ChangeNodeTypes-阿里云帮助中心

Upgrades or downgrades node specifications. Ensure that node resources meet the target specification requirements before you call this operation. If a node does not meet the requirements, the task reports success but the specifications remain unchanged. To confirm a successful change, query the node after the task completes 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.

Request parameters

Parameter	Type	Required	Description	Example
NodeType	string	No	The node specifications. Valid values: zeroLeni-ebs : zeroLeni-ebs ebs-enhanced : ebs-enhanced cpfs-enhanced : cpfs-enhanced zeroLeni-cpfs : zeroLeni-cpfs	cpfs-enhanced
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 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 the precheck, no task is generated. You can submit up to 10 nodes per request.

RequestId	string	The request ID.	887FA855-89F4-5DB3-B305-C5879EC480E6
TaskId	string	The task ID. Returned only if all nodes pass the precheck. Empty if an exception occurs.	i158475611663639202234
NodeResponse	array<object>	The responses for the nodes.
	object	The response for a single node.
Code	string	The response code for the node. Valid values: STATE_INVALID : The node is in an invalid state. NOT_SUPPORT : The node does not support the target specifications. RESOURCE_INSUFFICIENT : Node resources do not meet the target specification requirements. PASSED : The precheck passed.	PASSED
Message	string	The response message for the node.	success
