dlt gone away on adaptec 2940

[mark rowlands]

a previously functioning dlt has "gone away" He had moved over to a
windows box
I judged it to be more in need of regular backup ;-) When it moved back
to it's
rightfull home viz :-

FreeBSD pcmarpxy.mine.nu 4.9-STABLE FreeBSD 4.9-STABLE #0: Thu Jan 15

The DLT (an hp 20/40gb DLT IV) which is indeed on scsi id 5 has
definitely not
physically gone anywhere, lights flashy flashy and tapes load but
FreeBSD seems
no longer interested. Still works under Win2k (same cable) There are no
other
devices attached to the card.

 Any wise words ?
