But this still requires >the system to have an enclosure service of some sort. All: At home, I have used gpart labels to identify drives (14 drives) which obvi= ously doesn't scale well. Do the patches get one to a point of identifying drives as lon= g as you have controllers and backplanes supporting say SGPIO e.g. LSI/Superm= icro? Can you expound on what the 'service' would provide in addition to the patc= hes? This link is informative but leave questions for the reader. https://people.freebsd.org/~mav/Enclosure_Management_en.pdf Where are your patches located? I would very much like to learn more as to how best to handle enclosure management under FreeBSD, or to know that in fact it is not generic enough and that it will always be hardware (backplane/expander/controller) dependent for any implementation requiring programing skills or vendor supplied tools.
