Virtual Private Cloud:UnassociateHaVip

Last Updated:Jun 18, 2024

Disassociates a high-availability virtual IP address (HAVIP) from an Elastic Compute Service (ECS) instance or an elastic network interface (ENI) in a virtual private cloud (VPC).

Operation description

When you call this operation, take note of the following limits:

  • The ECS instance must be in the Running or Stopped state.

  • The HAVIP must be in the Available or InUse state.

  • UnassociateHaVip is an asynchronous operation. After a request is sent, the system returns a request ID and an instance ID and runs the task in the background. You can call the DescribeHaVips operation to query the status of an HAVIP:

    • If the HAVIP is in the Unassociating state, the HAVIP is being disassociated.
    • If the HAVIP is in the Inuse or Available state, the HAVIP is disassociated.
  • You cannot repeatedly call the UnassociateHaVip operation to disassociate an HAVIP within the specified period of time.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters


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 and cannot exceed 64 characters in length.


The region ID of the HAVIP.

You can call the DescribeRegions operation to query the most recent region list.


The ID of the HAVIP that you want to disassociate.


The ID of the ECS instance or ENI from which you want to disassociate the HAVIP.


Specifies whether to forcefully disassociate the HAVIP from the ECS instance or ENI. Valid values:

  • True
  • False (default)
Note If you set the value to False, you cannot disassociate the HAVIP from the primary instance.

The type of the instance from which you want to disassociate the HAVIP. Valid values:

  • EcsInstance: an ECS instance
  • NetworkInterface: an ENI
Note If you want to disassociate the HAVIP from an ENI, this parameter is required.

Response parameters
