Adaptec 4000SAS RAID Controller
Posted on 2012-08-15
We are trying to re-purpose a 3 year old server. It originally had 2 RAID arrays - one RAID 1 with two 80GB drives for the OS, then six 500GB drives in a RAID 5 for data. The RAID controller is an adaptec 4000 controller. The drives are all SATA. The RAID 5 was working fine until we replaced the drives.
I replaced the six 500GB drives with new 2TB drives. I left the two 80GB drives there to continue to run the OS. Now when I go into the RAID controller configuration utility, I still see the RAID 1, but I cannot create a new array with the new drives. If I go into the drive selection utility I can see the 6 new drives and even perform a format, but when I go into the array configuration utility I cannot select any of the new drives, I cannot initialize the drives - it's like the aren't there.
I am thinking that the drives just are not compatible with the controller - although I have not seen anything in any documentation that identifies maximum drive size or any other limitations on the drives. Does anyone have any other suggestions before I start thinking about plan B?
Thanks in advance.
