Dynamic Multi-Pathing (DMP) is a component of SF. DMP supports Veritas Volume Manager (VxVM) volumes on DMP metadevices, and Veritas File System (VxFS) file systems on those volumes.

DMP can also provide multi-pathing functionality for the native operating system volumes and file systems on DMP devices.

For more information on using DMP with native devices, see the Dynamic Multi-Pathing Administrator's Guide.

After you install SF for the first time, use the following procedure to enable DMP support for native devices.

If DMP native support for native devices is enabled on a system before you upgrade SF, DMP native support is maintained when SF is upgraded.
