In addition to mapping between the workstation and the MVS file systems, the z/OS NFS server might be different from non-MVS NFS servers in other ways, including these differences:

• Selection of an MVS data storage format
• File size determination and time stamps
• Ownership and permissions
• Selecting MVS file systems versus z/OS UNIX file systems
• State
• File reading and writing
  • Random access to files
  • Cached data writing
• Case sensitivity–maplower, nomaplower
• Selection of text or binary processing modes–text, binary
  • Binary processing mode
  • Text processing mode
• Number representation
• Partial record identification
• Access to migrated files–retrieve, noretrieve; wait, nowait
• Access to system-managed migrated data sets
• File handle refresh
• File extension mapping
