We have a shining new server with 5 6Tb disks. We don't have physical access to it, so any "in BIOS do X" stuff is out of the question.
I have been "forced" by the web interface of my to pre-format one of my disks, to install Windows.
After booting into Windows and installing MegaRAID manager, I have been able to create my RAID10 array as I wished, using the remaining 4 disks.
I want to create an additional disk using the remaining space on the system disk, but now I am stuck with a 3-part disk hitting the 2tb limit of Windows, and unable to use the last part of the disk. I can create a partition on the 1.7tb part, but can't do anything on the 3.5tb part.
I can boot up in Windows PE to format the system drive, and I don't have a problem with reinstalling the OS (it's virgin and has no data).
Thanks for your help! :)
