The disks are setup with Disksuite, but the disk which I think the
errors are referring to (c2t2d0) is not part of any disksuite set. I am
just running a format / analyse on the disk at the moment to see if it
brings anything up. Looking at the iostat output does show that
Controller 2 has "2" hard errors for each disk. Maybe the Controller
itself is at fault.
Thanks in advance - Julian.
