HI Prashant,
Do you have any specific suporting doc which talking about VXFS veritas file system
No, not specifically since we state support for SQL Anywhere in terms of the operating system as a whole rather than the specific file systems that can be used with the operating system. See our Supported Platforms page: SAP SQL Anywhere Supported Platforms and Engineering Support Status
SQL Anywhere uses standard file POSIX calls on Linux / UNIX, so again, the underlying file system type just needs to support our file semantics (write-through and write-ordering).
