lspci shows the following (Yes, I've installed Debian in the interim)

00:04.0 RAID bus controller: Compaq Computer Corporation Smart Array
5i/532 (rev 01)

This is all a bit frustrating because I have several Linux based Proliant
servers with the CISS hardware and they behave properly when the disk is
removed and re-inserted.  We also have LOTS of Windows based servers that
behave properly given the same test.  Makes me suspect some sort of driver
issue.
