You can manage the array before the os boots via the card's bios, as
well as after via the MegaRAID Megamgr utility
The driver (megaraid_mbox) is included in the stock kernel. I haven't
had a chance to setup proper monitoring yet, but I do have the alarm
enabled, which will emit a horrendously loud neverending beep if a
problem is detected.
