Sun Cluster Software Installation Guide for Solaris OS

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.


Note –

If the node has already joined the cluster and is no longer in installation mode (see 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.


  1. Attempt to reinstall the node.

    You can correct certain failed installations 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 an active cluster member, add the node that you intend to uninstall to the cluster node-authentication list.

    Skip this step if you are uninstalling a single-node cluster.


    # /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 System Administration Guide for Solaris OS for procedures.

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

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


    # shutdown -g0 -y -i0
    
  6. 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
      

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


    # cd /
    

  8. Uninstall Sun Cluster software from the node.


    # /usr/cluster/bin/scinstall -r
    

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

  9. 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.
