3.7.0 HP StorageWorks HP Scalable NAS File Serving Software provisioning guide for Oracle HP Scalable NAS (AG513-96013, October 2009)

You will need to determine which NFS server was affected by the outage to know
which Virtual NFS Server to rehost. You may not have access to the /var/lib/
nfs/statd/sm directory on the NFS client to view the IP addresses of the affected
servers. At this point, the lock failure itself should point you to the VNFS host that is
holding the lock. For example, if you try to startup your Oracle database and you
get a error indicating failure to obtain the locks, you will need to rehost the Virtual
NFS Server used for $ORACLE_HOME and those used for your Oracle datafiles. In
the case of Virtual IP addresses, the NAS Administrator should view the HP Scalable
NAS Management Console to determine which NFS server is the current primary
server for that address. Check your NFS client mount options in /etc/fstab and
any Direct NFS configuration files (oranfstab) for node names or IP addresses.
