Server Load Balancer:UpdateLoadBalancerZones

Last Updated:Nov 11, 2024

Updates the zones of a Gateway Load Balancer (GWLB) instance.

Operation description

Make sure that you fully understand the billing methods and pricing of GWLB before calling this operation.

UpdateLoadBalancerZones is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the GetLoadBalancerAttribute operation to query the status of the GWLB instance.

  • If the GWLB instance is in the Configuring state, the GWLB instance is being modified.
  • If the GWLB instance is in the Active state, the GWLB instance is modified.
Note Before you call this operation, make sure that all zone parameters, including the current zones and the zones that you want to add, are specified. If you do not specify the current zones, the current zones are deleted. You can call the GetLoadBalancerAttribute operation to query the current zones of a GWLB instance.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Request parameters

ParameterTypeRequiredDescriptionExample
LoadBalancerIdstringYes

The GWLB instance ID.

gwlb-9njtjmqt7zfcqm****
ZoneMappingsarray<object>Yes

The mappings between zones and vSwitches. You must specify at least one zone. You can specify at most 20 zones. If the region supports two or more zones, we recommend that you select two or more zones.

ZoneEniModelobjectYes
VSwitchIdstringYes

The ID of the vSwitch in the zone. You can specify only one vSwitch (subnet) in each zone of a GWLB instance.

vsw-bp1n75pbs77v5q6p3****
ZoneIdstringYes

The zone ID. You can call the DescribeZones operation to query the most recent zone list.

cn-hangzhou-h
DryRunbooleanNo

Specifies whether to perform a dry run, without performing the actual request. Valid values:

  • true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error code is returned. If the request passes the dry run, the DryRunOperation error code is returned.
  • false (default): performs a dry run and performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.
false
ClientTokenstringNo

The client token that is used to ensure the idempotence of the request.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters.

Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.
