14 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. Connect a keyboard to the keyboard connector.
2. Connect a monitor to the video connector.
3. Insert the VLS Quick Restore CD into the CD-ROM or DVD-CD drive.
The VLS Quick Restore CD auto starts.
4. 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.
5. 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:
The warm failover process automatically restores the node to its previous configuration including the
serial numbers, front-end Fibre Channel WWPNs, virtual device configuration, and licenses. No
reconfiguration is required. See Warm Failover.
Restoring a VLS running firmware version 2.x or 3.1:
1. Restore the configuration settings. See Restoring the Configuration Settings.
