It's not broken any more, because I fixed it. http://blogs.sun.com/jmcp/entry/on_stmsboot_1m 6707555 stmsboot is lost in a ZFS root world patched in 140334-01 and 140335-01. Rolled into S10 Update 7. There have been some followon fixes. There is no reason to edit fp.conf or mpt.conf yourself, unless you must use per-hba MPxIO. In which case, make darned sure you run /usr/sbin/stmsboot -u afterwards. > Also, since I'm up late and posting a comment anyways, I set up a V890 > with mpxio and ZFS with every ZFS mirror being composed of a mpxio enabled > device.

On X86 with fc, MPxIO is the default, but that is the only case where that is true at this point in time. James C.
