Identify the file type as either PIPE (a FIFO file) that is coded in combination with the PATH operand or as an HFS (hierarchical file system) specified in combination with the DSNAME operand. HFS indicates that the data set is an HFS data set which contains a z/OS® UNIX hierarchical file system. DSNTYPE does support other values (for example LIBRARY, PDS, EXTREQ, EXTPREF, LARGE, and BASIC), but these are not appropriate for HFS files.
