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 Configuring Primary Node 0. (The final step of setting the IP address and other public network configurations is not necessary.)

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:

When restoring a primary node, power down all of the secondary nodes.

Connect a keyboard to the keyboard connector.

Connect a monitor to the video connector.

Insert the VLS Quick Restore CD into the CD-ROM or DVD-CD drive.

The VLS Quick Restore CD auto starts.

Press

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.

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:

When restoring a primary node, power up the secondary nodes once the primary node fully

reboots.

When restoring a primary node, set it as the master node in Command View VLS. See

Configuring

Primary Node 0

. (The final step of setting the IP address and other public network configurations

is not necessary.)
