How to Prepare the Cluster for Patch Installation

1. Ensure that the cluster is functioning properly.

   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 a node of the cluster.

3. Remove all application resource groups from protection groups.

   This step ensures that resource groups are not stopped when you later stop the protection groups.

   # geopg remove-resource-group resourcegroup protectiongroup

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

4. Perform the preceding steps on all clusters that have a partnership with this cluster.

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

   # geopg stop -e local protectiongroup

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

6. Stop the Sun Cluster Geographic Edition infrastructure.

   # geoadm stop

   Shutting down the infrastructure ensures that a patch installation on one cluster does not affect the other cluster in the partnership.

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

7. On each node, stop the common agent container.

   # /usr/sbin/cacaoadm stop

   ---

   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.
