One interesting task to do but not so easy as i thought.
The server is HP DL320e gen8, The main difficulty is with partitioning the RAID1 (2x3TB HDDs) during the installation on 2 partitions (System = 200GB and Data = the rest of the space ~ 2.7TB) and all this under Windows Server 2012 R2 installation.
I tried using Diskpart on the partitioning step of the installation, by converting the drive to GPT and creating all the needed partitions for the system, but with no availability to continue the installation using this partitioning method.
And doing all this I think it's going to a dead end ...
If someone have any suggestions I'd be rather happy to discuss them. Thank you in advance!
