I have an older Supermicro system (370DER) with a built in two-channel scsi controller. It'll happily boot from whatever scsi device I give it. I have a pair of disks on channel-A, mirrored using gmirror (da0s1 and da1s1 are the providers) and it'll happily boot from either. Not quite as nice as automaticall falling-over, but close enough for my particular use. g.Received on Mon Sep 27 2004 - 20:18:30 UTC
