T013: Invalid Library SN Label, Library Cannot Initialize
Description GUI Description: A library module serial number label cannot be read,
preventing the library from proper initialization and operation.
Explanation: The library logic learns the serial number of the system by
reading an internal serial number label. This is done at first bootup from a
“cleared to ship” condition in order to establish the serial number. It is also
done on subsequent bootups to confirm that the LCB Compact Flash
memory card is in the proper library. The library will report a problem when
it cannot read a serial number or detects an invalid serial number or another
barcode on the module label when in this "cleared to ship" condition. When
T013 is posted, the library cannot operate normally. Different tickets will be
posted if there are motion-related problems, scanner communication
problems, etc.
Detection Scenarios
1. At first power ON 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
library and the system reads the physical library label.
Root Causes
1. Library Control Blades swapped between libraries.
2. Label is damaged, misaligned, or placed on the cartridge incorrectly.
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

Note: The system serial number label is part of the enclosure FRU.

T014: I/O Station Magazine Missing
Description GUI Description: A library I/O station has been closed with a magazine
missing.
Explanation: There is a fixed bar code label location on the I/O Station
structure behind the removable magazines. It decodes as %XXX. The purpose
of the label is to allow the library to detect that an I/O Station magazine is
not installed. This is important on I/O Station magazines, because they are
user removable. While performing an inventory of the I/O Station
magazines, the library ends up verifying the presence of the magazine by
NOT detecting this special fixed label.
Detection Scenarios Any time the library attempts to inventory an I/O Station magazine, it will
read the fixed label if a magazine is missing. I/O Station magazines are
always expected to be present.
