Restoring the factory image with a DVD or USB flash device
1. Do one of the following:
a. For direct access, attach the SUV cable (supplied with the System) to the port on the front
of the server blade you want to recover. Connect a monitor and USB mouse to the SUV
cable. Using the remaining USB connector on the SUV cable, connect either a USB DVD
drive (and 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
been prepared with a System Recovery image.
2. Reboot the server blade to either the USB flash device or USB DVD drive.
The system BIOS attempts to boot to the USB device first by default. Watch the monitor output
during the boot as you may need to press a key to boot to the USB media.
NOTE: If directly connected, you may have to change the BIOS settings to ensure proper
boot sequence. If connected remotely, you may have to change some iLO settings to ensure
proper boot sequence.
3. Click Restore Factory Image.
The recovery process completes with minimal user intervention required. The server automatically
reboots more than once.
IMPORTANT: Do not interrupt the recovery process.
When the recovery process completes, the Set Up Windows wizard appears. The next steps
depend on whether you are recovering both server blades (see “Recovering both servers”
(page 85)) or recovering a single blade (see “Recovering a single server” (page 85)).
4. Remove the directly connected DVD or flash device (or remotely connected iLO virtual DVD
or flash device) from the server.
Using a USB flash drive for storage system recovery
If you create a backup copy of the System Recovery DVD using a USB flash drive, you can also
use it to restore the system.
To create a system recovery USB flash drive:
1. Obtain a blank 4 GB or larger USB flash drive.
2. Insert the USB flash device into your workstation or laptop.
3. Open an elevated command prompt with Administrator privileges.
4. At the command prompt, enter diskpart.
5. At the diskpart prompt, enter list disk.
6. Identify the disk number that corresponds to the flash drive. This is typically the last disk listed.
7. Enter sel disk <USB drive number> (for example, sel disk 4).
8. Enter clean. This deletes everything from the USB flash device, so ensure that you have the
proper disk selected.
9. Enter create par primary.
10. Enter sel par 1.
11. Enter format fs=fat32 quick.
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.
