Changes the disk category of a cloud disk or the performance level of an Enterprise SSD (ESSD). You cannot change the disk categories of Regional ESSDs (in public preview), basic disks, elastic ephemeral disks, and local disks.
Operation description
To minimize impacts on your business, change the disk categories or performance levels of cloud disks during off-peak hours.
Take note of the following items:
-
To change the performance level of an ESSD, take note of the following items:
- If the ESSD is a subscription ESSD, you can only upgrade its performance level.
- If the ESSD is a pay-as-you-go ESSD, you can upgrade or downgrade its performance level. However, you cannot downgrade the performance level to PL0.
- The ESSD must be in the In Use (In_Use) or Unattached (Available) state.
- If the ESSD is attached to an Elastic Compute Service (ECS) instance, the instance must be in the Running (Running) or Stopped (Stopped) state. The instance cannot be in the Expired state or stopped due to an overdue payment.
- If you cannot upgrade the performance level of an ESSD due to the capacity limit, extend the ESSD by calling the ResizeDisk operation and then try again. For more information, see ESSDs .
-
For information about the limits on changing the disk category of a cloud disk, see Change the category of a disk.
-
For the disk categories to which cloud disks of each disk category can be changed, see Change the category of a disk.
After the disk category of a cloud disk is changed, the billing of the cloud disk has the following changes:
- If the cloud disk is a pay-as-you-go disk, you are charged for the disk based on the new disk category.
- If the cloud disk is a subscription disk, you may be charged additionally based on the price difference between the old and new disk categories and the remaining days of the billing cycle, starting from 00:00 the next day until the end of the subscription period.
For information about the billing of cloud disks, see Block storage devices.

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 Resourcesis 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.
| Operation | Access level | Resource type | Condition key | Associated operation |
|---|---|---|---|---|
| ecs:ModifyDiskSpec | update | *Disk acs:ecs:{#regionId}:{#accountId}:disk/{#diskId} |
| none |
Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| DiskId | string | Yes | The disk ID. | d-bp131n0q38u3a4zi**** |
| PerformanceLevel | string | No | The new performance level of the ESSD. Valid values:
Default value: PL1. | PL2 |
| DiskCategory | string | No | The new disk category of the cloud disk. Valid values:
This parameter is empty by default, which indicates that the disk category is not changed. Note
| cloud_essd |
| DryRun | boolean | No | Specifies whether to perform only a dry run, without performing the actual request. Valid values:
Default value: false. | false |
| ProvisionedIops | long | No | The provisioned read/write IOPS of the ESSD AutoPL disk. Valid values: 0 to min{50,000, 1,000 × Capacity - Baseline IOPS}. Baseline IOPS = min{1,800 + 50 × Capacity, 50,000}. Note
This parameter is available only if you set DiskCategory to cloud_auto. For more information, see ESSD AutoPL disks and Modify the performance configurations of an ESSD AutoPL disk.
| 50000 |
| PerformanceControlOptions | object | No | The disk performance specifications. | |
| IOPS | integer | No | The new IOPS rate of the cloud disk. You can modify the IOPS rate of only cloud disks in dedicated block storage clusters. Valid values: 900 to maximum IOPS per cloud disk (with an increment of 100). For more information, see Block storage performance. | 2000 |
| Throughput | integer | No | The new throughput of the cloud disk. You can change the throughput of only cloud disks in dedicated block storage clusters. Unit: MB/s. Valid values: 60 to maximum throughput per disk. For more information, see Block storage performance. | 200 |
| Recover | string | No | Specifies whether to reset the IOPS rate and throughput of the cloud disk. This parameter takes effect only when the cloud disk belongs to a dedicated block storage cluster. After you specify this parameter, PerformanceControlOptions.IOPS and PerformanceControlOptions.Throughput do not take effect. Set the value to All, which indicates that the IOPS rate and throughput of the cloud disk are reset to the initial values. | All |
