You can just let it sit in the BIOS of the SmartArray controller it will
rebuild there too. Or you can download the SmartStart CD and boot it.
Run the Raid management tool from there to see progress.

The disks itself carry the information about the raid, so if you have
another server with any SmartArray supporting raid5, you should be
able to plug them in there and let it rebuild. It might warn about
drive position movement and cache memory changes.
