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.
Note - The format utility uses the term partition instead of slice.
For more information, see How to Obtain Administrative Rights in System Administration Guide: Security Services.
# format
A numbered list of disks is displayed.
Specify disk (enter its number):1
format> partition
partition> print
partition> q format> q #
If the screen output shows that no slice sizes are assigned, the disk probably does not have slices.
Example 11-4 Displaying Disk Slice Information
The following example displays slice information for a disk with a VTOC label.
# format Searching for disks...done Specify disk (enter its number):1 Selecting c0t0d0 format> partition partition> print Current partition table (original): Total disk cylinders available: 8892 + 2 (reserved cylinders) Part Tag Flag Cylinders Size Blocks 0 root wm 1110 - 4687 1.61GB (0/3578/0) 3381210 1 swap wu 0 - 1109 512.00MB (0/1110/0) 1048950 2 backup wm 0 - 8891 4.01GB (0/8892/0) 8402940 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 unassigned wm 0 0 (0/0/0) 0 7 home wm 4688 - 8891 1.89GB (0/4204/0) 3972780 partition> q format> q #
For a detailed description of the slice information in these examples, see Chapter 10, Managing Disks (Overview).
The following example shows the slice information for a disk with an EFI label.
