By default, TPD-controlled enclosures use pseudo device names based on the TPD-assigned node names. If you change the device naming to native, the devices are named in the same format as other VxVM devices. The devices use either operating system names (OSN) or enclosure-based names (EBN), depending on which naming scheme is set.
To change device naming for TPD-controlled enclosures
For disk enclosures that are controlled by third-party drivers (TPD) whose coexistence is supported by an appropriate ASL, the default behavior is to assign device names that are based on the TPD-assigned node names. You can use the vxdmpadm command to switch between these names and the device names that are known to the operating system:
# vxdmpadm setattr enclosure enclosure tpdmode=native|pseudo
The argument to the tpdmode attribute selects names that are based on those used by the operating system (native), or TPD-assigned node names (pseudo).
The use of this command to change between TPD and operating system-based naming is illustrated in the following example for the enclosure named EMC0. In this example, the device-naming scheme is set to OSN.

If tpdmode is set to native, the path with the smallest device number is displayed.
