File system links make physical file systems accessible through the CNS. A file system link can be associated with either the root directory or a subdirectory in a physical file system. After created, a file system link is displayed as a directory in the CNS. The directory name seen by a network client will be the name given to the file system link. A network client navigating through CNS and into a file system link will see the contents of the directory that was linked.
  1. Navigate to Home > File Services > CNS to display the CNS page.
  2. Click Add Link to display the Link File System page.


  3. In the Link Name text box, enter a name for the link.
  4. In the From CNS Directory options box, select a location in the CNS tree to place the link.
  5. To allow files or cross file system links from remote file systems to be read cached, go to the Remote Read Cache list, and select one of the following:
    Note: For information about read caching, see the File Services Administration Guide.
    • Cache all files. Allows caching of files from a file system hosted by an EVS on a remote cluster node, and files accessed by local links to a remote file system (cross file system links). A remote cluster node is a node other than the one to which the client is connected.
    • Cache cross file system links. Allows only cross file system links to be cached.
    Note: When the link being added is for a file system in an EVS that has an EVS individual namespace, remote read caching is not available.

    To disallow read caching of files from remote file systems, do not change the default selection of Do not cache files.

  6. To allow files or cross file system links from local file systems to be read cached, go to the Local Read Cache list, and select one of the following:
    • Cache all files. Allows caching of files from file systems on the same server/node as the read cache, and files accessed by local links to a remote file system (cross file system links). The remote file system might be a remote server or storage device.
    • Cache cross file system links. Allows only cross file system links to be cached.
    To disallow read caching of files from remote file systems, do not change the default selection of Do not cache files.
