Apply the patch to one node in the cluster at a time. When applying a non-rebooting patch, you do not need to first shut down the node receiving the patch.
Before applying the patch, check the Sun Cluster product web page for any special pre- or post-installation instructions.
If this is a data service patch, switch over the affected data service(s) from the node that you will be patching to a backup node, before applying the patch.
# scswitch -z -g resource-group[,...] -h node[,...] |
Apply the patch on a single node.
If you switched a data service in Step 2, perform the patch installation on the node from which you switched the data service.
# patchadd -M patch-dir patch-id |
Specifies the directory location of the patch.
Specifies the patch number of a given patch.
Verify that the patch has been installed successfully.
# showrev -p | grep patch-id |
Verify that the patch works, and that the node and cluster are operating normally.
If you switched a data service to a backup node in Step 2, you can now switch it back to the original primary node.
Repeat Step 3 through Step 5 for the remaining cluster nodes.
# patchadd -M /tmp/patches 234567-05 ... # showrev -p | grep 234567-05 |
