Error message "Move media from DRIVE to SLOT # failed" during library inventory (79788)

Date: Aug 2007
Affected NV Version: All
OS Version: All
Plugin version: N/A

Symptom: When NetVault tries to move media, the drive or drives in use are marked as offline.

The log will show:
Error 2007/08/30 11:03:52 318 Media 1-0.0.0 Move media 'XXXX' from 'DRIVE to 'SLOT 2' failed

Followed by;
Error 2007/08/30 11:15:01 0 Media 1-0.0.0 DRIVE 9: has gone down

Log Context of the move media error;
CAM 4 0 180352 Sense Key: '5', Ext Sense: '3b', Qual: 'd'
CHGSCSI 24 0 180352 CMD STATUS 'CHECK CONDITION' [2]

CHGSCSI 74 0 180352 CMD SENSE INFO 'DESTINATION ELEMENT FULL'
CHGSCSI 39 0 180352 Command at bit 7 of byte 6 is in error

The logs indicate that a command was sent to the drive to unload.

The log context message 'CMD SENSE INFO 'DESTINATION ELEMENT FULL' confirms that when the library tried to load the media, it found that the destination slot/drive was already occupied.

To resolve the issue, verify that the library is not completely filled up with Media, for example by having all slots full AND a tape loaded in all of its drives.

A good rule to follow is that when the slots are completely filled with media, the drives should always be completely empty.

This is a hardware related issue.
