Resolution
To test your hardware using tar, mt and mtx commands you will need to know what devices your hardware is attached to. To find this information out first use this command to see what devices are attached to your computer and their hardware addresses.
cat /proc/scsi/scsi
Attached devices:
Host: scsi2 Channel: 00 Id: 00 Lun: 00 Uid: 00
Vendor: EXABYTE Model: Exabyte 221L Rev: 3.3
Type: Medium Changer ANSI SCSI revision: 02
Host: scsi2 Channel: 00 Id: 01 Lun: 00 Uid: 00
Vendor: IBM Model: ULTRIUM-TD1 Rev: 4561
Type: Sequential-Access ANSI SCSI revision: 03
Then type this command
dmesg | grep s[g,t][0-9]
2:0:0:0: Attached scsi generic sg32 type 8
2:0:1:0: Attached scsi generic sg33 type 1
st 2:0:1:0: Attached scsi tape st0<4>st0: try direct i/o: yes (alignment 512 B)
You can then match :0:0:0 to Host: scsi2 Channel: 00 Id: 00 Lun: 00 to see that the autoloader is attached to /dev/sg0.
2:0:1:0 matches Host: scsi2 Channel: 00 Id: 01 Lun: 00 so the tape drive is attached to /dev/sg1 and /dev/st0 -
