Thanks to Lance and Anatoliy who helped me with the answer:
Lance gave me this excellent answer with all the info I needed.
Anatoliy and Ken notes to check the /etcc/vfstab on the second disk or it
wont be useable to boot from.
Thanks everyone!
SOLUTION:
do an ls -l of /dev/dsk/c1t1d0s0
should point to something like this:
../../devices/pci@9,600000/SUNW,qlc@2/fp@0,0/disk${WWN},0:a
where ${WWN} is your worldwide name for that disk.
so your current boot device is:
/pci@9,600000/SUNW,qlc@2/fp@0,0/disk@w2100000c50dcffef,0:a (which is
c1t0d0s0)
your second disk will be whatever is after ../../devices from the ls -l of
/dev/dsk/c1t1d0s0
so then in prom do:
ok nvalias disk1 ${string}
where ${string} is like /pci@9,600000/SUNW,qlc@2/fp@0,0/disk${WWN},0:a
(that you got from ls -l /dev/dsk/c1t1d0s0)
you should also be able to get the disk device path from:
ok show-disks
but i like to get it from the OS side, just my preference

Hi Gurus,
I have some sun sparc servers (280s, 480s) running solaris 8.
Instead of mirroring the root drives, i use ufsdump piped to ufsrestore,
prtvtoc and fmthard to copy the root disk (c1t0d0s0) to another drive in my
server (c1t1d0s0).
This works fine, but I have never tried booting off the second disk to
test.
My question is this:
How would I know what device to boot from at the ok prompt if i want to
boot off the second disk?
If the answer is to "boot disk1", what if there was no devalias of disk1 or
disk0 already setup.
How would I know the full device path to use?
Thank you in advance.
Here are my OK prompt settings:
