snapmirror_destination_creation

Use this object to provision the destination endpoint when establishing a SnapMirror relationship for a FlexVol volume, FlexGroup volume, or SVM. Given a source endpoint, the destination endpoint is provisioned in the SVM specified in the "destination.path" property. The SVM destination endpoint can only be provisioned on the local cluster. To provision the SVM destination endpoint use the optional "source.cluster.name" property to specify the remote cluster name or use the optional "source.cluster.uuid" property to specify the remote cluster UUID. When "create_destination.enabled" option is specified while making a POST for a SnapMirror relationship, the relationship can be automatically initialized by setting the "state" either to "snapmirrored" when the policy is of type "async" or to "in_sync" when the policy is of type "sync". The "destination.path" property must specify the destination endpoint path. For example, for FlexVol volume and FlexGroup volume, the "destination.path" can be specified as , and for SVM data protection, the "destination.path" must be specified as <destination-SVM-name:>. For a FlexVol volume or FlexGroup volume destination endpoint, the properties in this object can be specified either from the source or destination cluster. For an SVM destination endpoint, the properties in this object can be specified from the destination cluster. This object is not supported for non ONTAP endpoints.

  • x-ntap-createOnly: true

destination

snapmirror_endpoint

Endpoint of a SnapMirror relationship. For a GET request, the property "cluster" is populated when the endpoint is on a remote cluster. A POST request to create the destination SVM endpoint or to establish an SVM DR relationship must have the property "cluster" populated with the remote cluster details. A POST request to create the destination FlexVol volume or FlexGroup volume endpoints can optionally specify the "cluster" property. A POST request to establish a SnapMirror relationship when the source SVM and the destination SVM are not peered, must specify the "cluster" property.

exported_snapshot

string

Snapshot copy exported to clients on destination.

healthy

boolean

Is the relationship healthy?

lag_time

string

Time since the exported Snapshot copy was created.

policy

policy

Basic policy information of the relationship.

preserve

boolean

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 FlexGroup or FlexVol endpoints and when the PATCH state is being changed to "snapmirrored".

quick_resync

boolean

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

recover_after_break

boolean

Set to true to recover from a failed SnapMirror break operation on a FlexGroup relationship. This restores all destination FlexGroup constituents 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 endpoints and when the PATCH state is being changed to "broken_off".

restore

boolean

Set to true to create a relationship for restore. To trigger restore-transfer, use transfers POST on the restore relationship.

restore_to_snapshot

string

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

source

snapmirror_endpoint

Endpoint of a SnapMirror relationship. For a GET request, the property "cluster" is populated when the endpoint is on a remote cluster. A POST request to create the destination SVM endpoint or to establish an SVM DR relationship must have the property "cluster" populated with the remote cluster details. A POST request to create the destination FlexVol volume or FlexGroup volume endpoints can optionally specify the "cluster" property. A POST request to establish a SnapMirror relationship when the source SVM and the destination SVM are not peered, must specify the "cluster" property.

state

string

State of the relationship. 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, PATCH the state to "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 pause the relationship, suspending further transfers, PATCH the state to "paused". To resume transfers for a paused relationship, PATCH the state to "snapmirrored" or "in_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”, set the state to “snapmirrored” for relationships with a policy of type "async" or "in_sync" for relationships with a policy of type "sync".

transfer

transfer

Basic information on the current transfer.

unhealthy_reason

array[snapmirror_error]

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

storage_service

Name Type Description

enabled

boolean

This property indicates whether to create the destination endpoint using storage service.

enforce_performance

boolean

Optional property to enforce storage service performance on the destination endpoint when the destination endpoint is used for read-write operations. This property is applicable to FlexVol volume and FlexGroup volume endpoints.

name

string

Optional property to specify the storage service name for the destination endpoint. This property is considered when the property "create_destination.storage_service.enabled" is set to "true". When the property "create_destination.storage_service.enabled" is set to "true" and the "create_destination.storage_service.name" for the endpoint is not specified, then ONTAP selects the highest storage service available on the cluster to provision the destination endpoint. This property is applicable to FlexVol volume and FlexGroup volume endpoints.

  • enum: ["extreme", "performance", "value"]

tiering

Name Type Description

policy

string

Optional property to specify the destination endpoint's tiering policy when "create_destination.tiering.supported" is set to "true". This property is applicable to FlexVol volume and FlexGroup volume endpoints. This property determines whether the user data blocks of the destination endpoint in a FabricPool will be tiered to the cloud store when they become cold. FabricPool combines flash (performance tier) with a cloud store into a single aggregate. Temperature of the destination endpoint volume blocks increases if they are accessed frequently and decreases when they are not. all ‐ This policy allows tiering of both destination endpoint Snapshot copies and the user transfered data blocks to the cloud store as soon as possible by ignoring the temperature on the volume blocks. This tiering policy is not applicable for synchronous relationships. auto ‐ This policy allows tiering of both destination endpoint Snapshot copies and the active file system user data to the cloud store none ‐ Destination endpoint volume blocks will not be tiered to the cloud store. snapshot_only ‐ This policy allows tiering of only the destination endpoint volume Snapshot copies not associated with the active file system. The default tiering policy is "snapshot_only" for a FlexVol volume and "none" for a FlexGroup volume.

supported

boolean

Optional property to enable provisioning of the destination endpoint volumes on FabricPool aggregates. This property is applicable to FlexVol volume and FlexGroup volume endpoints. Only FabricPool aggregates are used if this property is set to "true" and only non FabricPool aggregates are used if this property is set to "false". Tiering support for a FlexGroup volume can be changed by moving all of the constituents to the required aggregates. Note that in order to tier data, not only do the destination endpoint volumes need to support tiering by using FabricPools, the "create_destination.tiering.policy" must not be "none". A destination endpoint that uses FabricPools but has a tiering "policy" of "none" supports tiering but will not tier any data.

snapmirror_destination_creation

Use this object to provision the destination endpoint when establishing a SnapMirror relationship for a FlexVol volume, FlexGroup volume, or SVM. Given a source endpoint, the destination endpoint is provisioned in the SVM specified in the "destination.path" property. The SVM destination endpoint can only be provisioned on the local cluster. To provision the SVM destination endpoint use the optional "source.cluster.name" property to specify the remote cluster name or use the optional "source.cluster.uuid" property to specify the remote cluster UUID. When "create_destination.enabled" option is specified while making a POST for a SnapMirror relationship, the relationship can be automatically initialized by setting the "state" either to "snapmirrored" when the policy is of type "async" or to "in_sync" when the policy is of type "sync". The "destination.path" property must specify the destination endpoint path. For example, for FlexVol volume and FlexGroup volume, the "destination.path" can be specified as , and for SVM data protection, the "destination.path" must be specified as <destination-svm-name:>. For a FlexVol volume or FlexGroup volume destination endpoint, the properties in this object can be specified either from the source or destination cluster. For an SVM destination endpoint, the properties in this object can be specified from the destination cluster. This object is not supported for non ONTAP endpoints.</destination-svm-name:>
