• The SHOW command helps to verify that all required attributes
have been set. It identifies missing but required attributes with
an asterisk (*).
• The ADD command names the device and adds it to the
configuration file.
6.4.3.1 Considerations
• Always use 5190 as the product number when configuring the
T16/5155/5159 DLTtape Drive FRU.
• Unit numbers are determined by the controller and must match
the SCSI ID of the drive.
• Because an MFC can control only one tape drive, the only valid
unit number for a drive attached to an MFC is 5.
• The 3216 controller can control one or two tape drives. If the
controller manages only one drive, use the default unit number
(5). If the controller manages two drives, use unit numbers 4
and 5.
• Compression as a device attribute can be specified through
COUP for the T16/5155/5159 DLTtape Drive FRU (Note:
use “5190” when specifying peripheral in CONFTEXT File).
Use COUP to enable or disable compression with
these attributes:
