How to Display Disk Slice Information in Solaris

You might need to display disk slice information if the disk is intended to be used for the ZFS root pool. It must also include a SMI label.

1. Become an administrator.
2. Invoke the format utility.

   # format

   A numbered list of disks is displayed.
3. Type the number of the disk for which you want to display slice information.

   Specify disk (enter its number):1

4. Select the partition menu.

   format> partition 

5. Display the slice information for the selected disk.

   partition> print

6. Exit the format utility.

   partition> q
   format> q

7. 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.
