RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The ID of the region. You can call the DescribeRegions operation to get the latest list of regions.	cn-hangzhou
DiskId	string	Yes	The ID of the disk to modify.	rcd-wz9c8isqly8637zw****
DiskName	string	No	The new name of the disk. The name must be 2 to 128 characters long. The name can contain letters (including English and Chinese), digits, colons (:), underscores (_), periods (.), and hyphens (-).	testDisk
Description	string	No	The new description of the disk. The description must be 2 to 256 characters long and cannot start with `http://` or `https://`.	test
DeleteWithInstance	boolean	No	Specifies whether to release the disk when the instance is released. If you do not specify this parameter, the current setting remains. This parameter is not supported for cloud disks with the multi-attach feature enabled. An error is returned if you set `DeleteWithInstance` to `false` in the following cases: The disk is an ephemeral disk (category: `ephemeral`). The disk is a basic cloud disk (category: `cloud`) that cannot be detached (`Portable=false`). Warning If you set `DeleteWithInstance` to `false`, the disk is still released with the instance if the ECS instance is security-locked. An instance is security-locked if its `OperationLocks` response contains `"LockReason": "security"`. In this case, the `DeleteWithInstance` setting is ignored.	false
BurstingEnabled	boolean	No	Specifies whether to enable performance bursting. Valid values: `true`: Enables performance bursting. `false`: Disables performance bursting. Note: An error is returned if you specify this parameter for a disk that does not support performance bursting.	false
