The array that I'm tyring to recover is a SCSI-toSATA 2U external Raid
It connects to any u320 controller and is suppose to show up to Linux as 1
Quote from the manual:
"These host interfaces are host O/S independent and will operate on any
system that has a working SCSI or Fiber interface
The DAS is made up of several components including a RAID controller,
backplane board with intelligent environmental monitoring, chassis, power
supplies, fans, front control
panel with LCD display and hard drive bays."

All the drive are in the external array, and it says the Array is

The Smart Array card that it was originally connected to doesn't recongize
The SmartArray is in a working server and is currently running an internal
My guess is there was some hardware failure on the external side of the
controller or the external array.
My reasoning for this, is if I connect the A Channel of the external array
to my Centos server
my SCSI card doesn't recognize it. But if I connect it to the B channel side
I would love to be able to connect the external array to another SmartArray
controller and see if it recogizes it, but I don't have one.
