This night we had some problems with an Areca ARC-1220 RAID controller
(arc driver) installed in an OpenBSD 4.4 amd64.
After the substitution of a couple of HDs the system restarted (in
rebuilding mode), but there was a problem: the RAID disk no longer boot!!!
The system see the controller, it correctly boot and seems to work ok.
The controller BIOS seems ok, apart from being in "Rebuild" state, but
this already occurred another couple of times before with no particular
problem.
But this time, after the controller starts up, when the PC BIOS should
boot from the disk, the following message is written to video and
nothing more happens:
Using drive 0, partition 3.
Loading...
Looking at the controller "System events" I found a message that I have
never seen before:
Rebuild LBA
It seems that the controller messed-up with something in the boot
sequence of OpenBSD, but I cannot find exactly what. I have done a lot
of attempts with the fidk, disklabel and instalboot, but with no
success. I'm worried to experiment too much with that commands, because
I'm really scared to destroy all the data in the disk.
Anybody can tell me what is the exact problem, and maybe suggest the
correct commands to restore the situation?
Thanks.
