Sun Cluster HA for NetBackup (Sun Cluster 3.1 Data Service 5/03 Release Notes)

Sun Cluster 3.1 Data Service 5/03 Release Notes

If the VERITAS NetBackup client is a cluster, only one logical host can be configured as the client because there is only one bp.conf file.
If the NetBackup client is a cluster and if one of the logical hosts on the cluster is configured as the NetBackup client, NetBackup cannot back up the physical hosts.
On the cluster running the master server, the master server is the only logical host that can be backed up.
Backup media cannot be attached to the master server, so one or more media servers are required.
