Basic Disk Disk Staging Storage Unit (DSSU) configured in NetBackup 7.0 Cluster master/media server fails to trigger High Water Mark (HWM) cleanup automatically

Issue



NetBackup 7.0 does not supported clustered media servers, unless they have been upgraded from NetBackup 6.5.x.   However, a clustered master/media server is permitted even when installing NetBackup 7.x and not upgrading to NetBackup 7.x.

Unfortunately, Basic Disk Disk Staging Storage Units which use the cluster/virtual NetBackup name for the storage unit and storage server name, will not perform the HWM trigger and cleanup any staged backups images when exceeding the HWM.  This is a very similar problem experienced for Advanced Disks.
