Explanation:

This issue occurs if any one of your backup hosts in the backup host pool is at a lower version than 10.1.1, and the protected NAS volumes reside on Dell EMC Unity, Dell EMC PowerStore, or Hitachi NAS storage array.

Workaround:

Remove the backup hosts from the backup host pool that have a lower NetBackup version than 10.1.1. Alternatively, for these policies, use a different backup host pool that has only NetBackup 10.1.1 hosts.
