T-10 ALUA/TPGS support

Hi, another question about our HDS 9520V.  Thanks again to all who helped us with Solaris-9 mpxio, it seems to be working just fine.  We're now setting up a Solaris-10U2 (06/2006) SPARC machine to use some LUN's on the 9520V array, and Sun docs state that their current mpxio multipath drivers support asymmetric arrays which comply with the T-10 ALUA (TPGS) standard.

So, the question is, is it possible to set host-group/options on the array so the 9520V will speak TPGS for asymmetric LUN failover?  It looks like Linux MPIO checks for a TPGS bit being set as well as Solaris-10.  How about ALUA/TPGS support in newer arrays like the AMS (I"m assuming that is an asymmetric array as well, sorry if I'm wrong about that)?

Thanks and regards,
