[allmightyspiff]

$ slcli -v block replica-order 8666387 -s WEEKLY -l dal13
Calling: SoftLayer_Network_Storage::getObject(id=8666387, mask='billingItem[activeChildren,hourlyFlag],storageTierLevel,osType,staasVersion,hasEncryptionAtRest,snapshotCapacityGb,schedules,intervalSchedule,hourlySchedule,dailySchedule,weeklySchedule,storageType[keyName],provisionedIops', filter='None', args=(), limit=None, offset=None))
This volume is set for cancellation; unable to order replicant volume

Error is because of this line: https://github.com/softlayer/softlayer-python/blob/master/SoftLayer/managers/storage_utils.py#L663

In rest, the billingItem looks like this:

Also TODO, look over storage_utils to see if there are any other instances of checking against literal '' string.

if volume['billingItem']['cancellationDate'] != '' should be if not volume['billingItem']['cancellationDate']. In python '' and None both equal False.
