SoftLayer Evault verify API error - api

Question

I control the softlayer resources(Server, Storage etc) by JAVA API.
I am verifying an upgrade to the Evault storage space ( 20GB => 40GB) via the API but the API returns an error message
"error": "EVault service already exists for the requested location (Seoul 1).",
"code": "SoftLayer_Exception_Public"
from the POST event
URL(POST) https://IBMxxxx:xxxxx#api.softlayer.com/rest/v3/SoftLayer_Product_Order/verifyOrder.json
Here is the attached request body
{"parameters":
[
{"complexType":"SoftLayer_Container_Product_Order"
,"orderContainers":[
{"complexType":"SoftLayer_Container_Product_Order_Network_Storage_Backup_Evault_Vault"
,"location":"1555995"
,"packageId":0
,"quantity":1
,"virtualGuests":[
{"complexType":"SoftLayer_Virtual_Guest"

],
"useHourlyPricing":false
,"prices":[
{"complexType":"SoftLayer_Product_Item_Price","id":66257}
]
}
]
}

}

What you are doing with that request is ordering an eVault storage, besides the itemId set is for a 60GB EVault Disk capacity and not 40 Gb.
UPDATE
Retrieve item prices only for eVault storage capacities.
https://IBMxxxx:xxxxx#api.softlayer.com/rest/v3.1/SoftLayer_Product_Package/0/getItemPrices?objectMask=mask[id,locationGroupId,item[id,keyName,description],pricingLocationGroup[locations[id,name,longName]]]&objectFilter={"itemPrices":{"item": {"keyName":{"operation":"*=EVAULT"}}}}
Currently to perform an upgrade what you require is to use the method SoftLayer::upgradeVolumeCapacity, please see following request:
Perform capacity upgrade to an specific eVault storage:
(url POST) https://IBMxxxx:xxxxx#api.softlayer.com/rest/v3/SoftLayer_Network_Storage/eVaultId/upgradeVolumeCapacity
with the following request BODY:
{
"parameters":
[
559
]
}
Do not forget to change eVaultId on the request for your eVault storage, try this rest request to retrieve the specific eVault id:
Retrieve an account's associated EVault storage volumes:
https://IBMxxxx:xxxxx#api.softlayer.com/rest/v3/SoftLayer_Account/getEvaultNetworkStorage?objectMask=mask[id, serviceResourceName,guestId,billingItem[id,location]]
Once obtained, then you may specify an upgradeItem (e.g. "itemId": 559 that might be the itemId for 40 Gb evault disk).
To retrieve the upgrade itemId's for the different upgrade capacities allowed, use the following request:
https://IBMxxxx:xxxxx#api.softlayer.com/rest/v3/SoftLayer_Network_Storage/eVaultId/getObject?objectMask=mask[id, billingItem[id, upgradeItems[prices]]]
(don't forget to change the eVaultId).
Review the upgradeItems property and choose the capacity required, you should use the id value for the capacity you need on the method upgradeVolumeCapacity.
