I have had this combination working for months with no problems, so
you must have either a configuration problem, or some other hardware
problem. First, there are some problems with SCSI IDs. I put
my HP disk on SCSI ID 1 and the Archive 2150S on ID 4. The archive
doesn't seem to get recognized on any ID < 4. Also you need the
latest ROMs (21247-5 I believe) in the 2150S.... The rev 3 would not
work properly. Also, check your cabling and terminators. One thing
I quickly found out is that SCSI is power terminated..... ie if I
switch off my tape drive, my disk gets scribbled onto! Anyway, this
combo of the 1542A and 2150 + a nice fast SCSI disk is
fantastic.... it is very fast, and I don't eat a slot and IRQ for a
seperate tape controller.
