@Ontapforrum Yes, it contains Luns. Backups that are getting failed are Storage level. We have scheduled backup of our storage volume every hour. So whenever, backup runs at Commvault level( backup tool) at that time it skips the backup of the volume that we have scheduled at Netapp.
And when backup completes at Commvault level after that volume level backups runs fine.
