Hello, here is a note describing the lego blocks needed to have a fully operational multipath stack with StorageWorks and Qlogic hardware. Kernel : ======== 2.6.12-rc6 Additional patches : ==================== Qlogic : LU scaning fix http://marc.theaimsgroup.com/?l=linux-scsi&m=111836291000433&w=2 Qlogic : Postpone fc_rport block/unblock to scheduled work http://marc.theaimsgroup.com/?l=linux-scsi&m=111868700022257&w=2 Mike Christie : export block layer function https://www.redhat.com/archives/dm-devel/2005-June/msg00084.html Hardware Handler module : ========================= Mike Christie, Christophe Varoqui : http://christophe.varoqui.free.fr/multipath-tools/dm-hp-sw.tar.bz2 Multipath Tools : ================= git HEAD up to commit fd9857d2eb9796d0a205887bdff879d56355eda2 at minimum : http://kernel.org/pub/scm/linux/storage/multipath-tools/.git Configlet : =========== device { vendor "COMPAQ" product "HSV110 (C)COMPAQ" path_grouping_policy group_by_serial path_checker hp_sw features "1 queue_if_no_path" hardware_handler "1 hp_sw" } It would be good to have the kernel patches pushed to 2.6.12 before it comes out. Happy testing, cvaroqui - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
