How to Prepare the Cluster for Patch Installation

You must complete this procedure on only one node of each cluster.

1. Ensure that the cluster is functioning properly.

   Ensure that Sun Cluster Geographic Edition is running properly.

   # geoadm status

   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.

   Check the volume manager status.

2. On a node of the cluster, become root.

   % su

3. Remove all application resource groups from protection groups.

   Highly available applications do not have downtime during the Sun Cluster Geographic Edition software patch installation.

   # geopg remove-resource-group resourcegroup protectiongroupname

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

4. Stop all protection groups that are active on the cluster.

   # geopg stop protectiongroupname -e local | global

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

5. Stop the Sun Cluster Geographic Edition infrastructure.

   # geoadm stop

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