Querying the Target Flavors to Which an ECS Flavor Can Be Changed

Function

An ECS flavor cannot be changed to certain flavors. This API is used to query the target flavors to which a specified ECS flavor can be changed.

URI

GET /v2.1/{project_id}/resize_flavors?instance_uuid={instance_uuid}&source_flavor_id={source_flavor_id}&source_flavor_name={source_flavor_name}&sort_key={sort_key}&sort_dir={sort_dir}&limit={limit}&marker={marker}

Table 1 describes the parameters in the URI.

Table 1 Path parameters

Parameter

Mandatory

Description

project_id

Yes

Specifies the project ID.

Note

One of the instance_uuid, source_flavor_id, and source_flavor_name parameters must be configured. If multiple parameters are configured, the system processes the instance_uuid, source_flavor_id, and source_flavor_name parameters in descending order by default.

Table 2 describes the query parameters.
