recognized as one or more disk sets, and is the minimum unit used when backing
up or restoring data.

disk set

For Application Agent in a dynamic disk configuration, a disk set is a group
consisting of one or more dynamic disks and one or more logical volumes
allocated to the dynamic disks.

dynamic disk

A function for creating a disk group. Note, however, that the physical disks that
make up a disk group or disk set are sometimes called dynamic disks. You can
join multiple dynamic disks to create a logical volume (dynamic volume) or split
a dynamic disk into multiple logical volumes. Application Agent supports Veritas
Storage Foundation dynamic disk configurations.

dynamic volume

A logical volume created by joining or splitting one or more dynamic disks and
then assigning them.
