Sun 8mm 8705DX Tape Drive 1

[drmyers208]

Help!
I can't get my get my Sun 8705DX tape drive to work. I inherited a Sun Ultra 10 machine complete with an external 8705DX tape drive and Yamaha 4x4x16 CDROM burner (both SCSI). I have Solaris 5.8 installed and working fine. My problem is I can't figure out how to communicate with the external tape drive. I installed several different 8mm tapes (green light is on) without success. I have the SCSI id set as '4' which doesn't interfere with anything. I try using the commands:
mt -f /dev/rmt/0 status
and
mt -f /dev/rst/0 status
for options 0-7 without any drives being detected. What am I missing here? Is there a missing driver perhaps?

have you done a boot -r from ok
or reboot -- -r

Try this command "devfsadm -v -c tape"

You can use this command to check your scsi device :
# cfgadm -al

Good luck

Thanks for all that replied to my question. It turns out the problem was some type of hardware conflict with my external CR-R drive that was daisy chained to the tape drive. Once I unplugged this drive the tape drive worked as advertised!
