Description
BAD
$ slcli -v block replica-failback 41442919
Calling: SoftLayer_Network_Storage::failbackFromReplicant(id=41442919, mask='', filter='None', args=(None,), limit=None, offset=None))
GOOD
slcli -v call-api SoftLayer_Network_Storage failbackFromReplicant --id=6548079
Calling: SoftLayer_Network_Storage::failbackFromReplicant(id=6548079, mask='', filter='{}', args=(), limit=None, offset=None))
failbackFromReplicant doesn't accept parameters, so that needs to be changed in the manager.
failoverToReplicant doesn't take an immediate parameter either, which the manager is sending. So that hsould be fixed.
