    partition> print
  6. Start the modification process.

  7. Set the disk to all free hog.

    When adding a system disk, you must set up slices for:

    • root (slice 0) and swap (slice 1) and/or

    • /usr (slice 6)

    After you identify the slices, the new partition table is displayed.

    If you don't want the current partition table and you want to change it, answer no and go to Step 6.

  11. Name the partition table.

    Enter table name (remember quotes): "partition-name"


    Is the name for the new partition table. 

  12. Label the disk with the new partition table when you have finished allocating slices on the new disk.

    Ready to label disk, continue? yes
  13. Quit the partition menu.

    partition> quit
  14. Verify the new disk label with verify command.

    format> verify
  15. Quit the format menu.
