I rearranged somewhat to be clearer.

The firmware believes that the disk at ID2 died.  There's nothing the
system can do about this, it's a hardware problem.

You didn't have a failover disk assigned

Arrggh.  The firmware no longer things that this disk is failed, so it
initiates a rebuild of the RAID5 into it.

Completely separately, the battery was being charge cycled, it's back
to normal again...

And now the rebuild completes.

Perfectly normal, except that the controller shouldn't have thought
you lost a disk when you didn't.

The problem I posted yesterday is separate from the above.  You see
SCSI command timeouts, followed by the aacraid driver printing a
message like "scsi bus hung?".  We believe this to be a firmware
problem, so it potentially affects all OSs, all versions, though we
only have failure reports on Linux.
