## Overview

ONTAP allows both CIFS and NFS to access the same datastore. This datastore can contain symbolic links which are files, created by UNIX clients. It contains a reference to another file or directory. If an SMB client accesses a symbolic link, it is redirected to the target file or directory that the symbolic link refers to. The symbolic links can point to files within the volume that contain the share, or to files that are contained in other volumes on the Storage Virtual Machine (SVM), or even to volumes contained on other SVMs.

There are two types of symbolic links:

- Relative A relative symbolic link contains a reference to the file or directory relative to its parent directory. Therefore, the path of the file it is referring to should not begin with a backslash (/). If you enable symbolic links on a share, relative symbolic links work without UNIX symlink mapping.
- Absolute An absolute symbolic link contains a reference to a file or directory in the form of an absolute path. Therefore, the path of the file it is referring to should begin with a backslash (/). An absolute symbolic link can refer to a file or directory within or outside of the file system of the symbolic link. If the target is not in the same local file system, the symbolic link is called a "widelink". If the symbolic link is enabled on a share and absolute symbolic links do not work right away, the mapping between the UNIX path of the symbolic link to the destination CIFS path must be created. When creating absolute symbolic link mappings, locality could be either "local" or "widelink" and it must be specified. If UNIX symlink mapping is created for a file or directory which is outside of the local share but the locality is set to "local", ONTAP does not allow access to the target. A UNIX symbolic link support could be added to SMB shares by specifying the unix_symlink property during the creation of SMB shares or at any time by modifying the existing SMB unix_symlink property. UNIX symbolic link support is enabled by default.

## Examples

### Creating a UNIX symlink mapping for CIFS shares

To create UNIX symlink mappings for SMB shares, use the following API. Note the return_records=true query parameter used to obtain the newly created entry in the response.

    from netapp_ontap import HostConnection
    from netapp_ontap.resources import CifsSymlinkMapping

    with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
        resource = CifsSymlinkMapping()
        resource.svm.name = "vs1"
        resource.svm.uuid = "000c5cd2-ebdf-11e8-a96e-0050568ea3cb"
        resource.target.home_directory = False
        resource.target.locality = "local"
        resource.target.path = "/dir1/dir2/"
        resource.target.server = "cifs123"
        resource.target.share = "sh1"
        resource.unix_path = "/mnt/eng_volume/"
        resource.post(hydrate=True)
        print(resource)

        )
        resource.delete()

## Classes

`class CifsSymlinkMapping (*args, **kwargs)`

  ONTAP allows for both CIFS and NFS access to the same datastore. This datastore can contain symbolic links created by UNIX clients which can point anywhere from the perspective of the UNIX client. To Access such UNIX symlink from CIFS share, we need to create a CIFS symbolic link path mapping from a UNIX symlink and target it as a CIFS path.

  Initialize the instance of the resource.

  Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

      MyResource(name='foo').name == 'foo'

  ## Args

  `*args`
    Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
  `**kwargs`
    each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

  ### Ancestors

  - Resource

  ### Static methods

  `def count_collection(*args, connection: HostConnection = None, **kwargs) -> int`

    Retrieves UNIX symbolic link mappings for CIFS clients.

    ### Related ONTAP commands

    - `vserver cifs symlink show`

    ### Learn more

    - `DOC /protocols/cifs/unix-symlink-mapping`

    Fetch a count of all objects of this type from the host.

    This calls GET on the object to determine the number of records. It is more efficient than calling get_collection() because it will not construct any objects. Query parameters can be passed in as kwargs to determine a count of objects that match some filtered criteria.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the count of bars for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host. These query parameters can affect the count. A return_records query param will be ignored.

    ## Returns

    On success, returns an integer count of the objects of this type. On failure, returns -1.

    ## Raises

    `NetAppRestError`: If the API call returned a status code >= 400, or if there is no connection available to use either passed in or on the library.

  `def delete_collection(*args, body: typing.Union = None, connection: HostConnection = None, **kwargs) -> NetAppResponse`

    Deletes the UNIX symbolic link mapping for CIFS clients.

    ### Related ONTAP commands

    - `vserver cifs symlink delete`

    ### Learn more

    - `DOC /protocols/cifs/unix-symlink-mapping`

    Delete all objects in a collection which match the given query.

    All records on the host which match the query will be deleted.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to delete the collection of bars for a particular foo, the foo.name value should be passed.
    `body`
      The body of the delete request. This could be a Resource instance or a dictionary object.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be deleted.

    ## Returns

    A `NetAppResponse` object containing the details of the HTTP response.

    ## Raises

    `NetAppRestError`: If the API call returned a status code >= 400

  `def find(*args, connection: HostConnection = None, **kwargs) -> Resource`

    Retrieves UNIX symbolic link mappings for CIFS clients.

    ### Related ONTAP commands

    - `vserver cifs symlink show`

    ### Learn more

    - `DOC /protocols/cifs/unix-symlink-mapping`

    Find an instance of an object on the host given a query.

    The host will be queried with the provided key/value pairs to find a matching resource. If 0 are found, None will be returned. If more than 1 is found, an error will be raised or returned. If there is exactly 1 matching record, then it will be returned.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to find a bar for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host.

    ## Returns

    A `Resource` object containing the details of the object or None if no matches were found.

  `def get_collection(*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> typing.Iterable`

    Retrieves UNIX symbolic link mappings for CIFS clients.

    ### Related ONTAP commands

    - `vserver cifs symlink show`

    ### Learn more

    - `DOC /protocols/cifs/unix-symlink-mapping`

    Fetch a list of all objects of this type from the host.

    This is a lazy fetch, making API calls only as necessary when the result of this call is iterated over. For instance, if max_records is set to 5, then iterating over the collection causes an API call to be sent to the server once for every 5 records. If the client stops iterating before getting to the 6th record, then no additional API calls are made.

    ## Args

    `*args`
      Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the collection of bars for a particular foo, the foo.name value should be passed.
    `connection`
      The `HostConnection` object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
    `max_records`
      The maximum number of records to return per call
    `**kwargs`
      Any key/value pairs passed will be sent as query parameters to the host.

    ## Returns

    A list of `Resource` objects

    ## Raises

    `NetAppRestError`: If there is no connection available to use either passed in or on the library. This would be not be raised when get_collection() is called, but rather when the result is iterated.
