About assigning tape drives to different hosts
The robotic tape drives can be divided up among NDMP hosts and NetBackup servers.
The following figure shows the NDMP and non-NDMP storage units with the following configuration:
Tape drives 1, 3, and 5 are attached to NDMP hosts. They are in the NDMP storage units that can be used for NDMP backups (local or three-way).
The commands that control these drives originate on the NetBackup for NDMP server and are sent through the NDMP connection on the network. The NDMP server application on each NDMP host translates the NDMP commands into SCSI commands for the local drives.
Tape drives 2 and 4 are attached to a NetBackup server. They are in non-NDMP storage units and are controlled in the same way as other drives on NetBackup servers. Depending on the type of storage unit, these drives can be used for the following:
Non-NDMP clients of NetBackup
In the case of tape drives in Media Manager storage units, they can be used for both NDMP (local or three-way) and non-NDMP backups.
In the following figure, all of the tape drives are used for NDMP backup except drive 4.
