If OperationLocks in the response contains "LockReason" : "security" for an instance when you query the information of the instance, the instance is locked for security reasons and cannot be started.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters


Parameter	Type	Required	Example	Description
Action	String	Yes	StartInstance	The operation that you want to perform. Set the value to StartInstance.
InstanceId	String	Yes	i-bp67acfmxazb4p****	The ID of the instance that you want to start.
InitLocalDisk	Boolean	No	true	Specifies whether to restore the instance to its initial health state. This parameter is applicable to instances that are equipped with local disks, such as d1, i1, and i2 instances. If a local disk of a d1, i1, or i2 instance fails, you can use this parameter to specify whether to restore the instance to its initial health state on startup. Valid values: true: restores the instance to its initial health state on startup. After the instance is restored to its initial health state, data stored on the local disks of the instance is lost. false: does not perform operations and keeps the instance in the current state.
