Re: mounting RAID on linux-bbc?

RH kernels usually ship with a number of hardware RAID drivers compiled
into the kernel.  You will need to know what kind of RAID you are using
and if it is hardware or software RAID.

You may want to make sure it is software RAID first, because I believe 
Jeff's response is for software RAID.

If it is hardware RAID, you will need to make sure you have the device
driver for the RAID controller.  Once that is loaded, you will see your
RAID disk(s) and be able to mount the partitions.

Cheers,
Ed
