Dell Power Edge Raid Array Issue

Hello Experts,

     I have a friend of mine I&#39;m trying to help but don&#39;t think there is much we can do.  He has a HP Server connected via SCSI to a Dell Power Vault using Power Edge Raid Controller.  He had a power outage and upon turning everything back on the LEDs on the drives are all green but the controller has long beeps and shows failed drives when you go into the Raid Bios.  There are 12 drives with two arrays of 6 drives.  Each array has 3 failed drives.  Is there any hope?  What&#39;s his best options?  He tried to rebuild the drives but it errors out.  

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.

Disaster Recovery

RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance. 

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.
