If you have been using a map file on another system and want to use it on z/OS UNIX, you will have to use a conversion utility to reformat it. If you want to use a map file with syntax different from that supported by z/OS UNIX, such as a map file from another type of system, you can implement a conversion utility that converts the file to syntax supported by z/OS UNIX. Then you can direct the automount utility to run it and use the output of your conversion utility as the map file. For more information, see the automount command in z/OS UNIX System Services Command Reference.
