StartShiftLoadBalancerZones - Server Load Balancer - Alibaba Cloud Documentation Center

Removes an elastic IP address (EIP) or a virtual IP address (VIP) of a zone from a DNS record.

This operation is supported by Application Load Balancer (ALB) instances that use static IP addresses. The zone cannot be removed if the ALB instance has only one available zone.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	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 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.	5A2CFF0E-5718-45B5-9D4D-70B3FF3898
DryRun	boolean	No	Specifies whether to perform only 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.	true
LoadBalancerId	string	Yes	The ALB instance ID.	alb-o9ulmq5hgn68jk****
ZoneMappings	array<object>	Yes	The mappings between zones and vSwitches. Note You can remove only one zone in each call.
	object	No
VSwitchId	string	Yes	The ID of the vSwitch in the zone. By default, each zone uses one vSwitch and one subnet.	vsw-bp1rmcrwg3erh1fh8****
ZoneId	string	Yes	The zone ID. You can call the DescribeZones operation to query the most recent zone list.	cn-hangzhou-a
