Get a disk identifier for iscsi device from SL API

I am trying to obtain an identifier for a iscsi disk I have provisioned using SL API. What is the best approach to do this? I can use the device name (as seen from the SL Portal) or wwn (600*) or even iqn. I just need a method to get this identifier for the just provisioned disk.

I will use either Python or Java.

Try the following python script:

"""
Retrieve block volume information.

This script makes a single call to the getIscsiNetworkStorage() method in the
SoftLayer_Account API service and uses a object mask and filters to get more
information about the block volume.

Here is the code that provides a partial value of the wwn or page83 id of the provisioned disk.

import pprint
import SoftLayer
api_username=<user name>
api_key=<api key>
client = SoftLayer.Client(username=api_username, api_key=api_key)
accountService = client["SoftLayer_Account"]
storageId = <storage id>
networkStorageService = client["SoftLayer_Network_Storage"]
result = networkStorageService.getProperties(id=storageId)
for record in result:
   for attribute,value in record.iteritems():
       if attribute == "value" and value.isalnum() and len(value) == 24:
          print "Page 83 ID for " + str(storageId) + " is " + value
