DescribeDisasterRecoverGroups
POST
Query the information on spread placement groups.
Wire call
Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /cvm/DescribeDisasterRecoverGroups path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

Response
Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.
| Field | Type | Description |
|---|---|---|
| DisasterRecoverGroupSet | DisasterRecoverGroup[] | Information on spread placement groups. |
| TotalCount | integer | Total number of placement groups of the user. |
| RequestId | string | The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem. |
