When Unload Assist is enabled, the library will unload tape drives when
a move command from the tape drive is received. When Unload Assist is
disabled, the tape drive must be unloaded prior to a move command, or
the move command will fail. This setting is enabled by default.
Operator Panel

5 Save the library configuration (see
on page 101).
The library uses the actual tape drive serial numbers by default (logical
SN addressing is disabled). Enabling logical SN addressing 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. This setting 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 each tape drive from
the library in order for the change to take effect.
