MPDEV_REMOTE

   (Alpha and Integrity servers) MPDEV_REMOTE enables MSCP served
   paths to become members of a multipath set when set to ON (1).
   When set to OFF (0),  only local paths to a SCSI or Fibre Channel
   device is used in the formation of additional multipath sets.
   However, setting this parameter to OFF does not have any effect
   on existing multipath sets that have remote paths.

   To use multipath failover to a served path, MPDEV_REMOTE must
   be enabled on all systems that have direct access to shared
   SCSI/Fibre Channel devices. The first release to provide this
   feature is OpenVMS Alpha Version 7.3-1. Therefore, all nodes
   on which MPDEV_REMOTE is enabled must be running OpenVMS Alpha
   Version 7.3-1 (or later).

   If MPDEV_ENABLE is set to OFF (0), the setting of MPDEV_REMOTE
   has no effect because the addition of all new paths to multipath
   sets is disabled. The default is ON.
