Two dead disks in HSZ70 - but which raid/mirror/stripe did they b elong to?

Greetings,

I have here in front of me an AlphaServer 4100 with many disks connected via
dual-redundant HSZ70 configuration in a couple of StorageWorks shelves.

Loads of SCSI errors were logged overnight and upon investigation two disks
(DISK10100 and DISK60300 to the HSZ) seem to have died or at least gone out
of commission (present in 'FAILEDSET' and orange attention light flashing on
disks).

On doing a 'show failedsets' it shows the two disks in the failedset. I
have tried doing all the other permutations of 'show ...' I can think of to
try and work out which mirror/stripe the disks came from without any sucess.

Basically I want to know how to tell which mirror or stripe the disks came
from so I can assess to what lengths I should go to ensure my data is safe
and how urgently I need them back (i.e. I'd be more concerned if it's a
mirror our database resides on than if it was a stripeset we use as a
repository for large raw data files to load into the database).

How can I find this out from the HSZ70 console?

Any assistance appreciated greatly.

NB. I have already logged a call with Compaq support, just want to know for
myself what broke etc.
