If the pay-as-you-go or subscription billing method of a cloud disk does not meet your business requirements, you can perform the operations described in this topic to change the billing method of the disk.
Prerequisites
The disk whose billing method you want to change is a cloud disk. You cannot separately change the billing method of an elastic ephemeral disk or a local disk. You can change the billing method of an elastic ephemeral disk or a local disk only when you change the billing method of the Elastic Compute Service (ECS) instance to which the disk is attached. For more information, see Change the billing method of an instance from subscription to pay-as-you-go and Change the billing method of an instance from pay-as-you-go to subscription.
The billing method used by the cloud disk is subscription or pay-as-you-go. You cannot change the billing method of a cloud disk if the disk is attached to a preemptible instance or the bills of the disk are offset by a cost-saving plan such as a savings plan or a storage capacity unit (SCU).
The ECS instance to which the cloud disk is attached is in the Running or Stopped state.
The cloud disk meets the following requirements:
The cloud disk is in the In Use (In_use) state.
The multi-attach feature is disabled for the cloud disk. You cannot change the billing method of cloud disks for which the multi-attach feature is enabled. For more information, see Multi-attach for cloud disks.
The billing method of the cloud disk is not changed within the previous 5 minutes.
Procedure
You cannot separately change the billing method of a system disk. To change the billing method of a system disk, change the billing method of the ECS instance to which the disk is attached. For more information, see Change the billing method of an instance from subscription to pay-as-you-go and Change the billing method of an instance from pay-as-you-go to subscription.
You can refer to different topics to change the billing method of a data disk based on your business requirements.
