SiI 3114 not recognizing full capacity of RAID 5 array
Posted on 2009-05-14
I have a SiI 3114 SATA RAID pci controller in a Dell Dim 3000. Previously it was configured as a RAID 1 with two Seagate ST31500341AS drives attached. It worked fine. In the RAID config screen, the drives were recognized as having 1397GB and that was the size of the drive.
The problem was when I wanted to add a drive to it making it a RAID 5 array. I added a third Seagate (same model number) and the drives were all correctly recognized, but when I would try to create an Array, it would limit the size to 744GB. I would have thought the capacity would be 2794 (1397 x (3-1)).
Ive tried to flash the bios of the card, but I'm not having luck with that. Anyone have any other ideas. Why it would create such a small array size.
