Reinitializing the Cluster

In rare circumstances, you may want to reinitialize the cluster systems, services, and database. Be sure to back up the cluster database before reinitializing the cluster. See the Section called Backing Up and Restoring the Cluster Database for information.

To completely reinitialize the cluster, follow these steps:

1. Disable all the running cluster services.

2. Stop the cluster daemons on both cluster systems by invoking the cluster stop command located in the System V init directory on both cluster systems. For example:

   /sbin/service cluster stop

3. Install the cluster software on both cluster systems. See the Section called Steps for Installing and Initializing the Cluster Software in Chapter 3 for information.

4. On one cluster system, run the cluconfig utility. When prompted whether to use the existing cluster database, specify no. This will delete any state information and cluster database from the quorum partitions.

5. After cluconfig completes, follow the utility's instruction to run the cluconfig command on the other cluster system. For example:

   /sbin/cluconfig --init=/dev/raw/raw1

6. Start the cluster daemons by invoking the cluster start command located in the System V init directory on both cluster systems. For example:

   /sbin/service cluster start
