Splitting a Subdisk
This procedure divides a subdisk into two or more smaller subdisks.
Once split, the smaller subdisks can be moved elsewhere or rejoined
later. This is useful for reorganizing volumes and/or improving
performance.
You can use the Object View window (Disk Groups > Object View) or the
Volume to Disk Mapping window (Disk Groups > Disk/Volume Map) to
view the subdisks in a disk group. You can use the Volume Layout
Details window (Volumes > Show Layout) to view subdisks in a specific
volume.

Step 2. Choose Subdisks > Split (Selected menu) or Subdisk Split (Command
