mpxio with DEC HSG80

Hello managers,

         I have a V490 with Solaris 9 09/05 freshly installed (my
application isn't qualified under Solaris 10). I have two Qlogic QLA2300
cards connected (through fabric) to a DEC HSG80 controller. After
installing the Qlogic QLA2300 driver, I see the LUN for the disk 4 times,
as expected since there are 4 paths.

         I would like to setup mpxio to multipath the IO to that LUN. I
tried enabling mpxio in scsi_vhci.conf, and adding:

device-type-scsi-options-list =
"DEC HSG80", "symmetric-option";
symmetric-option = 0x1000000;

         I've tried various combinations of spacing on the "DEC HSG80" line
followed by reconfiguration boots and I don't get any new devices. I saw
a couple year old posting with a similar question, but no summary.

         I was hoping to avoid using HP's SecurePath product if at all
possible given its price tag.

         I've also read conflicting information on whether or not any of
the Sun SAN Foundation packages need to be installed. Since I don't have
SUN FC cards, I'm guessing I don't.

         Also, assuming its possible to get this to work, should I be able
to boot off of it?

Thanks,
