The ominous 'Storageworks handler' Ben referred to is actually the hp_sw hardware handler available in later versions. This firmware requires a 'START STOP UNIT' command to be send to the inactive path; the firmware will then activate it (and deactivate the old path). Hence you're pretty much stuck without it. So a firmware update would be your best option here.
