T013: Cannot read or invalid library serial number label

Description

Resolution
1. After being issued a move media from a host that
requires a GET from a drive, the drive never achieves
the unloaded state.
2. When GUI commands are issued that require a drive
unload (manual drive unload, move media, etc.) and
the drive never achieves the unloaded state.
Note: Since the library will always issue an unload
command, it will not be possible to determine if a host
unload command failed first, followed by a subsequent
failure of a library issued unload command.
Drive fails to unload after the library issues an unload
command.

Perform "DR003: Drive Unload Diagnostic" on page 10-31.
Before replacing a drive, refer to "Diagnosing a Problem"
on page 9-3 for additional diagnostic procedures.
The library will report a problem when it cannot read a
serial number or detects an invalid serial number.
1. At first boot up during installation, the library must
establish the serial number for the first time. There may
be no serial number in system memory at this point.
2. At any power up, system memory already has a serial
number established for the Library Control Blade.
3. A Library Control Blade is improperly swapped into a
different physical enclosure and the system reads the
physical enclosure label.
1. Library Control Blades swapped between libraries.
2. Label is damaged.
3. Bar code scanner not working properly.
4. Entire communication path to bar code scanner is not
working properly.
