some library functions, knowing which labels are bad enables you to
replace them with good ones as soon as possible.
When you enable Unlabeled Media Detection, the calibration sensor re-
scans slots identified as empty in the inventory to see if a cartridge is
physically in the slot. If so, the library reports the cartridge as having an
unreadable barcode.
This feature is disabled by default. When enabled, the following occurs:
• The re-scan may take up to several minutes to complete.
• You can configure the library to re-scan only the I/E station slots that
were identified as empty, or all the slots in the library that were
identified as empty.
• The library configuration report indicates media with unreadable
barcodes by displaying a red triangle in the corner of the slot.
• The library user interface lists
No_Label
as the barcode for all
cartridges with unreadable labels.
• The library posts a RAS ticket (T143) when an unreadable barcode
label is detected. As long as that ticket remains open, no more T143
tickets will be issued, even if more unreadable barcode labels are
found.
• An unreadable barcode label is re-scanned every time the cartridge
moves to a new location to check if it is readable in the new location.
The paths to open the appropriate screens are as follows:
• From the operator panel, select
Tools > System Settings
.
• From the Web client, select
Setup > System Settings
.
Note:
The library always re-scans “empty” slots in the top and
bottom rows of the library, even if you don’t enable the
Unlabeled Media Detection feature. This is because
occasionally a small or poorly placed label cannot be read
by the barcode scanner in those two rows. The calibration
sensor re-scans the bottom row, and the picker physically
checks the top row because the calibration sensor cannot
reach it.
“Bottom row” here means the bottommost available row
as indicated in the library configuration report.
