Sun Cluster Geographic Edition System Administration Guide

ProcedureHow to Install Patches on a Sun Cluster Geographic Edition System

Perform this procedure on all nodes of the cluster.

Patch the secondary cluster before you patch the primary cluster, to permit testing.

Before You Begin

Perform the following tasks:

  1. Ensure that all the nodes are online and part of the cluster.

    To view the current status of the cluster, run the following command from any node:

    % cluster status

    See the cluster(1CL) man page for more information.

    Search the /var/adm/messages log on the same node for unresolved error messages or warning messages.

  2. Become superuser on each node.

  3. On each node, install any necessary patches to support Sun Cluster Geographic Edition software by using the patchadd command.

    If you are applying Sun Cluster patches, use the Sun Cluster methods on both clusters.

  4. After you have installed all required patches on all nodes of the cluster, on each node start the common agent container.

    # /usr/sbin/cacaoadm start

    Note –

    You must use common agent container 2, which is located in the /usr/sbin directory. Use the /usr/sbin/cacaoadm -V command to check which version of common agent container you are using.

  5. On one node, enable Sun Cluster Geographic Edition software.

    # geoadm start
  6. Add all application resource groups that you removed while you were preparing the cluster for a patch installation back to the protection group.

    # geopg add-resource-group resourcegroup protectiongroup

    See the geopg(1M) man page for more information.

  7. Start all the protection groups that you have added.

    # geopg start protectiongroup -e local [-n]

    See the geopg(1M) man page for more information.

Next Steps

After you patch the secondary cluster, perform a sanity test on the Sun Cluster Geographic Edition software, and then repeat this procedure on the primary cluster.
