If either disk fails while in a fully mirrored state, the system continues to 
operate. The disk LED states described in

has failed. In addition, the Disk Status window in NBX NetSet shows the 
status of your disk drives.

To verify the status of a disk drive, select Reports > System Data > Disk 
Status. See the Help for information on verifying disk status.
