What do you actually mean by this? Expanders are in use
in the Jxxxx series, they show up as sgen (or ses) devices.
Expanders respond to SCSI Enclosure Services commands.

To the best of my recollection, there's no command interface
for SAS Zoning in OI or Solaris 11, but if you want that
you should be able to bolt things together using the usmp(7i)
interface.
