I'm running into what looks like the same problem with an ecrix vxa lvd
external setup. I was using an ncr8xxx with only external connector and
got parity errors with the terminator on (terminator light indicated the
expected single-ended connection). W/o the terminator the drive didn't
show at all.
Hooked it up via an advansys asb3940u2w today. Nothing when hooked on the
external connector regardless of the terminator. The terminator indicated
lvd with nothing else on the chain or single-ended when I hooked up a
single-ended hard drive to the internal connector. The hard drive was
usable, but still no traces (with the advansys bios interface, during boot
or via proc) of the tape drive.
My cable came out of a box that was used to send on-board scsi to the
outside of the box, so I took the external cable off the external
connector on the pci card and hooked it up to the end of the internal
cable, e.g. the tape drive is still in the external enclosure connected to
the external cable, but the external cable is now hooked to the end of the
internal cable through the open case.
With this configuration the tape drive works with or without the hard
drive on the chain when the terminator is on the tape drive, which
is at the end of the chain. With the hard drive it is single-ended, w/o it
is lvd. If I disconnect the hard drive and the terminator the tape drive
works just fine hung off the internal chain.
Seems to me that the external interface on the card isn't getting turned
up. Is that a simple configuration something or another that I'm missing?
I've used external devices, mostly hard drives and cdroms, without
problems in the past. Never had to do anything special for them. I have
had tons of problems getting tape drives to work, but always accounted
that to the fact that the only tape drives I got to use at work were the
ones I salvaged out of the scrap pile ;-). The DLT7000 I got to test for a
few days worked like a charm, better than under AIX, in fact.
A friend bought an ecrix vxa single-ended unit at the same time and has
had no probs whatsoever with his. I think his is internal, but probably
have to wait for him to get up in the morning to find out :).

All the posts I've seen the last couple of days were tape drives. Is this
something in the tape system? I don't have any other external devices
right now, but am trying to borrow a hard drive shoebox to test with...
