Changing the disk-naming scheme

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

The default naming scheme is enclosure-based naming (EBN). When you install or upgrade a Storage Foundation product, the naming scheme is set to enclosure-based naming, with the following exception. If you explicitly set the naming scheme for an existing installation to operating system-based naming, the setting is preserved when you upgrade. That is, if you used the vxddladm set namingscheme=osn command for the existing installation, the upgraded 5.1 product retains the operating system-based naming.
