S/N 5C7208P1ET PID: 658553 hp proliant microserver n40l I created a RAID 1 on two 2TB Hard Drives. The Hardware RAID created the drives correctly. I loaded the Operating system. The Operating system worked correctly. Then I decided to test that it did duplicate the Operating by removing one Hard Drive, which it did work. I have also tested that there is nothing wrong with both Hard Drives. I plugged back the Hard Drives back in the bays that I pulled them out. Know it says critical status A disk member of an array has failed or is not responding. Please refer to your AMD User Manual for further details.
