I am using a Mylex Disk Array Controller with a Raid 5 system. I have 4 drives and I am adding 2 more identical drives to my set. I have them installed in the server physically.
My question is, "What steps do I take to add the two drives to my server and add them to the Same volume set?"

You may not want to here it but.... Back up your Data. Create a new raid 5 volume with the new disks, and restore the data. You may want to consider using 5 disks in your raid 5 set and use the 6th disk as a failover. This way the sixth disk will come online automatically if a drive fails, and you will only have a brief performance hit while the striped set is being rebuilt. I'm not familiar with your controller, but you should be able to configure the sixth disk as a failover
