Re: Paging volumes, size vs. number
More precisely, the sysprog can't *tell*, thus cannot worry about it in a meaningful way. I've been told that if the paging devices happen to be on the same rank in [some generation of] Shark, you won't be happy.

The hardest part, of course, will be turning the machine over to get the Microsoft license key off the bottom... On Tue, Jul 22, 2008 at 2:37 PM, Gary M.
