Fellow AIX'ers:

We've been tracking down a SCSI problem and I thought I would post to
see if anyone has overcome this problem already.

One of our machines is a B50 and we have externally attached an
Exabyte E820 8mm tape drive (7208-222 equiv). We have now added an
Exabyte VXA-1 tape drive to the SCSI chain. The problem we are
having is the proper cabling and terminating of this configuration.

Research shows that when we try to MIX these drives (SE & LVD) that
for the LVD drive we need "high-byte-termination" . We have found a
cable that will accomplish this for us as www.scsicablesource.com but
we want to be sure that's what we need before purchasing it.

Here's a test that we performed: When we connect the VXA-1 drive
directly to the B50 and plug in an active terminator, the led on the
terminator stays dark indicating no termination power present. If we
take the cable out of the B50 and plug it into a Linux box with an
Adaptec SCSI adapter, the terminator glows like it should.

So, is there something different with the B50's connection that we are
overlooking?

Anyone familiar with or who might have experienced this problem
before, PLEASE provide some insight?

Thanks

Bob
