Performing a Cluster-Wide Recovery

This section describes how to perform a complete cluster recovery, including

reinstalling the operating system on all nodes in the cluster.

How to Perform a Cluster-Wide Recovery

To recover an entire cluster, perform the following tasks:

• “Task1: Install the Software” on page 154

• “Task 2: Restore the Cluster Database” on page 154

• “Task 3: Start the Cluster” on page 155

• “Task 4: Restore the Data” on page 156

Task1: Install the Software

To install the software:

1. Install the operating system and cluster software on each node.

2. Install the NetWorker software as required within the HP-UX

MC/ServiceGuard cluster environment. For detailed instructions, refer to

the Legato NetWorker Installation Guide, HP-UX Version.

Task 2: Restore the Cluster Database

1. Select any node in the cluster and run the NetWorker server and client

software on that node.

2. Re-create the cluster configuration and the NetWorker software

configuration and control files. The default location for the cluster

configuration file is /etc/cmcluster and the default directory for the

NetWorker configuration and control files is /etc/cmcluster/NetWorker.

• If you know where the latest save sets are located, use the scanner

command to restore the configuration files:

# scanner -S saveset_id device_path | uasm -i y -rv

where device_path is the path to the tape device.

• If you do not know the save set ID, use the scanner device_path

command to determine the saveset ID, as follows:

# scanner device_path > /tmp/savefile 2>&1
