The type of the new private pool.
Operation description
A private pool is generated after an elasticity assurance or a capacity reservation is created. The private pool is associated with information about the instances that are created by using the resources in the private pool. When you create ECS instances, you can configure the instances to use private pool resources, matching them to active elasticity assurances or capacity reservations.
-
This operation does not require you to restart the instances for the changes to take effect.
-
When you call the following operations on an instance, the system attempts to match the instance with active private pools. If the instance is configured to a specific private pool. the call may fail because the private pool is no longer active or does not have sufficient resources. If the call fails, call the ModifyInstanceAttachmentAttributes operation to change the match mode of the private pool to
Open.- StartInstance: starts an instance that is stopped in economical mode.

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.
