How to Display Disk Slice Information

  1. Become superuser or assume an equivalent role.

  2. Invoke the format utility.


    # format

  3. 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

  4. Select the partition menu.


    format> partition

  5. Display the slice information for the current disk drive.


    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.
