DCE LFS filesets are created with the fts create command. Non-LFS filesets are created in the local operating system and registered in DFS with the fts crfldbentry command. Mount points to the global namespace for both DCE LFS and non-LFS filesets are created with the fts crmount command.
The following topics discuss setting up a cell's root fileset, binary and configuration filesets, and user filesets. Information about fileset replication and the @sys and @host variables, which simplify cell administration, is also provided. (See Making Filesets and Aggregates Available for complete information about creating and mounting filesets; see Part 2 of this guide and reference for complete information about fts and other DFS commands.)
