DVD Drive/Tape Drive Unit Administration

DVD drive/tape drive unit configuration is used to specify a DVD drive unit and
tape drive unit by specifying a PCI card port that can connect to the DVD/tape
drive.
Note – A DVD drive unit and tape drive unit needs to be specified only for

DVD drive unit. In an M5000 server, the MBU#0 on a MBU_B has the DVD drive
