Yet neither Sun nor HP agrees - they both say that Hitachi has not yet released the microcode necessary to enable this capability - and in fact, external storage cannot be selected when creating HDP volumes. Additionally, TSM does not recognize HDP volumes at all, making it impossible to migrate to/from thin volumes with this utility, even within the array (much less with externally virtualized storage). What is your explanation for why your claims differ so significantly from what your OEM and Reseller say actually works?
