The tool you need to look into is: sysutils/aaccli . I think arctool  
is only for arcmsr-devices.
unfortunately aaccli doesn't provide the possibility to use it with  
parameters, so you probably
need to use it with an expect-script.

On the adaptec 2410SA I activated the "alarm" feature in the  
controller bios, which helps me,
because its a home server but this will not help you if your server is  
sitting somewhere else.

Because of this limitation (and a few other things with the  
controller) I'm certainly looking for
an other solution. In my case a ZFS-based software RAID will suffice,  
but this might not be
desirable for you.

Take care & good luck,
