h ithere,

had your same problem with a Sun Storedge L20 tape loader with 2 drives:
heres your solution:

run
contrib/config_sgen_solaris.sh

You'll be using the sgen(7D) generic SCSI device driver for the robot,
and end up with a device like /dev/scsi/changer/cXtYd0.

enjoy
liam

mt (Magnetic Tape) is supplied with solaris and manipulates the tape drive
itself

mtx (Magnetic Tape eXchanger :) is freeware and manipulates tape changers.

See freshmeat.net and/or sourceforge.net

Not, if as Gene mentioned, the system does not scan the appropriate id/lun.

As I noted, read the drive installation very carefully and

Your installation manual should provide similar directions.  The one Sun dlt
drive I installed for a client (not a changer) had very detailed directions
regarding changes needed to st.conf.  I was asked to look at it because the
technicians sent by the Sun Reseller could not figure out how to get it
working.
They were sure something was broken.  Of course they had been too smart to
Read The Fine Manual.  I had and was watching this comedy at a remote
terminal
with the st.conf changes already entered in my vi session.  When asked to
assist, I saved my changes and quit, touched /reconfigure and logged off.
Then I walked over to the console where they were working and started a
reboot.
I walked away before the reboot completed saying it "will work now".
