Controller IDs (c<n>) are assigned based on the order the kernel probes the hardware. On the SPARC systems you can usually change this in the firmware (OBP), but they really don't _mean_ anything (other than the kernel found c8 before it found c9). There are (or were) other things the kernel considers a "disk controller" on the system beyond the three you indicate. Keep in mind that once the kernel finds a controller it makes an entry in /etc/path_to_inst so that the IDs remain consistent if new controllers are added (earlier in the search path). -- {--------1---------2---------3---------4---------5---------6---------7---------} Paul Kraus -> Senior Systems Architect, Garnet River ( http://www.garnetriver.com/ ) -> Sound Designer: Frankenstein, A New Musical (http://www.facebook.com/event.php?eid=123170297765140) -> Sound Coordinator, Schenectady Light Opera Company ( http://www.sloctheater.org/ ) -> Technical Advisor, RPI Players _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
