Elastic Compute Service:DeleteDisk

Last Updated:Jun 18, 2026

Releases a pay-as-you-go data disk. Supported disk types include basic disks, ultra disks, standard SSDs, and enterprise SSDs (ESSDs).

Operation description

When you invoke this operation, take note of the following items:

  • Manual snapshots of the disk are retained.

  • You can invoke ModifyDiskAttribute to specify whether to retain or release automatic snapshots along with the disk. Delete unnecessary snapshots promptly to maintain sufficient snapshot quota for epoch-based automatic snapshot policy execution.

  • The disk must be in the Unattached (Available) state when you release it.

  • If the disk with the specified ID does not exist, the request is ignored.

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.
