You can use the format utility to check whether or not 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. See "SPARC: How to Create Disk Slices and Label a Disk" or "IA: How to Create Disk Slices and Label a Disk" for information on creating disk slices.
The format utility uses the term partition in place of slice.

Enter the format utility.
# format |
Identify the disk for which you want to display slice information by selecting a disk listed under AVAILABLE DISK SELECTIONS.
Specify disk (enter its number):1 |
Enter the partition menu by typing partition at the format> prompt.
format> partition |
Display the slice information for the current disk drive by typing print at the partition> prompt.
partition> print |
Exit the format utility by typing q at the partition> prompt and typing q at the format> prompt.
partition> q format> q # |
Verify 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 /dev/dsk/c0t3d0.

See Chapter 28, Disk Management (Overview) for a detailed description of the slice information displayed in these examples.
The following example displays the slice information on disk /dev/dsk/c0t0d0.
