Open console and start with this :
bash-3.00# format
It gives the following output.

Specify disk (enter its number):
Check out, AVAILABLE DISK SELECTIONS. Now, I have only one disk (c0d0). Select the ‘0’ (Zero) no. disk to make partitioned in it.
Specify disk (enter its number): 0
It will give the following output.

Checkout the table. No 0, 1, 2,8 and 9 is not usable. no. 3 is not usable as already created a partition there. 4,5,6 and 7 is available to make partition. So, I have selected 4.
partition> 4
It will give following output :

Enter partition id tag[unassigned]:
Keep partition id and permission flags empty.
Enter partition id tag[unassigned]:
Enter partition permission flags[wm]:
Enter new starting cyl[0]:
Now, check previous partition of no. 4. It is number 3. Its Cylinders count ended at 1672. So, we will start from 1673. (If there is no no. 3 that i created previously, then we would have look for part no. 1. Not 2, because it is not usable, it represents whole disk size).
Now enter 1673
Enter new starting cyl[0]: 1673
and partition size 500mb.
Enter partition size[0b, 0c, 1673e, 0.00mb, 0.00gb]: 500mb
Now enter ‘label’ to confirm your partition.
partition> label
Ready to label disk, continue? y
Now, again see your partitioning summary.

Now, we have to mount this partition.
Create a directory in root directory.
bash-3.00# cd /
bash-3.00# mkdir oracle
Our partition is at ‘/dev/dsk/c0d0s4’. We will mount it to previously created oracle directory.
bash-3.00# mount /dev/dsk/c0d0s4 /oracle
Check newly created partition.
bash-3.00# cd /oracle/
