Ouch. Short comment, it might not worth it. Seriously. Does the P400 have a battery-backed cache? If yes, it will be MUCH easier to simply let it handle RAID5/10 and use stripe config for zfs. HW controllers with battery-backed cache will reduce the possibility of raid5 write hole. Depending on what your goal is, it might be the best choice. > But when I remove a disc and then reinsert it I cannot get ZFS to accept it > back into the array see bellow for the details.

Yet you're stuck with a hardware that practically does not allow you to do just that. > 1779-Slot 1 Drive Array - Replacement drive(s) detected OR previously failed > drives(s) no appear to be operational > POrt 2I: Box1: Bay3 > Logical drives(s) disabled due to possible data loss. > Select "F1" to continue with logical drive(s) disabled > Select "F2" to accept data loss and to re-enable logical drive(s) >From this output, the HW controller refuses to enable the removed disc, so that the OS (and thus zfs) can't see it yet. You can enable it from BIOS during booting (which kinda defeat the whole hot-swap thing), or you might be able to find a way (using ILO perhaps, or with some HP-supplied software installed on the OS that can talk to P400) to enable it without having to reboot.
