Why don't you try

ioscan -fnC tape

disk won't show you a thing.

newops4:/#:ioscan -fnC tape

Hi,
You should try:
> ioscan -funC tape
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tape 0 0/0/2/1.0.0 stape CLAIMED DEVICE HP C1537A

/dev/rmt/c3t0d0BEST /dev/rmt/c3t0d0DDSn
/dev/rmt/c3t0d0BESTb /dev/rmt/c3t0d0DDSnb

ALl the best

Ok ..
# ioscan -fnC tape
Class I H/W Path Driver S/W State H/W Type Description

Hi Richard:

Now that you properly used ioscan it appears that your tape drive is ready - assuming you have a tape inserted in the drive. Note that you have both a long name e.g. c0t0doBEST and simply a 0m. Both of these are equivalent and typically you use the 'short' name. The suffixs:
0m - Rewind on close
0mn - Norewind on close; you can append several sessions to the tape
0mb - Rewind 'Berkeley' style
Omnb - No rewind, 'Berkeley' style

I suggest that you use the 0mnb if you are doing any sort of multiple sessions to the same tape.

Hi Richard,

Test 1 - put a tape in the drive and do mt -t /dev/rmt0m rewind

Test 2 - write something on the tape, say a tar file
tar cf /dev/rmt/0m somefile_or_dir

Test 3 - Try it with make_tape_recovery
/opt/ignite/bin/make_tape_recovery -a $/dev/rmt/0mn -I -v -x inc_entire=vg00

Good luck,
Darrell

Yes and you have a DDS3 (125m 4mm DAT)...

All the best

Sorry Richard, I made a slight mistake in my post ($ in front of tape device path). It should be:
/opt/ignite/bin/make_tape_recovery -a /dev/rmt/0mn -I -v -x inc_entire=vg00
