This is using windows 2008 64bit server on HP DL160 G6 system. I have created one array using RAID 1+0, yielding 3.35TB partition (12 pcs of 600GB HDDs). After setting up the MS windows server, I found that there are only 2TB space on my C: drive.
I went to computer management > disk management, and found that 1.35TB is UNALLOCATED. Why? How can I resolve the problem?
