Changing from JBOD to RAID 1
Hard drives that aren't in a RAID array will have the status "Normal". You must have at least two drives that are not in 
a RAID array to build a new RAID 1 array with RMM. Building the RAID 1 array will save the data on one of the drives 
and overwrite the data on the other drive. You will be able to choose which drive's data to keep.
In Advanced Settings, click Drives.
Click 
 to the right of "RAID".
Choose a RAID array.
Set the RAID mode to "RAID 1".
Check "Add a disk to RAID array with RMM. Your data will be preserved.".
Select the drive whose data will be saved from the drop-down menu.
Select the drive to add to the RAID array.
Click Create RAID Array.
The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
