Symptoms

Customer environment:

Library Type: SL3000 RoHS Level: 2006
Version: FRS_4.31 (7.33.00)

Backup application : DIVA version 6.5

Customer has encountered one issue with the robot which has been replaced. Afterwards a drive failed as the load mechanism seemed to be defective. Customer tested the drive load function using RecvrMove from SLC by following the steps from the below document:

How to Move tape from a cell via SLC (SL-Console) using RecvrMove to the CAP and re-enter the cartridge(s). (Doc ID 2093578.1)

Drive failed to be loaded with tape ARC503 but the tape was not returned to its original slot. Tape was ejected from the library and the drive was replaced.

After drive replacement, the backup application DIVA was explicitly requested to load the tape ARC503 to a drive as some important files might have been requested in the backup process for restore job. However, the fact that the tape have been ejected from the library heavily impacted in DIVA operations as DIVA ACTOR tried to mount the tape to each drive and downed all of them as it failed to find tape ARC503.

SL3000 Robot manager SCSI Logs reported that the mount request was sent at slot level, and the corresponding slot (where DIVA knows that the ARC503 tape is stored) is empty (because that tape has been used for a testing, then ejected from the cap, then reinserted, outside the DIVA system control (via SL console)

This suggests that Diva tried to move the tape from source slot 2068 (which was the last known location for the tape ARC503) and the library returned the SCSI Sense Code SenseKey=0x05, ACS=0x3b, ACSQ=0x0e, which corresponds to the message: 'source element empty'.
