The problem, as Andreas said, is that I had one of the SCSI targets set to
7, the same target as my SCSI controller. Shut down box, fix target, boot
-r and all is well with the world.

Thanks again to all who responded.

And the original question:

I'm trying to get some new Seagate disks installed in a Sun SS1000E with a
QLogic differential SCSI controller and a big differential SCSI tray. I do
a probe-scsi-all and it sees everything fine and dandy. When running dmesg
I get the following output:

@2,10000/sd@0,0 (sd36):

and so on up to (sd50).

Here's what I get when running format:

The first two disks exists and are fine (old Sun 510mb ones) and the last 3
exist and are fine (Sun 9.0gb ones). It's all the stuff in the middle!
There's only 4 disks and it seems to see 12 disks (i.e. disks 2-13)? This
confuses me...

There are 4 x Seagate disks in a big differential SCSI tray. The first two
are full-height drives, the second two are smaller ones but they all have
the same serial number/type as reported by doing probe-scsi-all from the
PROM.

The terminator is definitely a differential one and I've tried two different
ones with the same results, they were working a while ago with two of the
drives in there, I'm trying to add two new ones (the smaller ones, not
full-height).

As you can probably guess I'm fairly new to SCSI stuff and am not too sure
how these SCSI trays work. With the larger Seagate disks they have a
connector for power, SCSI and for a little cable to set the SCSI ID on the
front of the tray. The smaller drives don't have a connector for the SCSI
ID cable so I manually set them to different ID's than the other two.

>From what I can tell it all seems to be OK and the PROM thinks it's OK but
there's something wrong somewhere, damned if I know what.

Any help at all would be greatly appreciated.

Kind Regards,

Adrian Blount
