Disaster Recovery
To help you to log on and access system resources after a computer disaster has
occurred, you can restart the system in
safe mode
,
boot from a spare disk
, or use the
Windows
WinPE command shell
.
Safe Mode
You use the Safe Mode startup options to start the system with only the minimal
necessary services. Safe Mode options include Last Known Good Configuration, Safe
Mode, Safe Mode with Networking, and Safe Mode with Command Prompt. For more
information, see Safe Mode startup options in Windows Help.

!
You must disable the Watchdog Timer by disabling boot
monitoring in the BIOS before attempting to boot in Safe
Mode. See the Express5800/320Ma: Software Installation
and Configuration Guide for a description of how to
disable boot monitoring.
Booting From a Spare System Disk
To boot from a spare system hard disk, you need a spare hard disk that was prepared
during your initial system configuration process. Refer to the Express5800/320Ma:
Software Installation and Configuration Guide for information about how to prepare this
hard disk. Typically, you boot from a backup hard disk only to recover from an unlikely
disaster situation where all redundant system disks suffered simultaneous failure.
To boot a system from an RDR boot disk, see
“Booting a System with a Backup RDR
Boot Disk” on page 4-16
.
The following procedure explains how to boot a system from a non-RDR system disk.
To boot from a previously prepared non-RDR spare system disk
1. Shut down the operating system.
2. Physically remove one of the original system disks.
3. Insert the spare system disk into the empty slot created in step
2
.
4. Unlatch the other original system disk.
5. Power up the system.
6. After the system has booted, insert (latch) the original disk that you unlatched in
step
4
