How to Remove the Sun Cluster 3.2 Core Patch

1. List the resource types on the cluster.

   # clrt list

2. If the list returns SUNW.HAStoragePlus:5, SUNW.ScalDeviceGroup:2, or SUNW.ScalMountPoint:2, you must remove these resource types. For instructions on removing a resource type, see How to Remove a Resource Type in Sun Cluster Data Services Planning and Administration Guide for Solaris OS in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

3. Reboot all nodes of the cluster into noncluster, single user mode.

   For instructions on rebooting cluster nodes into noncluster, single user mode, see How to Boot a Cluster Node in Noncluster Mode in Sun Cluster System Administration Guide for Solaris OS in Sun Cluster System Administration Guide for Solaris OS.

4. Remove the Sun Cluster 3.2 core patch from each node on which you installed the patch.

   # patchrm patch-id

5. Reboot into cluster mode all of the nodes from which you removed the Sun Cluster 3.2 core patch.

   Rebooting all of the nodes from which you removed the Sun Cluster 3.2 core patch before rebooting any unaffected nodes ensures that the cluster is formed with the correct information in the CCR. If all nodes on the cluster were patched with the core patch, you can reboot the nodes into cluster mode in any order.

   For instructions on rebooting nodes into cluster mode, see How to Reboot a Cluster Node in Sun Cluster System Administration Guide for Solaris OS in Sun Cluster System Administration Guide for Solaris OS.

6. Reboot any remaining nodes into cluster mode.
