The reason why you can't specify size in mirrors for jumpstart is that
the two disks may have different geometry so the cylinder size and
number of cylinders are different.

You shouldn't specifiy c1t0d0s2 and c1t1d0s2 in your jumpstart profile.
They represent the while disk.

Check script doesn't accept this because it doesn't know which
'existing' slice to use (c1t0d0s0 or c1t1d0s0).

Once it failed, run the jumpstart in dryrun mode to provide more debug
information and it will tell you which jumpstart line has the problem.
# /usr/sbin/install.d/pfinstall -D <name of the profile>
(Usually your config files directory will be mounted under /tmp/<xxx>
directory)

It should work. If your disks are different use the smaller slice
between c1t0d0s0 or c1t1d0s0 as the primary submirror for your mirror.
How do you convert the size from cylinders to MB? For example fdisk
command will tell you the size of a cylinder
# fdisk /dev/rdsk/c1d0p0
Total disk size is 30400 cylinders
Cylinder size is 16065 (512 byte) blocks
Cylinders
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 Active Solaris2 7 30399 30393 100
2 Diagnostic 1 6 6 0
In this case, So the cylinder size is 16065 * 512 = 8225280 bytes and
which is between 7 and 8 MB.
The size of Solaris partition is 30393 * 8225280 = 238409 MB
