Changing the disk device naming scheme

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

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

When you use DMP with native volumes, the disk naming scheme must be EBN, the use_avid attribute must be on, and the persistence attribute must be set to yes.


Devices with very long device names (longer than 31 characters) are represented by enclosure-based names regardless of the naming scheme. If the OS-based names include WWN identifiers, the device name displays with the WWN identifier as long as the device name is less than 31 characters. If any device name is longer than 31 characters, that device name displays with an enclosure name.
