Attach external disks at particular position - ibm-cloud

Question

By using this code i can attach disks sequentially.
device 2, device 3, device 4
But i want to attach disks for a particular position.
I want to directly attach 3rd disk or 4th disk.
Without upgrading the previous disks
code
for disk in external_disks:
obj = {}
obj['id'] = getDiskPriceId(client, disk)
#obj['id'] = 2277
#logger.info("disk %s size: %s --\n" ,(str(disk_num)), (str(disk)))
if obj['id'] == "":
print("Invalid external disk size")
exit(1)
categories = {}
categories['categoryCode'] = "guest_disk"+str(disk_num)
categories['complexType'] = "SoftLayer_Product_Item_Category"
obj['categories'] =[categories]
obj["complexType"] = "SoftLayer_Product_Item_Price"
prices.append(obj)
disk_num = disk_num + 1
response = client.call('SoftLayer_Product_Order','placeOrder', {
"virtualGuests": [{
"id": id
}],
"prices": prices,
"properties": [{
"name": "NOTE_GENERAL",
"value": "adding disks"
},{
"name": "MAINTENANCE_WINDOW",
"value": "now"
}],
"complexType": "SoftLayer_Container_Product_Order_Virtual_Guest_Upgrade"
})

Answer 1

You can attach directly to an specific position through the attribute categoryCode, following is the order:
guest_disk1 for Second Disk
guest_disk2 for Third Disk
guest_disk3 for Fourth Disk
guest_disk4 for Fifth Disk
Make sure that item prices have the categoryCode you need, you can verify it by using the method SoftLayer_Virtual_Guest::getUpgradeItemPrices as following:
https://[username]:[apikey]#api.softlayer.com/rest/v3/SoftLayer_Virtual_Guest/[deviceId]/getUpgradeItemPrices
Following structure about prices allows to attach disks directly to the Third and Fourth position.
prices = [
{
'id': 2299,
'categories': [
{
'categoryCode': 'guest_disk2',
'complexType': 'SoftLayer_Product_Item_Category'
}
],
'complexType': 'SoftLayer_Product_Item_Price'
},
{
'id': 2288,
'categories': [
{
'categoryCode': 'guest_disk3',
'complexType': 'SoftLayer_Product_Item_Category'
}
],
'complexType': 'SoftLayer_Product_Item_Price'
}
]
In your code the disk_num value needs to be between 2 and 3 to attach disks directly to the third and fourth position.
Note:
If you want to change/replace disk by another one with more/less space, you only need to apply the same idea. Set the categoryCode of new disk with the same categoryCode value of current disk.
I hope this help you.
