I used the HP Smart Array Configuration utility to setup a RAID 1 array (hardware P400 controller) using four disks. I created 2 logical drives with physical hard drive 2 mirroring drive 1 (o/s drives) and physical drive 4 mirroring 3. After upgrading to Windows Server 2008 R2, my RAID array is not visible under disk management (should it be?).
What is visible is drive c (Disk 0 - which are drives 1 & 2) listed as basic but with the capacity of just one drive. The other drive (Disk 1) also shows as basic with the capacity of a single drive but unallocated (it has no drive letter).
Both drives, however, show online leading me to believe that the RAID configuration is functioning somehow. Also, when I check the status with the Configuration disk, it shows that it's setup properly. Anyone have any ideas? How can I even access the unallocated drive for use?
