The SmartArray doesn't recognize the external array.
So thats why I connected it to a SCSI non-raid controller which does.
lvndiskscan on my Centos server even can tell the size of it.
/dev/sda [ 2.00 TB]
The external array has it's own built in raid controller.
The Bios the SmartArray said it was a raid 0 2048GB failed.
I not sure why the SmartArray sees it as that because the external array is
configured as a raid 5 with spares.
Im not familar with the SmartArray and don't have another to try.
Is there no way to access the data other than via the SmartArray?
