Deleting the Cluster Configuration
You can delete a cluster configuration by means of the cmdeleteconf command. The
command prompts for a verification before deleting the files unless you use the -f option.
You can delete the configuration only when the cluster is down. The action removes the
binary configuration file from all the nodes in the cluster and resets all cluster-aware
volume groups to be no longer cluster-aware.
NOTE: The cmdeleteconf command removes only the cluster binary file $SGCONF/
cmclconfig. It does not remove any other files from the $SGCONF directory.
Although the cluster must be halted, all nodes in the cluster should be powered up and
accessible before you use the cmdeleteconf command. If a node is powered down,
power it up and allow it to boot. If a node is inaccessible, you will see a list of inaccessible
nodes and the following message:
Checking current status
cmdeleteconf: Unable to reach node lptest1.
WARNING: Once the unreachable node is up, cmdeleteconf
should be executed on the node to remove the configuration.
Delete cluster lpcluster anyway (y/[n])?
Reply Yes to remove the configuration. Later, if the inaccessible node becomes available,
run cmdeleteconf on that node to remove the configuration file.
