Looking at format it is missing 12 discs!
Which is probably not suprisingly the number of discs in the external storage
controller.
The other presnt disc have moved to c2 from c0.
The driver is the same for both the discs (it is the HP CQPAry3 driver) and the
external storage is on the same con
We haven't done 'zfs upgrade ...' any. I'll give that a try the next time the
system can be taken down.

No need to take the system down, it can be done on the fly.
The only downside to the upgrade is that you may not be able
to import the pool or file system on an ol

If zfs says that one disk is broken, how do I locate it? It says that disk
c0t3d0 is broken. Which disk is that? I must locate them during install?
In Thumper it is possible to issue a ZFS command, and the corresponding disk's
lamp will flash? Is there any "zlocate" command that will flash a par
Thanks for the information Richard!
The output of running arcstat.pl is included below. A potentially
interesting thing I see is that the "Prefetch miss percentage" is
100% during this test. I would have thought that a large sequential
read test would be an easy case for prefetch prediction.

First, I've been very impressed with ZFS performance and notification of
problems. It was because of this early notification that I should have been
able
to salvage an array properly!
Onto the problem I'm hoping you can solve ! :

Each ZFS block pointer contains up to three DVAs (data virtual addresses),
to implement 'ditto blocks' (multiple copies of the data, above and beyond
any replication provided by mirroring or RAID-Z). Semantically, ditto blocks
are a lot like mirrors, so we actually use the mirror code to read them
