I have an ADIC scalar 24 autoloader with two drives. Drive 1 (/dev/st0) is currently being written to via a bacula job. Drive2 (/dev/st1) has a volume mounted in the drive but is not being used. Both were previously working.The problem is that Drive 2 won’t eject/unload the current volume.

Also, another oddity is that mtx is reporting that both drives contain ‘Unknown Storage Element Loaded’:

[root@monk bacula]# mtx -f /dev/sg3 status

  Storage Changer /dev/sg3:2 Drives, 23 Slots ( 1 Import/Export )

Data Transfer Element 0:Full (Unknown Storage Element Loaded):VolumeTag =                            

Data Transfer Element 1:Full (Unknown Storage Element Loaded):VolumeTag =       

….

When I try to unload the Drive 2 (accessed as Element 1 above) into slot 1, which is empty, I get the following error.

[root@monk bacula]# mtx -f /dev/sg3 unload 1 1

Unloading Data Transfer Element into Storage Element 1...mtx: Request Sense: Long Report=yes

MOVE MEDIUM from Element Address 257 to 4096 Failed

I have even attempted a physical eject of the drive, no dice. Wonder if this is hardware related or if I’m missing something.

Appreciate your help.

Thanks,
