Run solaris' fdisk over the disk to setup the partitioning correctly before
getting stuck into /usr/sbin/format to setup the slices. You cannot really
make use of more than one partition on a disk (scsi or ide) due to some issues
with the way Solaris handles partitions (as opposed to slices) on a disk,
so you if want to have multiple partitions (for multiple OSen) then just be
careful about what you expect to see from Solaris' point of view.
What you need to ensure is that if you are going to devote the disk to Solaris
(my _strong_ recommendation based on personal experience!) then you wipe the
partition table clean with fdisk and then ensure that cylinders 8 and 9 on
the disk are as per my c1d0p0 disk (see the format.out file and the others
which I've attached).
Incidentally, if you're running solaris for x86, have a look at GAG - a
freeware graphical bootloader http://raster.cibermillennium.com/gageng.htm
which I've been using with no issues for nearly two years.

actually, that's "probe-ide" from the OBP's ok> prompt. If you have a scsi
device then you'd use "probe-scsi-all" instead. Also, ensure you use a jumper
to set either master or slave -- I recall that you could get some interesting
behaviour with ide devices if you used cable select - but I'm pretty sure
that's been fixed by now....
