How to Install Patches

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:

• Ensure that the Solaris OS is installed to support Sun Cluster Geographic Edition software.

  Ensure that the Solaris installation meets the requirements for Sun Cluster Geographic Edition software and any other software that you intend to install on the cluster.

• Ensure that Sun Cluster Geographic Edition software packages are installed on the nodes.

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:

   % scstat

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

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

2. Stop the Common Agent Container.

   # cacaoadm stop

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

3. Install any necessary patches to support Sun Cluster Geographic Edition software by using the patchadd command.

4. Start the Common Agent Container.

   # cacaoadm start

5. After you have installed all required patches on all the nodes of all clusters, enable the Sun Cluster Geographic Edition software.

   # geoadm start

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

   # geopg add-resource-group resourcegroup protectiongroupname

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

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

   # geopg start protectiongroupname -e local | global [-n]

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

8. Verify that Sun Cluster Geographic Edition software, protection groups, device groups, and application resource groups are all the OK state.

   # geoadm status # scstat
