How to Apply a Nonrebooting Sun Cluster Patch

Apply the patch to one node in the cluster at a time. When applying a nonrebooting patch, you do not need to first the node that is receiving the patch.

1. Before applying the patch, check the Sun Cluster product web page for any special preinstallation or postinstallation instructions.

2. Apply the patch on a single node.

   # patchadd -M patch-dir patch-id

   patch-dir

   Specifies the directory location of the patch.

   patch-id

   Specifies the patch number of a given patch.

3. Verify that the patch has been installed successfully.

   # showrev -p | grep patch-id

4. Verify that the patch works, and that the node and cluster are operating normally.

5. Repeat Step 2 through Step 4 for the remaining cluster nodes.

6. Check to see if you need to commit the patch software by using the scversions command.

   # /usr/cluster/bin/scversions

   You will see one of the following results:

   Upgrade commit is needed. Upgrade commit is NOT needed. All versions match.

7. If a commit is needed, commit the patch software.

   # scversions -c

   Note –

   Running scversions will cause one or more CMM reconfigurations, depending on the situation.
