Thanks - the problem must be the Promise controller. I'll have to dig
up something else.

Can grub deal with that for the /boot partition? A default install on a
scsi drive that came in after the sata's wouldn't boot if I removed one
of the sata disks.
What I want to end up with is the system on a pair of raid 1 scsi
drives, then a 3-member raid1 mounted separately where one is
periodically swapped out and taken offsite. I'm currently doing
something similar with 2 IDE and one firewire drive but the firewire
driver doesn't seem reliable enough to leave the drive connected much
longer than it takes to sync.
