SET PREFERRED PATH
SET PREFERRED_PATH is a DCL command that access to a MSCP/TMSCP class device may be available to an OpenVMS node from more than one host or storage controller. Use the SET PREFERRED_PATH command to specify a particular host or preferred path to access a specific MSCP class disk or TMSCP class tape device. If a preferred path is specified, the normal OpenVMS path selection process is modified to select the user-specified path over other available paths, assuming the user-specified path is available. This command is only meaningful for MSCP/TMSCP class devices that have more than one path available.
