Ok,big thanks for Your help.
I guess it's rebuilding again. I see that an array is degraded and data is being copied from one disk to another.
It shows that all the driver does is showing virtual disks (arrays) like if it was only one disk and is rebuilding by itself on a hardware layer.
I will keep trying to gather more information on that subject.
If anybody else could write something interesting then please do.
Another thing I'm curious about is connecting to Intel Raid Web Console from remote. I'd have to check the arrays from remote and manage it.
