Is there a mangement interface program for the "mfi" driver somewhere? I rooted around in "ports" but didn't find one, nor on the base system. The Linux ones want to talk to the "amr" driver which is the older LSI Logic MegaRAID boards, not the newer ones that the mfi driver talks to. No management tool = el-sucko, because you can't rebuild a failed disk or even shut the alarm on the board off! -- Karl Denninger karl@denninger.net
