Changing the disk device naming scheme

You can either use enclosure-based naming for disks or the operating system's naming scheme. DMP commands display device names according to the current naming scheme.

The default naming scheme is enclosure-based naming (EBN).

When you use Dynamic Multi-Pathing (DMP) with native volumes, the disk naming scheme must be EBN, the use_avid attribute must be yes, and the persistence attribute must be set to yes.
