If the billing method of a disk does not meet your business requirements, you can change the billing method of the disk. The billing methods of data disks attached to subscription Elastic Compute Service (ECS) instances can be changed separately. The billing methods of data disks attached to pay-as-you-go ECS instances and system disks can only be changed together with the billing methods of the instances. This topic describes how to change the billing method of a disk between pay-as-you-go and subscription on an ECS instance.
Prerequisites
The disk is attached to an instance, and the instance is in the Running or Stopped state.
Background information
Usage notes
Alibaba Cloud calculates whether the billing method of your Elastic Compute Service (ECS) instance can be changed based on your usage of the instance. You can perform the operations that are described in this topic to check whether an entry point for changing the billing method of your instance exists in the ECS console. If the entry point does not exist, the billing method of your instance cannot be changed.
You must wait at least 5 minutes between two consecutive billing method changes.
You cannot change the billing method of disks for which the multi-attach feature is enabled. For more information, see Multi-attach for cloud disks.
