Update the SnapMirror policy

PATCH /snapmirror/policies/{uuid}

Updates the SnapMirror policy.

Important notes

  • The properties "transfer_schedule" and "throttle" can be modified only if all the SnapMirror relationships associated with the specified SnapMirror policy have the same values.

  • The properties "retention.label" and "retention.count" are mandatory if "retention" is provided in the input. The provided "retention.label" is the final list and is replaced with the existing values.

  • The value of the "identity_preservation" property cannot be changed if the SnapMirror relationships associated with the policy have different identity_preservation configurations.

  • If the SnapMirror policy "identity_preservation" value matches the "identity_preservation" value of the associated SnapMirror relationships, then the "identity_preservation" value can be changed from a higher "identity_preservation" threshold value to a lower "identity_preservation" threshold value but not vice-versa. For example, the threshold value of the "identity_preservation" property can be changed from "full" to "exclude_network_config" to "exclude_network_and_protocol_config", but could not be increased from "exclude_network_and_protocol_config" to "exclude_network_config" to "full".

Example

Updating the "retention" property

 PATCH "/api/snapmirror/policies/fe65686d-00dc-11e9-b5fb-0050568e3f83" '{"retention" : {"label" : ["sm_created", "lab2"], "count": ["1","2"], "creation_schedule": {"name": ["weekly"]}}}'

Updating "transfer_schedule", "throttle", and "identity_preservation" properties

 PATCH "/api/snapmirror/policies/8aef950b-3bef-11e9-80ac-0050568ea591" '{"transfer_schedule.name" : "weekly", "throttle" : "100", "identity_preservation":"exclude_network_and_protocol_config"}'

Parameters

Name Type In Required Description

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds. This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job. If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.
