NOTE:
The DON’T ERASE logical disk supports the recovery proc ess only and does not host the secondary

the System Installation and Recovery DVD. Be sure to back up your user data, and then use the DVD

Default boot sequence
The BIOS supports the following default boot sequence:
1. DVD-ROM
2. HDD
3. PX E (network boot)
Under normal circumstances, the storage servers boot up from the OS logical drive.
• If the system experiences a drive failure, the drive displays an amber disk failure LED.
• If a single drive failure occurs, it is transparent to the OS.
