E250/DDS-3 SCSI tape drive not recognised

All,

I've got an external Digital SCSI SE tape drive, which I wanted to connect to
the external SCSI port of a Sun Enterprise 250. As soon as I do that, the
tape drive locks up (all lights except for the on/off indicator light go
off, the tape won't eject). When I disconnect the SCSI cable and
terminator, the statuslight on the drive comes back on and the tape ejects
as normal.

The server does not see the tape drive when the cable and terminator are
connected, not even at the ok prompt with "probe-scsi". The tape drive
and the scsi port on the server both have the same SCSI diamond symbol (a
single diamond with a dash in the righthand corner).

This tapedrive works perfectly on a Dell workstation with an internal SCSI
card.

I would be grateful for any suggestions.

Cheers,
Tony

What SCSI ID are you using? What about the cable?

I tried ID 1 and ID 4. The cable is brand-new Centronics (tape end) to
wide-scsi (server end)

An ID of 4 or 5 should be OK. Check that there's no conflict with
the ID. The cable might be suspect. See if you have another one
that you can try.

Gee do I feel stupid! :-( How could I possibly trust that a new cable
straight out of the wrapper would work? It was the cable all right.
Thanks...
