Client users can create MVS™ data sets from a client system using the NFS. The default data set creation attributes specified by the system administrator are used to create MVS data sets, unless the user overrides them. These attributes determine how the MVS data sets are structured and where they are stored. Client users can override the default data set creation and processing attributes for a mount point when issuing the mount command. In addition, you can override these attributes at file creation time.
