Exports data set

To allocate and modify the exports data set, perform the following tasks.

Allocate a fixed block partitioned data set or a fixed block sequential data set with record length of 80.
Copy the sample member GFSAPEXP from the prefix.NFSSAMP data set into the allocated data set.
Modify the sample exports data set to suit your installation. Sample exports data set shows the sample exports data set.
Specify this exports data set for the EXPORTS DD statement in the MVSNFS cataloged procedure.

The exports data set contains entries for directories that can be exported to clients. It is used by the server to determine which data sets' high-level qualifiers or z/OS UNIX directories can be mounted by a client in a read or write mode.

Note: You cannot specify exporting a "parent directory" or a subdirectory of an exported directory. For example, if you specify DIR1 in the exports data set, DIR1 and all its subdirectories are exported. You cannot specify any subdirectories under DIR1 in the exports data set.
