I got a quice response from "Firmin, Julie" <Julie.Firmin@capita.co.uk>,
so thank you for that.

I just want to head this off -- we're currently working with Sun's storage
support group, and through failing/reviving drives and identifying some
faulty array ID settings, they're helping us through the problem, though
it looks like we're going to lose the data on one dead LUN.

Thanks again,
