HP CIFS File Locking Interoperation

8.4 Veritas File Server Edition

Veritas markets a UNIX/NT integration product called File Server Edition that runs on Sun

SPARC Solaris servers. File Server Edition consists of the Veritas File System, Veritas

Volume Manager, Veritas Quicklog, and Samba.

Veritas File Edition literature does not reference file locking capabilities. However, since it

is essentially Samba bundled with other Veritas products, we can reasonably conclude that

the file locking behavior is similar to CIFS/9000 (which is based upon Samba 2.0.6), minus

the planned enhancements.

Based upon Samba documentation, Veritas provides the following file locking ability:

Mandatory Share Mode (Open Mode) Veritas FSE
