Volume application programming interfaces

The volume APIs can be used to add volumes to a file system, remove volumes from a file system, list which volumes are in a file system, and retrieve information on usage and availability of space in a volume.

Multi-volume file systems can only be used with VxVM volume sets. Volume sets are administered via the vxvset command.
