Module netapp_ontap.resources.metrocluster_dr_group

Copyright © 2022 NetApp Inc. All rights reserved.

Overview

You can use this API to create, perform operations, and retrieve relevant information pertaining to MetroCluster DR groups. The GET operation retrieves all the DR groups in the MetroCluster over IP configuration or a DR group information specified by the DR group id. The POST request can be used to create a new DR group in the MetroCluster over IP configuration. The DELETE operation removes a DR group information specified by the DR group id from the existing MetroCluster over IP configuration.

Creating a new DR group

A new DR group in MetroCluster over IP configuration is created by issuing a POST to /cluster/metrocluster/dr-groups. Parameters are provided in the body of the POST request. This operation requires a valid MetroCluster over IP configuration. The new nodes added belong to either the local or partner cluster.

Fields used for setting up a new DR group

The fields used for MetroCluster APIs are either required or optional and are described as follows:

Required configuration fields

These fields are always required for any POST /cluster/dr-groups request.

  • partner_cluster.name - Specifies the partner cluster name to which cluster peering has been established.
  • dr_pairs - Specifies local and DR partner node pairs. Each pair uniquely identifies a DR group.

Optional configuration fields

This field is used to set up additional MetroCluster DR configuration.

  • vlans - Specifies VLAN IDs and port combinations for MetroCluster platforms supporting custom VLAN IDs.

Polling the create job

After a successful POST /cluster/metrocluster/dr-groups is issued, an HTTP status code of 202 (Accepted) is returned along with a job UUID and a link in the body of the response. The create job continues asynchronously and can be monitored by using the job UUID and the /cluster/jobs API. The "message" field in the response of the GET /cluster/jobs/{uuid} request shows the current step in the job, and the "state" field shows the overall state of the job.

Deleting a DR group using ID

A DR group in MetroCluster over IP configuration can be deleted by issuing a DELETE to /cluster/metrocluster/dr-groups/{id}. No parameters are required for the DELETE request. The following preparation steps must be completed on the local and partner clusters before removing a DR group.

  • Move all the data volumes to another DR group.
  • Move all the MDV_CRS metadata volumes to another DR group.
  • Delete all the MDV_aud metadata volumes that may exist in the DR group to be removed.
  • Delete all the data aggregates in the DR group to be removed. Root aggregates are not deleted.
  • Migrate all the data LIFs to home nodes in another DR group.
  • Migrate the cluster management LIF to a home node in another DR group. Node management and inter-cluster LIFs are not migrated.
  • Transfer epsilon to a node in another DR group. The operation is refused if the preparation steps are not completed on the local and partner clusters.

Polling the delete job

After a successful DELETE /cluster/metrocluster/dr-groups is issued, an HTTP status code of 202 (Accepted) is returned along with a job UUID and a link in the body of the response. The delete job continues asynchronously and can be monitored by using the job UUID and the /cluster/jobs API. The "message" field in the response of the GET /cluster/jobs/{uuid} request shows the current step in the job, and the "state" field shows the overall state of the job.

Classes

class MetroclusterDrGroup (*args, **kwargs)

DR group 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

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, records: Iterable[_ForwardRef('MetroclusterDrGroup')] = None, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Remove the DR group from the current MetroCluster over IP configuration specified by the DR group id.

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.
records
Can be provided in place of a query. If so, this list of objects will be deleted from the host.
body
The body of the delete request. This could be a Resource instance or a dictionary 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 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 all the DR group in the MetroCluster over IP configuration.

Learn more


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 all the DR group in the MetroCluster over IP configuration.

Learn more


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.

def post_collection(records: Iterable[_ForwardRef('MetroclusterDrGroup')], *args, hydrate: bool = False, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> Union[List[MetroclusterDrGroup], NetAppResponse]

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.

Returns

A list of Resource objects matching the provided
type which have been created by the host and returned. This is _not_
 
the same list that was provided, so to continue using the object, you
 

should save this list. If poll is set to False, then a NetAppResponse object is returned instead.

Raises
