You can use the format utility to check whether a disk has the appropriate disk slices. If you determine that a disk does not contain the slices you want to use, use the format utility to re-create them and label the disk. For information on creating disk slices, see SPARC: How to Create Disk Slices and Label a Disk or x86: How to Create Disk Slices and Label a Disk.
The format utility uses the term partition instead of slice.
Become superuser or assume an equivalent role.
Invoke the format utility.
# format |
Type the number of the disk for which you want to display slice information from the list displayed on your screen.
Specify disk (enter its number):1 |
Select the partition menu.
format> partition |
Display the slice information for the current disk drive.
partition> print |
Exit the format utility.
partition> q format> q # |
Verify the displayed slice information by identifying specific slice tags and slices.
If the screen output shows that no slice sizes are assigned, the disk probably does not have slices.
The following example displays slice information for disk with a VTOC label.

For a detailed description of the slice information in these examples, see Chapter 32, Managing Disks (Overview).
The following example shows the slice information on a disk with an EFI label.
