Reason for the lock failure:
Because of the sudden ungraceful shutdown of the database, file locks on data files were not released by the NFS server (ZFS SA in this case). NFS server held on to the file locks even after the NFS client (DB server node in this example) was restarted. Due to this, Oracle RDBMS is not able to lock those data files residing on NFS server (ZFS SA). As a result, database instance was failed to start up in exclusive mode.

This script will make an export of all running machines in a XEN Source host and will be saved as .xva file.
This script mount a NFS shared resource (you can comment that part and use a local folder only).
This is the script I use for backing up my running Virtual machines each week.
