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, perform this procedure to reconfigure the transport adapters or the private-network address.

If the node has already joined the cluster and is no longer in installation mode, as described in Step 2 of How to Verify the Quorum Configuration and Installation Mode, 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 System Administration Guide for Solaris OS.

Before You Begin

Attempt to reinstall the node. You can correct certain failed installations by repeating Sun Cluster software installation on the node.

Steps

1. Add to the cluster's node-authentication list the node that you intend to uninstall.

   If you are uninstalling a single-node cluster, skip to Step 2.

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

   2. Specify the name of the node to add to the 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

      You can also use the scsetup(1M) utility to perform this task. See How to Add a Node to the Authorized Node List in Sun Cluster System Administration Guide for Solaris OS for procedures.

2. Become superuser on the node that you intend to uninstall.

3. Shut down the node that you intend to uninstall.

   # shutdown -g0 -y -i0

4. Reboot the node into noncluster mode.

   • On SPARC based systems, do the following:

     ok boot -x

   • On x86 based systems, do the following:

     <<< Current Boot Parameters >>> Boot path: /pci@0,0/pci-ide@7,1/ata@1/cmdk@0,0:b Boot args: Type b [file-name] [boot-flags] <ENTER> to boot with options or i <ENTER> to enter boot interpreter or <ENTER> to boot with defaults <<< timeout in 5 seconds >>> Select (b)oot or (i)nterpreter: b -x

5. Change to a directory, such as the root (/) directory, that does not contain any files that are delivered by the Sun Cluster packages.

   # cd /

6. Uninstall Sun Cluster software from the node.

   # /usr/cluster/bin/scinstall -r

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

7. Reinstall and reconfigure 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.
