Tape Drive Logical SN
Addressing 3
The library assigns a fixed logical serial number to each tape drive slot in
the library (whether it is occupied or not). When the
Logical SN
Addressing
setting is enabled, the library reports only the logical serial
number to the host instead of the tape drive’s physical serial number. If
the tape drive is later replaced by another tape drive in the same slot, the
logical serial number remains the same. From the host application’s
perspective, the replacement tape drive is the same as the original.
Logical SN Addressing is enabled by default.
When the Logical SN Addressing setting is disabled, the library reports
only the tape drive physical serial number to the host.
The library System Information Report shows both the logical and
physical serial numbers on installed tape drives for your convenience
(
Reports > System Information).
The path to open the appropriate screen is as follows:
• From the operator panel, select
Setup > System Settings.
Caution: If you change the logical serial number addressing
setting, you must power cycle the library in order
for the change to take effect.
Caution: Use caution with this feature, as it can be accessed
by both Admin and Service login users. Enabling
this feature in an existing installation will change
the presentation of the tape drive serial numbers
to the host computer and host applications. Some
host operating systems, and some application
software, will no longer see a tape drive if the
serial number changes (by use of this feature)
from a previously set host configuration. If this
happens, you will need to reconfigure the tape
drives in your backup application.
