smp_utils is a package of command line utilities for accessing and controlling SAS expanders via the Serial Management Protocol (SMP). See this page: http://sg.danny.cz/sg/smp_utils.html for more information. This package was written for Linux and has been ported to FreeBSD (starting at smp_utils version 0.97b1). It uses the extensions to CAM added in late 2010 and only found in the yet to be released FreeBSD 9.0 . A quirk of the CAM extensions is that SAS expanders (more precisely SMP targets) are not visible in the user space. CAM assumes there will be a "twin" SES device (true for the SAS-2 expanders I have) on the same silicon as the expander. Hence invocations look like this: smp_discover /dev/ses2 camcontrol has been extended in FreeBSD 9.0 to access some SMP functions. smp_utils version 0.97b1 supports all functions defined in SAS-2 (up until the lastest draft: spl2r02.pdf) and that includes zoning support. Doug Gilbert P.S. For at least the last 3 years I have been unable to post to this list. The postmaster@freebsd.org informed me that my email domain was blacklisted. Not bad for a grand-fathered email domain that probably hasn't added a new email account in 10 years! FreeBSD's blacklisting probably dates from a period when some crazy service in the US identified every major and minor Canadian email domain as full of spammers. So anyone else who feels they have been blacklisted, contact the postmaster.
