A 1000 disks not seen with lad utility

Hello, gurus,

I had an Ultra10 connected to an A1000 with three mirrored disks. We had
a serous power failure problem last night, and today I can't connect to
the A100 anymore.
A probe-scsi-all sees the seven channels attached to the three mirrored
disks, plus the hot spare, and that's all. lad says there are no RAID
devices. rm6 saw no disks. The internal disk leds light up, but not the
ones on the A1000 corresponding to the disks We changed the scsi card ,
the SCSI cable, the controlles on the A1000, tried putting the disks on
an entirely new A1000. Same effect. The last thing I can imagine is the
terminator, or a deeper problem with the motherboard.
The internal system disks on the Ultra10 are all right.

My collleague's with the people who sold us the bay and the Ultra10
right now with the material, trying to fix the problem with them. I'm
setting up another server with yesterday's backup if everything else
fails. I'm also searching for some clues as to how we could access the
disks on the A1000.

Has anyone had this kind of problems with an A1000 before? Were there
other tools that you used to acces the disks? And in case the disks are
all right, is there a way to revert to a normal filesystem and plug them
on another server, without using the A1000?

Thanks in advance,

Rami Aubourg
