Hi,

I recently bought a 2nd hand DDS3 in a unipack 611 case, with the
intention of installing it in the spare 5.25" bay below the DVD in my
SB1K. Installation was ok from the perspective of power and 50 pin SCSI
cabling however on the OBP I am getting persistent SCSI bus errors,
presumably because the device is not set to its accustomed device '5' on
the bus. The drive has (what appears to me) quite an unusual pin SCSI
selection cable that was connected to the external SCSI selector in the
unipack case (3 pins on top, one on the bottom). Having looked at
sunsolve and the archives of this group I haven't found anything
relevant. I would appreciate any pointers members of the group might be
able to impart.

Thanks and regards,
Andrew

I don't have a Blade 1000, but have fitted a DDS4 tape drive in a Ultra
80, which from the outside at least looks similar to the Blade 1000. But
I've never looked inside a Blade 1000, and I am aware they are not too
similar.

Most DDS4 tape drives use 68-pin connectors. I'm told some HP ones will
work on a narrow bus, but I bought a Sony DDS-4. Someone then said that
whilst he got HP drives working on narrow, he was not able to on a Sony.
I gave up and added a wide SCSI card inside mine, since there is no easy
way of adding a wide device.

I really don't believe the SCSI ID is critical. My internal DDS-4 is on
SCSI ID=1, the DLT-8000 on SCSI ID=1 too (HVD, so different controller)
and I have an external DDS-4, (which I will remove soon) on SCSI ID=6.
So I have tapes on SCSI ID 1 and 6 with no hassle.

# ls -l /dev/rmt/[0-2]
lrwxrwxrwx 1 root root 42 Jan 14 23:28 /dev/rmt/0 ->
.../../devices/pci@1f,4000/scsi@3,1/st@6,0:
lrwxrwxrwx 1 root root 40 Feb 21 22:47 /dev/rmt/1 ->
.../../devices/pci@1f,4000/scsi@2/st@1,0:
lrwxrwxrwx 1 root root 42 Feb 7 17:03 /dev/rmt/2 ->
.../../devices/pci@1f,4000/scsi@5,1/st@1,0:

If the drive came from a 611 box, I'd try it back in that on the
external connector. I assume you did not buy it new, since DDS-3 is a
bit old now. So it could be faulty.

Also check termination carefully. I assume if it came from a 611 box it
is not terminated.

There's a 2000 in this office with an exabyte unit installed in it.
Works just fine.

Proper termination needs to be checked.

SCSI ID doesn't matter as long as it doesn't conflict with other
devices (so avoid 7 [HBA] and 6 [DVD/CD, if installed)

It's it;s owt like mine in my newly aquired SB1k then it's jumpered
across the pins for SCSI ID 0 and SCSI ID 2 from which it identifies
itself as SCSI ID 5!

Mines an HP one as I think most are.

Is that via the DIP switches?

I understand that you can allocate any ID and 5 isn't special per se,
however it occurred to me that without any jumpers the DDS3 would
default to SCSI 0 on the bus - in conflict with the primary FC-AL drive.
