Module `netapp_ontap.resources.snapmirror_relationship`

Overview

This API manages asynchronous extended data protection (XDP) relationships for FlexVols, FlexGroups, or SVMs. It is also used to manage a synchronous relationship between FlexVol volumes, which provides zero RPO data protection and active synchronous relationship with automated failover between Consistency Group endpoints which provides zero RTO data protection. To create an asynchronous extended data protection relationship with FlexVol volumes, FlexGroup volumes, or SVMs, use the policy of type "async". To create a synchronous relationship between FlexVol volumes, use the policy of type "sync" with sync_type of either "sync" or "strict_sync". To create an active synchronous relationship with automated failover between Consistency Group endpoints, use the policy of type "sync" with sync_type "automated_failover". You can create an asynchronous extended data protection relationship between the source and destination which can be used by the transfer APIs to perform SnapMirror "restore" operations.
To create FlexVol or FlexGroup SnapMirror relationships, the source volume must be in the "online" state and be a read_write type; the destination volume must be in the "online" state and be a data protection type. In the case of a SnapMirror relationship for a Consistency Group of FlexVol volumes, note that the SnapMirror creation will result in the creation of Consistency Group on the source cluster if it did not already exist with the exact same name and set of FlexVol volumes specified in the current operation. Additionally, if the specified Consistency Group was already present and was already a part of an existing SnapMirror relationship, the process will fail. On the other hand, the creation of Consistency Group on destination cluster is a part of SnapMirror creation workflow itself. To create SnapMirror relationships between SVMs, the source SVM must be of subtype "default" and the destination SVM of subtype "dp_destination". Additionally, SVMs must be peered before a relationship can be established between them when the "create_destination" property is not specified. When the "create_destination" property is specified then the destination SVM is provisioned on the destination cluster and the SVM peer relationship is established between the source SVM and the new destination SVM provided the source SVM has the SVM peering permission for the destination cluster. DP FlexVol SnapMirror relationships cannot be created using this API but existing relationships can be listed or managed. The SnapMirror functionality is subdivided into relationship APIs and transfer APIs: - SnapMirror relationship APIs are used to create and manage the SnapMirror relationships. - SnapMirror transfer APIs are used to manage data transfers.

Classes

class SnapmirrorRelationship (*args, **kwargs)

SnapMirror relationship information. The SnapMirror relatiosnhip can be either "async" or "sync" based on the type of SnapMirror policy associated with the relationship. The source and destination endpoints of a SnapMirror relationship must be of the same type, for example, if the source endpoint is a FlexVol volume then the destination endpoint must be a FlexVol volume.
The SnapMirror policy type "async" can be used when the SnapMirror relationship has FlexVol volume or FlexGroup volume or SVM as the endpoint. The SnapMirror policy type "sync" can be used when the SnapMirror relationship has FlexVol volume as the endpoint. The SnapMirror policy type "sync" with "sync_type" as "automated_failover" can be used when the SnapMirror relationship has Consistency Group as the endpoint.

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.

Resource

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('SnapmirrorRelationship')] = 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

Deletes a SnapMirror relationship.

Important notes

The "destination_only", "source_only", and "source_info_only" flags are mutually exclusive. If no flag is specified, the relationship is deleted from both the source and destination and all common Snapshot copies between the source and destination are also deleted.
For a restore relationship, the call must be executed on the cluster containing the destination endpoint without specifying the destination_only, source_only, or source_info_only parameters.
Additionally, ensure that there are no ongoing transfers on a restore relationship before calling this API.
The "failover", "force-failover" and "failback" query parameters are only applicable for SVM-DR SnapMirror relationships.
When a SnapMirror relationship associated with a pair of source and destination Consistency Groups is deleted, the corresponding Consistency Groups on the source and destination clusters are not automatically deleted and remain in place.

DOC /snapmirror/relationships

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

Updates a SnapMirror relationship. This API is used to initiate SnapMirror operations such as "initialize", "resync", "break", "quiesce", and "resume" by specifying the appropriate value for the "state" field. It is also used to modify the SnapMirror policy associated with the specified relationship. Additionally, a SnapMirror relationship can be failed over to the destination endpoint or a failed over SnapMirror relationship can be failed back to the original state or a SnapMirror relationship direction can be reversed using this API.
To initialize the relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync".
To break the relationship or to failover to the destination endpoint and start serving data from the destination endpoint, PATCH the state to "broken_off" for relationships with a policy of type "async" or "sync". SnapMirror relationships with the policy type as "sync" and sync_type as "automated_failover" cannot be "broken_off".
To resync the broken relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync".
To failback the failed over relationship and start serving data from the source endpoint, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync" and set the query flag "failback" as "true". SnapMirror relationships with the policy type as "sync" and sync_type as "automated_failover" can be in "broken_off" state due to a failed attempt of automated SnapMirror failover operation.
To pause the relationship, suspending further transfers, PATCH the state to "paused" for relationships with a policy of type "async" or "sync". SnapMirror relationships with the policy type as "sync" and sync_type as "automated_failover" cannot be "paused".
To resume transfers for a paused relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync".
To reverse the direction of the relationship, PATCH the "source.path" with the destination endpoint and the "destination.path" with the source endpoint and the relationship state to "snapmirrored" for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync".
The values "in_sync", "out_of_sync", and "synchronizing" are only applicable to relationships with a policy of type "sync".

Examples

The following examples show how to perform the SnapMirror "resync", "initialize", "resume", "quiesce", and "break" operations. In addition, a relationship can be failed over to the destination endpoint and start serving data from the destination endpoint. A failed over relationship can be failed back to the source endpoint and serve data from the source endpoint. Also a relationship can be reversed by making the source endpoint as the new destination endpoint and the destination endpoint as the new source endpoint.

def post_collection(records: Iterable[_ForwardRef('SnapmirrorRelationship')], *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[SnapmirrorRelationship], NetAppResponse]

Creates a SnapMirror relationship. This API can optionally provision the destination endpoint when it does not exist. This API must be executed on the cluster containing the destination endpoint unless the destination endpoint is being provisioned. When the destination endpoint is being provisioned, this API can also be executed from the cluster containing the source endpoint. Provisioning of the destination endpoint from the source cluster is supported for the FlexVol volume, FlexGroup volume and Consistency Group endpoints. For SVM endpoint, provisioning of the destination SVM endpoint is not supported from the source cluster.
When the destination endpoint exists the source SVM and the destination SVM must be in an SVM peer relationship. When provisioning the destination endpoint, the SVM peer relationship between the source SVM and the destination SVM is established as part of the destination, provision provided the source SVM has SVM peering permission for the destination cluster.

Required properties

source.path - Path to the source endpoint of the SnapMirror relationship.
destination.path - Path to the destination endpoint of the SnapMirror relationship.
destination.consistency_group_volumes - List of FlexVol volumes of type "RW" that are constituents of a Consistency Group.
destination.consistency_group_volumes - List of FlexVol volumes of type "DP" that are constituents of a Consistency Group.

Recommended optional properties

policy.name or policy.uuid - Policy governing the SnapMirror relationship.
state - Set the state to "snapmirrored" to automatically initialize the relationship.
create_destination.enabled - Enable this property to provision the destination endpoint.

Default property values

If not specified in POST, the following default property values are assigned: * policy.name - Asynchronous * restore - false * create_destination.tiering.policy - _snapshot_only_ (when create_destination.tiering.supported is true for FlexVol volume) * create_destination.tiering.policy - _none_ (when create_destination.tiering.supported is true for FlexGroup volume) * create_destination.storage_service.enforce_performance - _false_ * source.ipspace - _Default_ * destination.ipspace - _Default_

Send this collection of objects to the host as a creation request.

Args

records: A list of Resource objects to send to the server to be created.
*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 create a bar for a particular foo, the foo.name value should be passed.
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 each object. When hydrate is set to True, poll must also be set to True.
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 patched.

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

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

Methods

def delete(self, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, **kwargs) -> NetAppResponse

Deletes a SnapMirror relationship.

Important notes

The "destination_only", "source_only", and "source_info_only" flags are mutually exclusive. If no flag is specified, the relationship is deleted from both the source and destination and all common Snapshot copies between the source and destination are also deleted.
For a restore relationship, the call must be executed on the cluster containing the destination endpoint without specifying the destination_only, source_only, or source_info_only parameters.
Additionally, ensure that there are no ongoing transfers on a restore relationship before calling this API.
The "failover", "force-failover" and "failback" query parameters are only applicable for SVM-DR SnapMirror relationships.
When a SnapMirror relationship associated with a pair of source and destination Consistency Groups is deleted, the corresponding Consistency Groups on the source and destination clusters are not automatically deleted and remain in place.

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.
**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

Class variables

consistency_group_failover GET

The consistency_group_failover field of the snapmirror_relationship.

create_destination POST

The create_destination field of the snapmirror_relationship.

destination GET POST PATCH

This property is the destination endpoint of the relationship. The destination endpoint can be a FlexVol volume, FlexGroup volume, Consistency Group, or SVM. For the POST request, the destination endpoint must be of type "DP" when the endpoint is a FlexVol volume or a FlexGroup volume. When specifying a Consistency Group as the destination endpoint, the "destination.consistency_group_volumes" property must be specified with the FlexVol volumes of type "DP". The POST request for SVM must have a destination endpoint of type "dp-destination". The destination endpoint path name must be specified in the "destination.path" property. For relationships of type "async", the destination endpoint for FlexVol volume and FlexGroup volume will change to type "RW" when the relationship status is "broken_off" and will revert to type "DP" when the relationship status is "snapmirrored" or "in_sync" using the PATCH request. The destination endpoint for SVM will change from "dp-destination" to type "default" when the relationship status is "broken_off" and will revert to type "dp-destination" when the relationship status is "snapmirrored" using the PATCH request. When the destination endpoint is a Consistency Group, the Consistency Group FlexVol volumes will change to type "RW" when the relationship status is "broken_off" and will revert to type "DP" when the relationship status is "in_sync" using the PATCH request.

exported_snapshot GET

Snapshot copy exported to clients on destination.

healthy GET

Is the relationship healthy?

lag_time GET

Time since the exported Snapshot copy was created.

Example: PT8H35M42S

links GET

The links field of the snapmirror_relationship.

policy GET POST PATCH

The policy field of the snapmirror_relationship.

preserve PATCH

Set to true on resync to preserve Snapshot copies on the destination that are newer than the latest common Snapshot copy. This property is applicable only for relationships with FlexVol volume or FlexGroup volume endpoints and when the PATCH state is being changed to "snapmirrored".

quick_resync PATCH

Set to true to reduce resync time by not preserving storage efficiency. This property is applicable only for relationships with FlexVol volume endpoints and when the PATCH state is being changed to "snapmirrored".

recover_after_break PATCH

Set to true to recover from a failed SnapMirror break operation on a FlexGroup volume relationship. This restores all destination FlexGroup constituent volumes to the latest Snapshot copy, and any writes to the read-write constituents are lost. This property is applicable only for SnapMirror relationships with FlexGroup volume endpoints and when the PATCH state is being changed to "broken_off".

restore GET POST

Set to true to create a relationship for restore. To trigger restore-transfer, use transfers POST on the restore relationship. SnapMirror relationships with the policy type "async" can be restored. SnapMirror relationships with the policy type "sync" cannot be restored.

restore_to_snapshot PATCH

Specifies the Snapshot copy to restore to on the destination during the break operation. This property is applicable only for SnapMirror relationships with FlexVol volume endpoints and when the PATCH state is being changed to "broken_off".

source GET POST PATCH

This property is the source endpoint of the relationship. The source endpoint can be a FlexVol volume, FlexGroup volume, Consistency Group, or SVM. To establish a SnapMirror relationship with SVM as source endpoint, the SVM must have only FlexVol volumes. For a Consistency Group this property identifies the source Consistency Group name. When specifying a Consistency Group as the source endpoint, the "source.consistency_group_volumes" property must be specified with the FlexVol volumes of type "RW". FlexVol volumes of type "DP" cannot be specified in the "source.consistency_group_volumes" list.

state GET POST PATCH

State of the relationship.
To initialize the relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or to state "in_sync" for relationships with a policy of type "sync".
To break the relationship, PATCH the state to "broken_off" for relationships with a policy of type "async" or "sync". SnapMirror relationships with the policy type as "sync" and "sync_type" as "automated_failover" cannot be "broken_off".
To resync the relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or to state "in_sync" for relationships with a policy of type "sync". SnapMirror relationships with the policy type as "sync" and "sync_type" as "automated_failover" can be in "broken_off" state due to a failed attempt of SnapMirror failover.
To pause the relationship, suspending further transfers, PATCH the state to "paused" for relationships with a policy of type "async" or "sync". SnapMirror relationships with the policy type as "sync" and "sync_type" as "automated_failover" cannot be "paused".
To resume transfers for a paused relationship, PATCH the state to "snapmirrored" for relationships with a policy of type "async" or to state "in_sync" for relationships with a policy of type "sync".
The entries "in_sync", "out_of_sync", and "synchronizing" are only applicable to relationships with a policy of type "sync". A PATCH call on the state change only triggers the transition to the specified state. You must poll on the "state", "healthy" and "unhealthy_reason" properties using a GET request to determine if the transition is successful. To automatically initialize the relationship when specifying "create_destination" property, set the state to "snapmirrored" for relationships with a policy of type "async" or to state "in_sync" for relationships with a policy of type "sync".

Valid choices:

broken_off
paused
snapmirrored
uninitialized
in_sync
out_of_sync
synchronizing

transfer GET POST PATCH

The transfer field of the snapmirror_relationship.

unhealthy_reason GET

Reason the relationship is not healthy. It is a concatenation of up to four levels of error messages.

Example: [{"code":"6621444","message":"Failed to complete update operation on one or more item relationships.","parameters":[]},{"code":"6621445","message":"Group Update failed","parameters":[]}]

uuid GET

The uuid field of the snapmirror_relationship.

Example: 4ea7a442-86d1-11e0-ae1c-123478563412
