Layered Volumes
A layered volume is a virtual VERITAS Volume Manager object that is built on top of other
volumes. The layered volume structure tolerates failure better and has greater
redundancy than the standard volume structure. For example, in a striped-mirror layered
volume, each mirror (plex) covers a smaller area of storage space, so recovery is quicker
than with a standard mirrored volume.
