Solution 2325309.1 : SL150 - Random Barcodes Are Blank In The Web GUI

Applies to:

StorageTek SL150 Modular Tape Library - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.
SL150
GUI
BUI

Symptoms

Tapes that are shown as unreadable . In parallel we have also observed a few failures of our backups caused by a problem to read the barcode.

Random (?) tapes not showing barcodes in GUI...

Invalid tape labels in WebGUI

Customer also has oddly aligned external tape labels ...

Tapes with non-standard labels

Note: The above tapes do not conform to the Barcode Technical Brief having characters on the hub side of the label and the L6 media type designation to the right.

The SL150, running 3.00 firmware, did not complain of misreading the tapes. In fact, most of the time it reads the tape labels correctly with just a few tape labels showing blank in the GUI. The blank tapes changed position upon each reboot.

Changes

None reported

Cause

No obvious robot failure messages were seen in the Service Bundle but replacement of the robot fixed the issue. Customer advised to change their labels to conform to the Barcode Technical Brief (see doc ID 1364371.1)

Solution

Robot was replaced.
