    Elastic Compute Service：ReplaceSystemDisk

    更新時間：Dec 24, 2024

    Replaces the operating system of an Elastic Compute Service (ECS) instance. After you perform an operating system replacement operation, the original disk is released and a new system disk is created. This causes the ID of the system disk to change.

    Operation description

    Usage notes

    Take note of the following items:

    • The category of the system disk cannot be changed.

    • The billing method of the system disk cannot be changed.

    • The instance must be in the Stopped state.

      **

      Note The operation is applicable only to instances of the Virtual Private Cloud (VPC) type. If the instance is a pay-as-you-go instance and economical mode is enabled by default for the instance, you must disable economical mode and enable standard mode when you stop the instance. This prevents the instance from being unable to restart due to insufficient ECS resources after the system disk is replaced. For more information, see StopInstance .

    • The ECS instance cannot be locked for security reasons. If the value of OperationLocks in the DescribeInstances response contains "LockReason": "security" for an instance, the instance is locked for security reasons. For more information, see API behavior when an instance is locked for security reasons.

    • No unpaid orders are associated with the instance.

    • You can configure SystemDisk.Size to specify the capacity of the new system disk.

    After you call the ReplaceSystemDisk operation, you can use one of the following methods to check whether the system disk is replaced:

    • Call the DescribeDisks operation to query the status of the new system disk. If the new system disk is in the In Use state, the system disk is replaced.
    • Call the DescribeInstances operation to query the status of the instance whose system disk is replaced. If the OperationLocks parameter is empty, the system disk is replaced.

    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.

    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:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • 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.
