Trying to get Windows Server 2012 running on a PowerEdge 2900 (ST B3LPJH1 if that helps)
System has a Perc 6i controller and 8x 1TB SATA drives
I was going to do 500GB for the System drive and use the rest for storage; however, the system does not seem to want to accept that. Is there a trick to getting that to work? I'd even accept one giant RAID 5 drive; but, I cannot even get that for some reason
What are you seeing when accessing the controller? If you go to the Physical disks can you see all 8 listed, or only a few? If this is the case, I would check to make sure that both the SAS A and SAS B cables are connected from the controller, to the backplane. Also, are you seeing an error when attempting to create the arrays?
Let me know what you see.
I see all 8 SATA drives
If I set it as one giant RAID 5 array, when it gets to wanting to installing Windows it actually sees all the available space; however, splits it up into two Disks (Unallocated Space) and does not let me delete one and what not
Likely the issue is the Windows version, which has a 2TB limit for MBR formatted disks. What you can do is create the OS Raid 1 you discussed and then install the OS. After that create the other, larger array, and then after it is initialized format it GPT, which can exceed the 2TB limitations.
