Request parameters
Parameter | Type | Required | Example | Description |
---|---|---|---|---|
Action | String | Yes | DetachLoadBalancers |
The operation that you want to perform. Set the value to DetachLoadBalancers. |
ScalingGroupId | String | Yes | asg-bp1ffogfdauy0jw0**** |
The ID of the scaling group. |
ForceDetach | Boolean | No | false |
Specifies whether to remove Elastic Compute Service (ECS) instances in the scaling group from the backend server groups of the SLB instance. Valid values:
Default value: false. |
ClientToken | String | No | 123e4567-e89b-12d3-a456-42665544**** |
The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length. For more information, see How to ensure idempotence. |
Async | Boolean | No | false |
Specifies whether to perform asynchronous calls when you disassociates an SLB instance from the scaling group. Asynchronous calls ensure the transactional nature of operations. This means that the execution results take effect only if all operations are successfully performed. We recommend that you perform asynchronous calls. Valid values:
Default value: false. |
RegionId | String | No | cn-qingdao |
The ID of the region where the scaling group resides. |
LoadBalancer.N | String | Yes | lb-2zeur05gfs**** |
The ID of SLB instance N. You can disassociate up to five SLB instances from a scaling group at a time. |
Response parameters
Parameter | Type | Example | Description |
---|---|---|---|
ScalingActivityId | String | asa-bp140qd7mak8k63f**** |
The ID of the scaling activity. A value of this parameter is returned only when Async is set to true. You can call the DescribeScalingActivities operation to query the returned IDs of the scaling activities and view the execution status of the scaling activities. |
RequestId | String | 473469C7-AA6F-4DC5-B3DB-A3DC0DE3**** |
The ID of the request. |
