Problem Summary: When using a ZFS Storage Appliance, during a power failure test, after powering off all the cluster nodes and then powering them back on, the database might not come back online and the whole application might fail. Whenever a power cycle happens, the application might not be available until you manually clear the NFS locks from ZFS Storage Appliance storage.
Workaround: For ZFS Storage Appliance storage (NFS file systems), from the ZFS Storage Appliance GUI, go to maintenance, select workflows and then click Clear Locks (with hostname and IP address).
