Request Parameters
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
oper_type |
Yes |
String |
Change type. Options:
|
new_storage_space |
No |

new_product_id |
No |
String |
This parameter is valid and mandatory when oper_type is set to vertical. |
new_broker_num |
No |
Integer |
Broker quantity. This parameter is mandatory when oper_type is set to horizontal. |
publicip_id |
No |
String |
ID of the EIP bound to the instance. Use commas (,) to separate multiple EIP IDs. This parameter is mandatory when oper_type is horizontal and public access is enabled. |
