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

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.

This API has been discarded. Use the API described in Querying the Target ECS Flavors to Which a 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 lists the parameters.

**Table 1** Path parameters
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the ID, see Obtaining a Project ID.

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.

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
instance_uuid	No	String	Specifies the target ECS ID in UUID format.
source_flavor_id	No	String	Specifies the source flavor ID.
source_flavor_name	No	String	Specifies the source flavor name.
sort_key	No	String	Specifies the field for sorting. Value options: flavorid: indicates the flavor ID. The default value is flavorid. name: indicates the flavor name. memory_mb: indicates the memory size. vcpus: indicates the number of vCPUs. root_gb: indicates the system disk size.
sort_dir	No	String	Specifies the ascending (asc) or descending (desc) sorting. Value options: asc: indicates the ascending order. desc: indicates the descending order.
limit	No	Integer	Specifies the maximum number of flavors that can be displayed on one page. The default value is 1,000.
marker	No	String	Uses the ID of the last flavor on one page as the paging marker.
