VxFS multi-volume system

VxFS_Checkpoint and VxVM are the only snapshot methods in Snapshot Manager that support the multi-volume file system (MVS) feature of VxFS 4.0.

The multi-volume file system feature requires a VxVM 4.0 volume set. With volume sets, you can group related volumes into one volume set, and mount a VxFS file system on it. This means that a VxFS file system can be mounted on more than one volume. This feature allows file systems to make best use of the different performance and availability characteristics of the underlying volumes. For example, file system metadata can be stored on volumes with higher redundancy, and user data on volumes with better performance.

For background and configuration assistance with multi-volume file systems, refer to the Veritas File System 4.0 Administrator's Guide and the Veritas Volume Manager 4.0 Administrator's Guide.
