This file has been automatically generated based on the ONTAP REST API documentation.
Overview
FlexCache is a persistent cache of an origin volume. An origin volume can only be a FlexVol while a FlexCache is always a FlexGroup. The following relationship configurations are supported:
- Intra-Vserver where FlexCache and the corresponding origin volume reside in the same Vserver.
- Cross-Vserver but intra-cluster where FlexCache and the origin volume reside in the same cluster but belong to different Vservers.
- Cross-cluster where FlexCache and the origin volume reside in different clusters. FlexCache supports fan-out and more than one FlexCache can be created from one origin volume. This API retrieves and manages FlexCache configurations in the cache cluster.
FlexCache APIs
The following APIs can be used to perform operations related with FlexCache:
- GET /api/storage/flexcache/flexcaches
- GET /api/storage/flexcache/flexcaches/{uuid}
- POST /api/storage/flexcache/flexcaches
- DELETE /api/storage/flexcache/flexcaches/{uuid}
Examples
Creating a FlexCache
The POST request is used to create a FlexCache.
from netapp_ontap import HostConnection
from netapp_ontap.resources import Flexcache
with HostConnection("<mgmt-ip>", username="admin", password="password", verify=False):
resource = Flexcache()
resource.aggregates = [{"name": "aggr_1"}]
resource.name = "fc_333"
resource.origins = [{"svm": {"name": "vs_3"}, "volume": {"name": "vol_o1"}}]
resource.svm = {"name": "vs_1"}
resource.post(hydrate=True)
print(resource)
Flexcache(
{
"aggregates": [{"name": "aggr_1"}],
"origins": [{"svm": {"name": "vs_3"}, "volume": {"name": "vol_o1"}}],
"svm": {"name": "vs_1"},
"name": "fc_333",
}
)
curl -X POST "https://

### Retrieving FlexCache attributes
The GET request is used to retrieve FlexCache attributes. The object includes a large set of fields which can be expensive to retrieve. Most notably, the fields size, guarantee.type, aggregates, path, origins.ip_address, origins.size, and origins.state are expensive to retrieve. The recommended method to use this API is to filter and retrieve only the required fields.
```python

Classes
class Flexcache (*args, **kwargs)
-
Defines the cache endpoint of FlexCache.
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 Flexcache 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 delete_collection (*args, records: Iterable[_ForwardRef('Flexcache')] = None, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Optional[int] = None, poll_timeout: Optional[int] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse
-
Deletes a FlexCache. If a FlexCache volume is online, it is offlined before deletion.

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

Send the difference in the object's state to the host as a modification request.
Calculates the difference in the object's state since the last time we interacted with the host and sends this in the request body.
Args
hydrate
- If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of the object.
poll
- If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval
- If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout
- If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
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 normally be sent as query parameters to the host. If any of these pairs are parameters that are sent as formdata then only parameters of that type will be accepted and all others will be discarded.
Returns
A
NetAppResponse
object containing the details of the HTTP response.Raises
NetAppRestError
: If the API call returned a status code >= 400 def post (self, hydrate: bool = False, poll: bool = True, poll_interval: Optional[int] = None, poll_timeout: Optional[int] = None, **kwargs) -> NetAppResponse

Default property values
If not specified in POST, the following default property values are assigned: *
size
- 10% of origin volume size or 1GB per constituent, whichever is greater. *guarantee.type

- false if aggr-list is not used. This property is only used when auto-provisioning a FlexCache volume. *is_disconnected_mode_off_for_locks
- false. This property specifies if the origin will honor the cache side locks when doing the lock checks in the disconnected mode. *dr_cache
- false if FlexCache is not a DR cache. This property is used to create a DR FlexCache. *global_file_locking_enabled
- false. This property specifies whether global file locking is enabled on the FlexCache volume. *writeback.enabled
- false. This property specifies whether writeback is enabled for the FlexCache volume. *relative_size.enabled
- false. This property specifies whether the relative sizing is enabled for the FlexCache volume. *relative_size.percentage
- 10. This property specifies the percent size FlexCache volume should have relative to the total size of the origin volume.Related ONTAP commands
