How to Partition a Hard Drive in Solaris
1) The format utility is used for partitioning Solaris UFS based file systems. It is an interactive menu driven utility.
 
# format

	0. c0t0d0 <SUN2.1G cyl 2733 alt 2 hd 19 sec 80>
	/devices/pci@1f,0/pci@1,1/ide@3/dad@0,0
	1. c0t1d0 <SUN2.1G cyl 2733 alt 2 hd 19 sec 80>
	/devices/pci@1f,0/pci@1,1/ide@3/dad@0,0
2) Be sure you select the right disk. Disk 1 is chosen here because it is not currently in use. You CAN'T partition a disk with mounted filesystems.
 
Specify disk (enter its number): 1
selecting c0t1d0

[disk formatted]
3) You are taken into the format interactive menu. There are many options available within this menu. Many, however, are not used on a daily basis. 
FORMAT MENU:
        disk       - select a disk
        type       - select (define) a disk type
        partition  - select (define) a partition table
        current    - describe the current disk
        format     - format and analyze the disk
        repair     - repair a defective sector
        label      - write label to the disk
        analyze    - surface analysis
        defect     - defect list management
        backup     - search for backup labels
        verify     - read and display labels
        save       - save new disk/partition definitions
        inquiry    - show vendor, product and revision
        volname    - set 8-character volume name
        !<cmd>     - execute <cmd>, then return
        quit
4) The "partiton" option is responsible for partitioning a disk. Type "partition" at the format interactive prompt.
 
format> partition
5) You are now taken to the partition interactive menu. Notice the change in the prompt.
 

PARTITION MENU:
        0      - change `0' partition
        1      - change `1' partition
        2      - change `2' partition
        3      - change `3' partition
        4      - change `4' partition
        5      - change `5' partition
        6      - change `6' partition
        7      - change `7' partition
        select - select a predefined table
        modify - modify a predefined partition table
        name   - name the current table
        print  - display the current table
        label  - write partition map and label to the disk
        !<cmd> - execute <cmd>, then return
        quit
6) The "modify" option is used to partition an entire disk. Type "modify" at the partition prompt.
 
partition> modify
7) There are two ways to partition an entire disk. The first is to calculate by hand the cylinder offsets of each partition. This can lead to overlapping filesystems which will corrupt data. The "All Free Hog" option enables partitioning of a disk by size (b, kb, mb, gb) and the utility calculates the required cylinder offsets.
 
Select partitioning base:
        0. Current partition table (original)
        1. All Free Hog
8) Select the "All Free Hog" option.
 
Choose base (enter number) [0]? 1
9) The "All Free Hog" utility will give a printout of the current size of the disk (reported by "Part 2").  Select "yes" to confirm that this is the correct disk.
 
Part      Tag    Flag     Cylinders         Size            Blocks
  0       root    wm       0                0         (0/0/0)            0
  1       swap    wu       0                0         (0/0/0)            0
  2     backup    wu       0 - 13324        6.00GB    (13325/0/0) 12592125
  3 unassigned    wm       0                0         (0/0/0)            0
  4 unassigned    wm       0                0         (0/0/0)            0
  5 unassigned    wm       0                0         (0/0/0)            0
  6        usr    wm       0                0         (0/0/0)            0
  7 unassigned    wm       0                0         (0/0/0)            0
  
Do you wish to continue creating a new partition
table based on above table[yes]? yes
10) Since free hog does the math for you based on the sizes you specify,  any left over space will be made into partition 6. 
Free Hog partition[6]? 6
 
11) Enter sizes for each partition. If you do not want to use a specific partition, then just press
"enter" and the slice will be skipped.
 
Enter size of partition '0' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
Enter size of partition '1' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
Enter size of partition '3' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
Enter size of partition '4' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
Enter size of partition '5' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
Enter size of partition '7' [0b, 0c, 0.00mb, 0.00gb]: 1000mb
12) Upon completion of the partitioning, the "All Free Hog" utility will print the new partitioning scheme.
Notice that you were never prompted to fenter a size for partition 6. However, a size has been
assigned. This is the "All Free Hog" utility taking all leftover space and placing it on partition 6.

  7 unassigned    wm   11157 - 13324     1000.37MB    (2168/0/0)   2048760
13) Confirm the current partitioning scheme by typing "yes".
 
Okay to make this the current partition table[yes]?  yes
14) Give the partitioning table a name.
 
Enter table name (remember quotes): "darren"
15) Label the disk. This step is the "point of no return". Up until this step, you can exit out of the format utility without making any changes to the disk.
 
Ready to label disk, continue? y
16) Quit out of the partitioning menu.
 
partition> quit
17) From within the format menu, save the partitioning table to a file for later use. Save the label to the /etc/format.dat system file. 
format> save
Saving new disk and partition definitions
Enter file name["./format.dat"]: /etc/format.dat
18) Exit it out of the format menu to complete the exercise 
format> quit
