StartInstances

1. API Description

This API is used to start one or more virtual machine instances.

Note

• You can only perform this operation on instances whose status is STOPPED and that are not in the recycle bin.

• If the API is called successfully, the instance status will become BOOTING. After the instance is started, its status will become RUNNING.

• This API is an async API. A response is returned after the request is sent. However, it does not mean the start has been completed. You can use DescribeInstancesStatus to query the status of the instance. If the status changes from BOOTING to RUNNING, it means that the instance has been started successfully. Any operations on the instances are not allowed while creating.

• Batch operations are supported. The maximum number of instances in each request is 100.

2. Input Parameters

The following request parameter list only provides API request parameters.

Parameter Name	Required	Type	Description
instanceIds	Yes	Array of String	Instance ID(s). To obtain the instance IDs, you can call DescribeInstancesStatus and look for instanceId in the response. The maximum number of instances in each request is 100.

3. Output Parameters

Parameter Name	Type	Description
requestId	String	The unique request ID, which is returned for each request. RequestId is required for locating a problem.
