the Set Up Windows wizard. Once both servers are
displaying the Set Up Windows wizard, see “Set up Windows and discover the second node
(page 24), and follow the steps provided. When you run the Create Witness Disk wizard as part
of the Initial Configuration Tasks, the wizard may indicate that a witness disk already exists. The
existing witness disk can be used. The wizard may also discover other LUNs on the shared storage
as well. These LUNs will likely be from a previous cluster on the HP StoreEasy 5000 Storage.
Decide if you want to keep these LUNs and add them to the new cluster later. If you do not want
to keep the existing LUNs, you may select them for deletion in the Create Witness Disk wizard.
Recovering a single server
If only one of the two server blades is being recovered, the process is slightly more involved because
you want to join the recovered server to an existing Windows failover cluster. If you do not have
a functional (containing at least one node) Windows failover cluster, follow the procedure for
“Recovering both servers” (page 138).
The following procedure describes how to re-image one of the server blades of the HP StoreEasy
5000 Storage, and then rejoin the server to the Windows failover cluster:
1. Follow the steps in “Restoring the factory image with a DVD or USB flash device” (page 137).
2. When the Set Up Windows wizard appears, select your desired language, regional settings,
keyboard layout, and accept the EULA. After completing the wizard, an attempt is made to
discover the second node. The attempt fails and the following error message displays.
