I have a machine here with many disks attached to it via several
controllers, as follows:
Onboard ICH9:
0 Empty
1 Toshiba 80GB rpool disk
2 8GB CF->sata, unused
3 ACARD 9010B, unused so far
Supermicro AOC-SAT2-MV8 #1
4 & 5 Samsung F1 750GB, "data"
Supermicro AOC-SAT2-MV8 #2
0-5 Hitachi 1TB, "newdata"
6 & 7 Samsung F1 750GB, "data"
When the system boots, it starts Grub quickly.  I pick the default
entry, then the text on the background goes away and it sits at the
grub menu for approximately 15 minutes before anything changes.  Then
it brings up the Opensolaris splash screen (blue with an orange
spinner bar in the middle) and makes a few disk accesses.  The spinner
goes for a long time, but the system doesn't start within 8 hours, and
all the disks are apparently quiet from the beginning until right near
the end.

After entering the things in the grub configuration one at a time, I
find the following data:
"findroot (pool_rpool,0,a)" 12 minutes
"bootfs rpool/ROOT/opensolaris-1" nearly instantaneous
"kernel$ /platform/i86pc/kernel/$ISADIR/unix -B $ZFS-BOOTFS -v" 3 seconds
"module$ /platform/i86pc/boot_archive" 3 seconds
"boot" After >80 minutes, still had not booted.  I didn't notice any
significant disk activity, but I didn't sit and watch it all the way.

What can I do to diagnose the Grub problem, and hopefully speed up
booting?  Would rearranging the disks in some order help?  I also have
another disk which I could mirror with the existing rpool disk if that
would help.

I didn't have this problem under 2008.05, it appears to be
2008.11-specific.  I've upgraded to the b106 kernel from the -dev
repository.

Thanks!
Will
