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 Array Support Library (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_name 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.

  # vxdisk list

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