I think, the first scsi device is sg0, the second is sg1 etc.
i have from id0 - id4 scsi drives, id5 is a cd-rom drive, id 7 is the
adaptec, id8 is the tape and id9 is the changer. So i think
id0 -> sg0
id1 -> sg1
id2 -> sg2
id3 -> sg3
id4 -> sg4
id5 -> sg5
id8 -> sg6
id9 -> sg7
is this correct?
Here the sg-devices from the system:

Sorry, a bug from me, device /dev/sg7 works fine. You can see the resutl from
"mtx -f /dev/sg7 status" and "mtx -f /dev/sg6 status"
I'm wondering for this:
root@fileserver:/ > mtx -f /dev/sg6 status
mtx: Request Sense: 70 00 02 00 00 00 00 16 00 00 00 00 04 00 00 00 00 00 00

I'm using chg-scsi from /usr/local/libexec/chg-scsi
Here is the Config from chg-scsi named chg-scsi.conf
*** Begin Config ***
