Detection Scenarios
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.
Root Causes Drive fails to unload after the library issues an unload
command.
Possible CRU Replacements

Resolution 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.
T013: Cannot read or invalid library serial number label
Description The library will report a problem when it cannot read a
serial number or detects an invalid serial number.
Detection Scenarios
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.
Root Causes
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.
Possible CRU Replacements Library Control Blade
Possible FRU Replacements
v Picker Assembly
v Y Motor
v Y-axis Assembly
v Cable Spool
v Enclosure
Note:
The system serial number label is part of the
enclosure FRU.
Resolution Perform “DR007: Bar Code Scanner Diagnostic (a Library
Verify Test)” on page 10-32.
Before replacing a library component, refer to “Diagnosing
a Problem” on page 9-3 for additional diagnostic
procedures.
