Joining Subdisks
This procedure joins two or more subdisks together to form a single,
larger subdisk. Subdisks can only be joined together if they belong to the
same volume and occupy adjacent regions of the same disk and mirror.
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 > Join (Selected menu) or Subdisk Join (Command

• Only contiguous subdisks on the same disk can be joined.
• The subdisks to be joined must belong to the same volume and mirror.
• For a striped volume, the subdisks must be in the same column.
• The joined subdisk name can be the name of one of the subdisks being
joined.
