You can call this operation to modify the performance level of an enhanced SSD (ESSD).

Description

To modify the performance level of an enhanced SSD, note the following content:

  • You can only upgrade the performance level of a subscription enhanced SSD. However, you can upgrade or downgrade the performance level of a pay-as-you-go enhanced SSD.
  • The enhanced SSD must be in the In Use or Unattached state.
  • If the enhanced SSD is attached to an ECS instance, the instance must be in the Running or Stopped state. The instance cannot be expired or stopped due to an overdue payment.
  • The new performance level of the enhanced SSD takes effect immediately after you call this operation. The enhanced SSD is then billed based on the unit price specific to the new performance level.
  • If you cannot upgrade the performance level of the enhanced SSD due to its capacity limit, resize the enhanced SSD by calling the ResizeDisk operation and then try again. For more information, see Enhanced SSD (ESSD).

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.

Error codes

HTTP status code Error code Error message Description
404 InvalidDiskId.NotFound The specified disk does not exist. The error message returned because the specified disk ID does not exist. Check whether the disk ID is correct.
403 DiskInArrears The specified operation is denied as your disk owing fee. The error message returned because the specified disk has an overdue payment.
404 InvalidInstanceId.NotFound The specified InstanceId does not exist. The error message returned because the specified instance ID does not exist. Check whether the instance ID is correct.
403 InstanceExpiredOrInArrears The specified operation is denied as your prepay instance is expired (prepay mode) or in arrears (afterpay mode). The error message returned because the subscription instance has expired. Renew the instance first.
403 IncorrectDiskStatus The current disk status does not support this operation. The error message returned because the operation is not supported while the disk is in the current state. Ensure that the disk is available and has no overdue payments.

403 OperationDenied The type of the disk does not support the operation. The error message returned because the disk category does not support the specified operation.
400 InvalidPerformanceLevel.Malformed The specified parameter PerformanceLevel is not valid. The error message returned because the specified PerformanceLevel parameter is invalid.
403 OperationDenied.PerformanceLevelNotMatch The specified PerformanceLevel and disk size do not match. The error message returned because the specified performance level and the disk size do not correspond to each other.
