Thanks - this is just the first time I'd seen where it didn't at
least install on the first drive automatically. I had to run grub
by hand from a rescue cd boot to fix it. Also, most of the
instructions I found about installing on the 2nd drive were for
IDE controllers and a bit different. Your approach gets it right for
SCSI where a failure on the 1st drive makes the device names shift
up. At least it works in a simulated failure where the 1st drive
is removed. Does anyone know if there is a common failure mode where
the 1st SCSI drive is still detected at boot as /dev/sda but doesn't
work?
