Veritas File System (VxFS) I/O controls the access of data on a VxFS file system. VxFS APIs are provided for freezing and thawing file systems, administering caching advisories, and administering extent attributes.

Note:

Unlike the other VxFS APIs described in this document, the APIs described in this chapter are available in previous releases of VxFS on all platforms. The exception is the API that provides concurrent I/O access through the VxFS caching advisories, which is available on VxFS 4.1 and later releases.
