Library Options - Compaq StorageWorks SSL2000 Series Reference Manual

Library Options

Configuration: Lets you configure the Library as a stand alone, master, or
slave unit. The default is stand alone.
NOTE: For multi-unit operation, you must first install a Pass-Through Mechanism. See
chapter 3 "Installing and Removing the Pass-Through Mechanism" for further
instructions.
Unload Mode: Lets you determine whether a SCSI MOVE MEDIUM
command is interpreted as Implicit or Explicit. If Implicit, the unit unloads a
drive before attempting to move a cartridge from that drive. If Explicit, the
host must issue a SCSI UNLOAD command to a drive before each MOVE
MEDIUM command that removes a cartridge from that drive. The default is
Implicit.
Numbering: Lets you specify whether SCSI elements in the unit display with
either zero or one. This affects only the front panel display, not the actual SCSI
element addresses. The default is 0.
Auto Clean: Lets you enable an automatic cleaning cycle which operates as
part of the cartridge unload sequence whenever the Use Cleaner LED lights.
To use this option, you must have reserved a slot for a cleaning cartridge using
the Reserve Slots option. The default is Disabled.
Library Mode: Lets you set the robotics operating mode to Random,
Sequential 1, Sequential 2 or Sequential Split. The default is Random.
NOTE: The sequential operating modes are available in stand alone configuration only. If
only one drive is installed, only the Sequential 1 option is available.
