Ok I've just done this with the mtx 1.3.11 utility:
# /usr/local/sbin/mtx -f /dev/scsi/changer/c1t0d0 inquiry
Product Type: Medium Changer
Vendor ID: 'HP '
Product ID: 'C7145-8000 '
Revision: '206S'
Attached Changer API: No
So that proves mtx 1.3.11 on it's own can communicate with the robotics
controller in the L9. This points to a problem between chg-zd-mtx and mtx
itself.
I will also look at the devices for the tape drive itself as there is a
/dev/scsi/sequential link but the 'st' driver did bind to the tape drive
as 'st8' when SunOS 5.9 booted last time. Can /dev/rst8 or /dev/nrst8 be
used to reference the tape drive or does it need to be one of the
/dev/rmt/xxx links (to give some specific functionality to Amanda)?
Out of interest, could the /dev/scsi/sequential device handle be used as
the device for the tape drive? Amanda's components might require things
that the sgen driver doesn't provide when it comes to direct communication
with a tape drive.
