(Stock RedHat 6.2 w/o modules)

I hadn't thought of that - thanks! I used an initial
ramdisk to start up the array, but this will be alot
easier.

I get a error in ll_rw(something or other) when it
tries to mount the non-started array.

I'm fairly sure that the problem is with the BSD
disklabel partitioning scheme I had to use with the
SRM console.

How are you booting your system?

Is there any way to replace SRM with something that
could boot off regular partitions?
