protect Windows clients that have locked files from UNIX/NFS and PC-NFS processes that implement the byte range advisory locking protocol. CIFS/9000 will not protect Windows clients from processes that do not adhere to the advisory locking protocol. CIFS/9000 has a planned enhancement to provide this capability.
CIFS/9000 provides locking interoperability between Windows clients with Mandatory Share Mode (Open Mode) locks and UNIX/NFS or PC-NFS clients as of the September 2001 HP-UX application Release15.
Currently, CIFS/9000 will not send Windows Clients an oplock break when a UNIX/NFS or PC-NFS client requests concurrent file access. CIFS/9000 has a planned enhancement to provide this capability.
At first release in March of 2000, CIFS/9000 provides comprehensive Windows client file locking interoperability, and byte-range locking interoperability for UNIX/NFS and PC-NFS clients. At the September 2001 HP-UX Application Release, Windows Mandatory Share Mode (Open Mode) locking interoperability UNIX/NFS advisory locking is added. With the addition of non-locking protection and oplocks in future enhancements, CIFS/9000 will meet, and in most cases exceed, its competitors Windows-UNIX/NFS interoperability file system products.
