After the SmartIO feature is configured, you can verify that the cache area is present and that caching is occurring.
For a VxFS cache area, the sfcache list command shows the caching mode for the file or directory. If the mode is not explicitly set, the file or directory inherits the caching mode of the mount point. If the mode is explicitly set for a file or directory, that value persists across remounts. The displayed caching mode may differ from the mode that is enabled for the mount point. The writeback mode is not enabled unless the file system is mounted in writeback mode. If a file or directory is set to writeback mode, but the file system is mounted in another mode, the file or directory inherits the caching mode of the mount point.
