An uninstall of the Oracle VM Agent on Oracle VM Server for SPARC should only be performed when the Oracle VM Server is no longer assigned to a server pool. This is particularly important if the Oracle VM Server is a member of a clustered server pool. However, if uninstallation is attempted on an Oracle VM Server that is part of a clustered server pool using the ovs-agent-setup unconfigure command, a Lock error may be returned during the process:
... agent.lib.filelock.LockError: Lock file /var/run/ovs-agent/cluster.lock failed: timeout occured. Aborting the uninstallation because there was an error during the unconfiguration of the Oracle VM Agent.
Workaround: Remove the cluster lock file before restarting the uninstall command:
# rm /var/run/ovs-agent/cluster.lock # ovs-agent-setup unconfigure
