4. Set Element Base: This setting lets you set the base addresses of each
of the four SCSI elements of the module. In order to identify sources
and destinations in commands to the robotics, the MiniLibrary System is
divided into elements, each of which is assigned a separate designator or
element address. The transport element is the robotics mechanism itself;
the storage elements are the slots in the magazines; the transfer elements
are the drives, and the import/export element is the mail slot or slots.
The module reports these settings in response to the SCSI MODE
SENSE command, in the Element Address Assignment Page. The
defaults are transport element base = 0000, storage element base = 0001,
transfer element base = 00F0, and import/export element base = 00E0.
5. Set Identification: This setting lets you:
a. Specify the response of the module’s robotics to the SCSI
INQUIRY command in the Vendor ID and the Product ID fields.
The defaults are: Vendor ID = DEC; Product ID TL89x.
b. Set Date: Lets you set the MiniLibrary system calendar.
c. Set Time: Lets you set the MiniLibrary system clock.
6. Set Baud Rate: Lets you set the data transmission rate of the Expansion
Unit’s trace port. This function is intended for Customer Engineers
(CEs) only. The default is 38400 bits/sec.
7. Set Serial number: This setting lets you alter the Expansion Unit’s
serial number as stored in the unit. The module’s robotics reports these
settings in response to the SCSI INQUIRY command, in the Unit Serial
Number Page.
8. Set Unload Mode: This setting determines whether a SCSI MOVE
MEDIUM command is interpreted as implicit or explicit. If implicit, the
Expansion Unit unloads a drive before attempting to move a cartridge
from that drive. If explicit, the host must issue a SCSI UNLOAD
command to the drive before each MOVE MEDIUM command from
drive to a slot. The default is Implicit.
9. Set Auto Clean Mode: This function, when enabled, senses the tape
drive’s cleaning request and after the next unload, load a cleaning
cartridge into the drive. After cleaning completes, the cartridge is
returned to slot. The default is Disabled.
NOTE:
This function is application-dependent.
