Hey all-
I have 2 SCSI disks on one adaptec SCSI card on my 4.1 Release version BSD
box. I screwed up my install and accidentally put the MBR on the second
disk. I used the FreeBSD boot manager (booteasy-- ohh yeahh). My kernel is
on the first disk on the first slice and when the boot loader comes up it
defaults to 1:da(1,a)/kernel
When I specify 0:da(0,a)/kernel
I get it to boot up fine. Unfortunately this is going to be located
remotely and I need it to be able to boot correctly without intervention.
I have tried including
rootdev="disk0s1a"
in my /boot/loader.conf file and that doesn't seem to make any difference.
I have also tried:
"boot0cfg -B /dev/da0"
and a
"disklabel -B /dev/da0s1"
and it still doesn't work.
Any clue what I am doing wrong, and why it keeps defaulting to the 2nd disk?
I tried to include some stuff to help troubleshoot...
here is the relevant parts of dmesg:
