SPARC: How to Create Disk Slices and Label a Disk
-
Become superuser.
-
# format
A list of available disks is displayed.
-
Enter the number of the disk that you want to repartition from the list displayed on your screen.
Specify disk (enter its number): disk-number
disk-number
Is the number of the disk that you want to repartition.
-
Go into the partition menu (which lets you set up the slices).
format> partition
-
Display the current partition (slice) table.
partition> print
-
Start the modification process.
partition> modify
-
Set the disk to all free hog.
Choose base (enter number) [0]? 1
See "Using the Free Hog Slice" for more information about the free hog slice.
-
Create a new partition table by answering y when prompted to continue.
Do you wish to continue creating a new partition table based on above table[yes]?y
-
Identify the free hog partition (slice) and the sizes of the slices when prompted.
When adding a system disk, you must set up slices for:
-
root (slice 0) and swap (slice 1) and/or
-
/usr (slice 6)
After you identify the slices, the new partition table is displayed.
-
-
Make the displayed partition table the current partition table by answering y when asked.
Okay to make this the current partition table[yes]? y
If you don't want the current partition table and you want to change it, answer no and go to Step 6.
-
Name the partition table.
Enter table name (remember quotes): "partition-name"
partition-name
Is the name for the new partition table.
-
Label the disk with the new partition table when you have finished allocating slices on the new disk.
Ready to label disk, continue? yes
-
Quit the partition menu.
partition> q
-
Verify the disk label using the verify command.
format> verify
-
Quit the format menu.
format> q
SPARC: Example--Creating Disk Slices and Labeling a System Disk
The following example uses the format utility to divide a 200-Mbyte disk into two slices: one for the root (/) file system and one for the swap area.

Where to Go From Here
After you create disk slices and label the disk, you can create file systems on the disk. Go to "SPARC: How to Create File Systems".
