(or redirect me to a more appropriate maillist). After many unsuccessful trials and googling, we had to reconfigure the adapter from RAID mode to IT mode. It required flashing the adapter's BIOS from a Supermicro-supplied image and changing a jumper setting on the motherboard. Now as the adapter is in IT mode, it is a plain HBA the BIOS can boot from, and I have set up a gmirror on the SAS disks. After flashing the adapter BIOS, don't forget to enter its setup (Ctrl-C) and enable hotplugging of disks (called "Removable Media Support" in the menu, off by default).
