How to Upgrade Quorum Server Software

If the cluster uses a quorum server, upgrade the Quorum Server software on the quorum server before you upgrade the cluster.

If more than one cluster uses the quorum server, perform these steps for each of those clusters.

Perform all steps as superuser on the cluster and on the quorum server.

1. If the cluster has two nodes and the quorum server is the cluster's only quorum device, temporarily add a second quorum device.

   See Adding a Quorum Device in Sun Cluster System Administration Guide for Solaris OS.

   If you add another quorum server as a temporary quorum device, the quorum server can run the same software version as the quorum server that you are upgrading, or it can run the 3.2 11/09 version of Quorum Server software.

2. Unconfigure the quorum server from each cluster that uses the quorum server.

   phys-schost# clquorum remove quorumserver

3. From the quorum server to upgrade, verify that the quorum server no longer serves any cluster.

   quorumserver# clquorumserver show +

   If the output shows any cluster is still served by the quorum server, unconfigure the quorum server from that cluster. Then repeat this step to confirm that the quorum server is no longer configured with any cluster.

   Note –

   If you have unconfigured the quorum server from a cluster but the clquorumserver show command still reports that the quorum server is serving that cluster, the command might be reporting stale configuration information. See Cleaning Up Stale Quorum Server Cluster Information in Sun Cluster System Administration Guide for Solaris OS.

4. From the quorum server to upgrade, halt all quorum server instances.

   quorumserver# clquorumserver stop +

5. Uninstall the Quorum Server software from the quorum server to upgrade.

   1. Navigate to the directory where the uninstaller is located.

      quorumserver# cd /var/sadm/prod/SUNWentsysver

      ver

      The version of Java Enterprise System that is installed on your system.

   2. Start the uninstallation wizard.

      quorumserver# ./uninstall

   3. Follow instructions on the screen to uninstall the Quorum Server software from the quorum-server host computer.

      After removal is finished, you can view any available log. See Chapter 8, Uninstalling, in Sun Java Enterprise System 5 Update 1 Installation Guide for UNIX for additional information about using the uninstall program.

   4. (Optional) Clean up or remove the quorum server directories.

      By default, this directory is /var/scqsd.

6. Install the Sun Cluster 3.2 11/09 Quorum Server software, reconfigure the quorum server, and start the quorum server daemon.

   Follow the steps in How to Install and Configure Quorum Server Software in Sun Cluster Software Installation Guide for Solaris OS for installing the Quorum Server software.

7. From a cluster node, configure the upgraded quorum server as a quorum device.

   Follow the steps in How to Configure Quorum Devices in Sun Cluster Software Installation Guide for Solaris OS.

8. If you configured a temporary quorum device, unconfigure it.

   phys-schost# clquorum remove tempquorum
