| serverImageProductCode | Conditional | String | Min : 1, Max : 20 | Product code of SW(OS included) installed to a server image Either of memberServerImageNo or serverImageProductCode parameter shall be designated. However, both can be designated together. |
| serverProductCode | No | String | Min : 1, Max : 20 | Server product code regarding server HW spec |
| memberServerImageNo | Conditional | String | - | My server image number created by a user. Either of memberServerImageNo or serverImageProductCode parameter shall be assigned. However, both can be assigned together. |

| initScriptNo | No | String |  | The server runs the initialization script that you set at first boot. Passes the initialization script number of the initialization script as a parameter.
