Avid Raid Failure

Curious to know if anyone has ever encountered this experience. Came in Monday morning after a long break powered up the Array then brought the Avid up giving enough time for drives to completely come up first. Went into MC and began to capture and found no local storage was available. Then in turn rebooted the Avid and tried again still no media drives. Looked at the back of the array and found all drives on one side flashing red. No warnings indicated on the front of the chasis. Then in turn safely powered everything back down. Brought the raid back up and everything returned to all green. However after rebooting the Avid and launching MC again still no drives. Went into disc manager and found that I lost the stripe set and a new unallocated disc was available and the orginal disc 2 was missing. Checked through hyperterminal on both channels no errors were indicated. Contacted Avid support and they said looks like I lost all my media and I would simply have to reload in a very casual way. Totally surprised I asked what could have happened no one seemed to have an explanation. I was totally baffled since this is suppose to be raid 5 protected. They finally decided to send a new controller card but still gave no guarantee of getting media back and they were right lost everything. Did a low level format through the array's firmware all 10 drives checked out okay. Restriped through firmware and then striped across the 2 drives through windows OS. Everything seems to be fine. I am lost for words as to what has happened and if anyone has experienced this or has any ideas or theories would love to hear them.
My system specs are
MC 2.8.1
HP XW8200 Nvidia Quadra 1600
3 Gig Ram
RTX320 Fully Populated striped acros the bus

Hi Rodney,
Not knowing the specifics of this case, I can only clarify that the VideoRaid is a hardware raid 3. This allows for one drive to shutdown or fail in each channel and still see data. From what you indicate, it was a full shutdown of one of the channels. Being a striped set, you would not be able to see the data. It was determined that replacing the controller was needed and corruption of the stripe set had taken place. I would be available anytime to discuss your Avid VideoRaid concerns. Please do not hesitate to call.
