15 Disaster Recovery; Recovering From Operating System Failure - HP StorageWorks 9000 - Virtual Library System User Manual

15 Disaster Recovery

This section details the VLS disaster recovery procedures. It includes recovering from operating system
failures, disk array failures, and node failures.

Recovering from Operating System Failure

Re-install the operating system if it becomes corrupted or is lost as a result of node RAID volume failure.
CAUTION:
Only install the VLS operating system on the node hard drives. Installing any other operating system
on the node hard drives voids the warranty.
NOTE:
The VLS operating system contains all the hardware device drivers, firmware, and utilities required
to operate the VLS.
To re-install the operating system:
1. When restoring a primary node, power down all of the secondary nodes.
2. Connect a keyboard to the keyboard connector.
3. Connect a monitor to the video connector.
4. Insert the VLS Quick Restore CD into the CD-ROM or DVD-CD drive.
The VLS Quick Restore CD auto starts.
5. Press R on the keyboard to start the re-installation.
The re-installation takes 30 minutes or less to complete. The screen may freeze during the last
10 minutes of the re-installation. This is normal.
The VLS Quick Restore CD is ejected and the system reboots when the re-installation is complete.
6. Restore the VLS. Systems running VLS firmware version 3.2 restore differently from systems running
versions 2.x or 3.1. See below.
Restoring a VLS running firmware version 3.2:
1. When restoring a primary node, power up the secondary nodes once the primary node fully
reboots.
2. When restoring a primary node, set it as the master node in Command View VLS. See
