Something I just came across which may be useful to those using Storage Agents:
  http://www.ibm.com/support/docview.wss?uid=swg21155034
(Don't ask me why this information could not have been added to an online PDF
manual in the intervening six months.  Institutional inertia in producing
documentation prevents customers from gaining full benefit from IBM products;
which is a shame, given the work that developers put into creating features.)
