Hi Liujun, The group I am part of works on SAS mpxio. We support mpxio for SAS if you are using the mpt driver and either - Solaris Nevada, or - Solaris 10 Update 4 + the patch which should be released in about 6 weeks or so. (I integrated the changes we need for this into Solaris 10 Update 5 last weekend). Expanders don't belong to a host - they don't respond to the standard SCSI INQUIRY(6) command. We do have plans to provide access to expanders, but those plans have not yet solidified. What other questions do you have about SAS multipathing? James C.
