Subdisks are contiguous blocks of space. Subdisks provide the basic building blocks for the VxVM software plexes and volumes, creating the VxVM software basic unit of storage allocation. Subdisks are virtual objects.
The following characteristics apply to subdisks:
- Subdisk storage is allocated from the public region of a VxVM software disk.
- A VxVM software disk can be subdivided into one or more subdisks. Multiple subdisks cannot overlap.
- Space on a VxVM software disk not allocated to a subdisk is considered free space.
Subdisk names are based on the VxVM software disk name where they reside, appended with an incremental numeric identifier.
