Just to follow up on this, in case there are others interested:
To get multipathing, you need to configure the scsi_vhci driver, in /kernel/drv/scsi_vhci.conf for sol10 or /etc/driver/drv/scsi_vhci.conf for sol11-x86. To get better performance, you probably want to use load-balance="logical-block" instead of load-balance="round-robin". See examples below. You may also need to run "stmsboot -e" to enable multipathing. I still haven't figured out what that does (more than updating /etc/vfstab and /etc/dumpdates which you typically don't use with ifs), maybe nothing.
The supported way to enable MPxIO is to run # /usr/sbin/stmsboot -e You shouldn't need to do this for mpt_sas HBAs such as your 9205 controllers; we enable MPxIO by default on them. If you _do_ edit scsi_vhci.conf, you need to utter # /usr/sbin/stmsboot -u in order for those changes to be correctly propagated. You can (and should) read about this in the stmsboot(1m) manpage, and there's more information available in my blog post http://blogs.oracle.com/jmcp/entry/on_stmsboot_1m James C.
