How to Apply a Non-Rebooting Sun Cluster Patch

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.

Steps

1. Before applying the patch, check the Sun Cluster product web page for any special pre- or post-installation 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.
