Starting with NetBackup software version 8.1 (NetBackup Appliance 3.1), PBX changed the location of the IPC file creation to the /var/VRTSpbx/root directory. On NetBackup appliances, the policy for the Symantec Data Center Security Agent (SDCSA) does not allow chown and chmod operations on this updated PBX path.
