medium changer

[asteti]

Hi,

is there anything I need to configure for using tape library? Currently, I can see tape drives but not medium changer:

lsscsi -g
[0:0:0:0] disk HP LOGICAL VOLUME 6.64 /dev/sda /dev/sg1
[0:3:0:0] storage HP P410i 6.64 - /dev/sg0
[1:0:0:0] storage QUANTUM Scalar i500 5951 - /dev/sg2
[1:0:0:1] tape HP Ultrium 4-SCSI H46Z /dev/st0 /dev/sg3
[1:0:0:2] tape HP Ultrium 4-SCSI H46Z /dev/st1 /dev/sg4
[1:0:0:3] tape HP Ultrium 4-SCSI H46Z /dev/st2 /dev/sg5
[1:0:0:4] tape HP Ultrium 4-SCSI H46Z /dev/st3 /dev/sg6
[2:0:0:0] storage QUANTUM Scalar i500 5951 - /dev/sg7
[2:0:0:1] tape HP Ultrium 4-SCSI H46Z /dev/st4 /dev/sg8
[2:0:0:2] tape HP Ultrium 4-SCSI H46Z /dev/st5 /dev/sg9
[2:0:0:3] tape HP Ultrium 4-SCSI H46Z /dev/st6 /dev/sg10
[2:0:0:4] tape HP Ultrium 4-SCSI H46Z /dev/st7 /dev/sg11

From what I understood, /dev/sg2 and /dev/sg7 are mediumx but why it is showing as storage?

mtx status command fails:

also, /proc/scsi/scsi shows quantum as raid instead of medium:

cat /proc/scsi/scsi

This is a Quantum library but with HPE OEM drives. The Firmware H46Z is not an HPE Firmware revision. I suggest that you talk to Quantum about this issue. But from what I am seeing it could be an issue with the controller on the library
