Connecting a Storage Works 310 to an external disk.

Hi everyone,

I'm having some trouble with a Digital Storage Works RAID 310 model.

I'm hoping it's something I can fix via configuring the Digital Raid box,
and not a Solaris side problem (Hence mailing this list).

Basically , the system won't boot once the Storage Works array plugs in. My
SCSI knowledge is pretty low, so I think the problem may be conflicting SCSI
ID numbers, or something of the type.

The problem: (It's a few lines, but I don't want to miss anything
out)......


We have a Storage Works 310 Array, 5 disks, all single (JBOD) disks.
(Plus a hidden 6th disk you see when you take the cover off)

It was plugged into another Sun box, working fine.
ie The disks are on the Storage Works, all formatted, with (Solaris) data,
working fine.

We took it away to use on a Sun Netra i, with one existing external disk.
Daisy chaned the Storage Works into the external Sun drive.
Powered on.
Sun box won't boot:
    Boot Device: /iommu/sbus/espdma_at_4,8400000/esp_at_4,8800000/sd_at_3:0

    Can't open boot device.

Hmmm. Looks like the Storage Works is confusing the box.

There's 2 lights on the Sun external drive "HIGH" and "LOW"...
  Sun Drive on it's own (working) - Both lights ON
  Sun Drive chained in front of Storage Works - Both lights ON

SCSI ID on Sun drive - "0"

So I opened Storage works box - ID was "0" , so I tried flicking it to "1"

Reboot....
 Both "HIGH" and "LOW" lights on Sun box are ON ,
 but...
   Sun Box: Still won't boot (Same error)
   Digital Array: Once continuing (ear piercing) BEEEEEEEP


I know that we need to install the Storage Works software for Solaris (which
we have) but the first step I wanted to get going was to at least be able to
boot with all devices attached.

Unfortunatly, the Sun Netra i has only one SCSI port, so I can't put the
Storage WOrks on it's own port.

I was guessing that changing the SCSI switch on the Storage WOrks would fix
things, but the Storage works isn't obviously happy with this (As my
bleeding ear drums can testify)
PS - The Sun disk appears to be auto terminating  (Didn't have a terminator
on the "Out" SCSI port and still booted fine.
Sorry if this ends up a Solaris problem, but I'm hoping by configuring the
Storage Works, it will work.  It DID work on the other Sun box (A different
model, with , from memory, a separate SCSI port )
Has anyone got any ideas?  I'm at a loss.
Thanks in advance,
Dirk.
