formating using another disk
# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s – /dev/rdsk/c0t2d0s2

Install boot block
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t2d0s0

A fairly typical layout is

0. /
1.  swap
2. whole disk
3.  /var
4. /data

If the system has has a database locally and there is a need for a bit of extra speed then /data can always be put on the faster part of the disk. Not to many systems swap much anymore since there is the ability to put in as much memory as is needed. Although if needed a seperate filesystem can be created for a swap partition.
0. /data
1. /
