OK, a bit more and detailed info.
I've dropped back to making the second disk a 250Gb instead of a 750Gb 1)
because it's definitely supported in the ultra 24 where as I'm not sure about
the 750, 2) I'm not sure if there is still limitation in having boot files
within the first 1000 blocks (was it? is it?) 3) I'm not even sure if the
mirror actually worked if one drive was pulled when I had 2 x 250Gb set up
previously.
A little on physical to BIOS to OS drive mapping. There are 4 physical disk
slots 0 to 3, 4 BIOS HDDs, SATA:P1 to SATA:P4 of which I can designate the boot
order.
Phys => BIOS => OS
Slot 1 = SATA:P2 = c0d1s0
Slot 3 = SATA:P4 = c6d0s0
# zpool status rpool
pool: rpool
state: ONLINE
scrub: none requested
config:

c6d0s0 ONLINE 0 0 0

I still have the problem where I can't boot from c6d0s0 (with c0d1s0 removed).
I CAN boot from c6d0s0 if c0d1s0 is plugged in though.
The full error when booting off c6d0s0 (with c0d1s0 removed):
Booting 'Solaris 10 5/09 s10x_u7wos_08 x86'
finding (pool_rpool,1,a)

same as above but no ((hd1,1,a)
the zio_read_etc and checksum errors seem to be unrelated to my particular
problem as they appear for both booting and non booting drives.
So... any idea what I've missed or done wrong?
Thanks
