<h1>VxVM (Veritas Volume Manager)</h1>

VxVM (Veritas Volume Manager) organizes data  blocks on physical disks
into logical  volumes,   which  makes disk   data  independent of  the
physical pathname of  the  disk drives. VxVM  is  also responsible for
disk  concatenation,  striping, and volume  replication (mirroring) to
coordinate  all nodes in   the cluster.   For replicated  volumes, the
volume manager is responsible for masking bad  block errors and failed
disks to   the database system.   The volume  manager also coordinates
recovery of a mirrored volume after a failed disk is replaced. <p>

VxVM does not support shared disk groups and is used with
<a href="sc/xps">Informix XMP</a> databases.
