This file has been automatically generated based on the ONTAP REST API documentation.
Overview
This API is used to manage transfers on an existing SnapMirror relationship.
You can initiate SnapMirror operations such as "initialize", "update", "restore-transfer", and "abort" using this API on asynchronous SnapMirror relationship. On a synchronous SnapMirror relationship, you can initiate SnapMirror "initialize" operation. The GET for this API reports the status of both active transfers and transfers that have terminated within the past 24 hours.
For the restore relationships, the POST on transfers API triggers "restore-transfer". Successful completion of "restore" also deletes the restore relationship. If the "restore" fails, DELETE on relationships must be called to delete the restore relationship.
A transfer on an asynchronous SnapMirror relationship with Application Consistency Group endpoints expands the destination Application Consistency Group endpoint if the source Application Consistency Group endpoint is already expanded.
Classes
class SnapmirrorTransfer (*args, **kwargs)
-
SnapMirror transfer information
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
Static methods
def count_collection (*args, connection: HostConnection = None, **kwargs) -> int
-
Returns a count of all SnapmirrorTransfer resources that match the provided query
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 find (*args, connection: HostConnection = None, **kwargs) -> Resource
-
Retrieves the list of ongoing SnapMirror transfers for the specified relationship.

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.Raises
NetAppRestError
: If the API call returned more than 1 matching resource. def get_collection (*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> Iterable[Resource]
-
Retrieves the list of ongoing SnapMirror transfers for the specified relationship.

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
objectsRaises
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. def patch_collection (body: dict, *args, records: Iterable[_ForwardRef('SnapmirrorTransfer')] = None, poll: bool = True, poll_interval: Optional[int] = None, poll_timeout: Optional[int] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Args
body
