Features implemented using multi-volume support
The following features can be implemented using multi-volume support:
Controlling where files are stored can be selected at multiple levels so that specific files or file hierarchies can be assigned to different volumes. This functionality is available in the Veritas File System SmartTier feature.
See About SmartTier.
Placing the VxFS intent log on its own volume to minimize disk head movement and thereby increase performance.
On HP-UX and Solaris:
This functionality can be used to migrate from the Veritas QuickLog™ feature.
Separating Storage Checkpoints so that data allocated to a Storage Checkpoint is isolated from the rest of the file system.
Separating metadata from file data.
Encapsulating volumes so that a volume appears in the file system as a file. This is particularly useful for databases that are running on raw volumes.
Guaranteeing that a dataonly volume being unavailable does not cause a metadataok volume to be unavailable.
See Volume availability.
To use the multi-volume file system features, Veritas Volume Manager must be installed and the volume set feature must be accessible. The volume set feature is separately licensed.
