How to Uninstall VERITAS Volume Manager Software From a Sun Cluster 2.2 Configuration

If your cluster uses VERITAS Volume Manager (VxVM), perform this procedure on each node of the cluster to uninstall the VxVM software. Existing disk groups are retained and automatically reimported after you have upgraded all software.

To upgrade to Sun Cluster 3.0 12/01 software, you must remove VxVM software and later reinstall it, regardless of whether you have the latest version of VxVM installed.

1. Become superuser on a cluster node.

2. Uninstall VxVM.

   Follow procedures in your VxVM documentation. This process involves the following tasks.

   • Deport all VxVM disk groups. Ensure that disks containing data to be preserved are not used for other purposes during the upgrade.

   • Unencapsulate the root disk, if it is encapsulated.

   • Shut down VxVM.

   • Remove all installed VxVM software packages.

3. Remove the VxVM device namespace.

   # rm -rf /dev/vx

4. Repeat Step 1 through Step 3 on the other cluster node.

5. Upgrade or prepare the Solaris operating environment to support Sun Cluster 3.0 12/01 software.
