•
Unload Assist
— Allows you to specify whether the library should
automatically eject cartridges from tape drives. When the setting is
enabled, the library will assist with tape drive unload operations in
the event that a tape drive is not unloaded by a host command. When
the setting is disabled, the library will not assist with tape drive
unload operations and reject a move request from a tape drive, if the
cartridge is not already unloaded. The
Unload Assist
setting is
enabled by default.
•
Logical SN addressing
— The library uses the actual tape drive serial
numbers by default. Selecting the
Logical SN addressing
check box
enables the library to assign logical serial numbers to all tape drives
in the library. Specifically, the library assigns a logical serial number
to a tape drive in a specific location, not the serial number of the
particular tape drive. If the tape drive is then replaced by another
tape drive in the same library location, the logical serial number
remains the same. From the host application’s perspective, the
replacement tape drive is the same as the original.
•
Manual Cartridge Assignment
— Administrative users can disable or
enable manual cartridge assignment. When manual cartridge
assignment is enabled (the default setting), the
Assign IE
screen
automatically appears on the operator panel once cartridges are
placed into the I/E station. The
Assign IE
screen prompts the user to
use the operator panel to assign the cartridges to a specific partition
or to the system partition. The cartridges can then be used only by the
assigned partition.
For more information on manual cartridge assignment, see
Disabling/Enabling Manual Cartridge Assignment
on page 70.
•
Disable Remote Service User
— For security purposes, prevents a
service user from logging in to the library remotely, from either the
web client or over the Ethernet service port. The service user will still
be able to log in to the library from the operator panel interface. This
option is disabled by default.
Caution:
If you change the logical serial number addressing
setting, you must power cycle the library (perform
a shutdown and press the power button) or
remove power from each tape drive for the
change to take effect.
