How to Uninstall Sun Cluster Software to Correct Installation Problems

Perform this procedure if the installed node cannot join the cluster, or if you need to correct configuration information, for example, the transport adapters.

If the node has already joined the cluster and is no longer in installation mode (see Step 12 of How to Perform Postinstallation Setup), do not perform this procedure. Instead, go to “How to Uninstall Sun Cluster Software From a Cluster Node” in “Adding and Removing a Cluster Node” in Sun Cluster 3.1 10/03 System Administration Guide.

1. Attempt to reinstall the node.

   You can correct certain failed installations simply by repeating Sun Cluster software installation on the node. If you have already tried to reinstall the node without success, proceed to Step 2 to uninstall Sun Cluster software from the node.

2. Become superuser on an active cluster member other than the node that you are uninstalling.

3. From the active cluster member, add the node that you intend to uninstall to the cluster node-authentication list.

   # /usr/cluster/bin/scconf -a -T node=nodename

   -a

   Add

   -T

   Specifies authentication options

   node=nodename

   Specifies the name of the node to add to the authentication list

   Alternately, you can use the scsetup(1M) utility. See “How to Add a Cluster Node to the Authorized Node List” in “Adding and Removing a Cluster Node” in Sun Cluster 3.1 10/03 System Administration Guide for procedures.

4. Become superuser on the node you intend to uninstall.

5. Reboot the node into noncluster mode.

   # shutdown -g0 -y -i0 ok boot -x

6. Uninstall the node.

   Run the scinstall command from a directory that does not contain any files that are delivered by the Sun Cluster packages.

   # cd / # /usr/cluster/bin/scinstall -r

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

7. Reinstall Sun Cluster software on the node.

   Refer to Table 2–1 for the list of all installation tasks and the order in which to perform the tasks.
