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 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 RAS tickets will be posted if
there are motion-related problems, scanner communication problems, etc.
Detection Scenarios • At first bootup from clear to ship, the library must establish the serial number
for the first time. There may be no serial number in system memory at this
point.
• During any bootup, the library must be able to read both the serial number
and the WWN. If neither of these barcodes is readable, the library cannot be
certain that the serial number stored in memory is accurate.
Root Causes • Label is damaged.
• Label is missing.
• Label is physically obstructed.
• Label is readable but does not meet minimum criteria to be considered a
library serial number label.
• Scanner cannot read serial number label.
• Damaged module terminator or module-to-module cable with bent or broken
pins.
