Platform For AI:ChangeNodeTypes

Last Updated:Dec 26, 2025

Upgrades or downgrades the specifications of one or more nodes. Before you change the specifications, ensure that the node resources meet the requirements of the target specifications. If a node does not meet the new specification requirements, the task reports success, but the specifications are not changed. Therefore, do not rely on the task status. To confirm a successful change, query the node after the task is complete and check the returned specifications.

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.

NodeIds

array

No

A list of node IDs. You can specify a maximum of 10 nodes in a single request.

string

No

The node ID.

['2423423423423']

All nodes for which you want to change specifications must be in the `Using` state and belong to the same node group. An asynchronous task ID is returned only if all nodes pass the precheck. If any node fails this check, no asynchronous task is generated. You can submit a maximum of 10 nodes in a single request.
