Winston, One thing I must know is the controller installed in the server. If you have a H700 then YES you can. It is referred to as a Raid Level Migration. It is as easy as doing a Reconfigure from OpenManage and then selecting the disk you wish to add.  Now if you have an H200 or SAS6/iR then Raid Level Migration is not an option and the only way to do this would be to recreate the array.  Now if you have the H700 then as I stated you go through OpenManage and do a Reconfigure. The data should be fine, but we always suggest backing up the data prior to doing anything within the controller. Just in case. You can find out more about Raid Migration on page 31 here - [URL] Let me know if this helps.
Hi, I just installed Windows 2008 on my Dell Poweredge R310 using one Hard disk only that I've configured through RAID management. Now after installation, I want to add another physical hard disk to serve as additional drive on my windows OS to serve as a simple storage for any files (Drive D:).  Do I need to go through Raid Configuration again? what will I choose, Import Foreign or Clear configuration at the promp? I am afraid maybe I will lose the data on my previous disk and Install the OS again from the start. If anyone can suggest steps to do this I would really appreciate it. Thanks!
