About Veritas Dynamic Multi-Pathing

Veritas Dynamic Multi-Pathing (DMP) provides multi-pathing functionality for the operating system native devices configured on the system. The product creates DMP metadevices (also known as DMP nodes) to represent all the device paths to the same physical LUN.

In earlier releases, DMP was only available as a feature of Veritas Volume Manager (VxVM). DMP supported VxVM volumes on DMP metadevices, and Veritas File System (VxFS) file systems on those volumes.

On AIX, HP-UX, and Linux:

Symantec now extends DMP metadevices to support OS native logical volume managers (LVM). You can create LVM volumes and volume groups on DMP metadevices.

On Solaris:

Symantec now extends DMP metadevices to support ZFS. You can create ZFS pools on DMP metadevices.

Note:

Veritas Dynamic Multi-Pathing is a standalone product. Support for dynamic multi-pathing is also included in Veritas Storage Foundation products.

Before you install this product, review the Veritas Dynamic Multi-Pathing Release Notes.

To install the product, follow the instructions in the Veritas Dynamic Multi-Pathing Installation Guide.
