Conflict between NetBackup and VMware Storage vMotion with vSphere 5.0 or later
To avoid conflicts with Storage vMotion in vSphere 5.0 or later, NetBackup should conduct backups through the vCenter server, not through the ESX host. A backup directly through the ESX server may fail if Storage vMotion simultaneously migrates the virtual machine's files. In addition, the virtual machine's snapshot files may be stranded or other problems with the virtual machine may result. VMware has acknowledged this issue.
If the backup fails, the NetBackup job details contain a message similar to the following:
Error opening the snapshot disks using given transport mode: Status 23.
To back up a virtual machine while its files are in the process of migration, NetBackup must conduct the backup through the vCenter server.
