I have spend some time at a customer site helping to build HYPER-V environment. Even though the project was medium scale I learn lot during that time.
1. Never run into HYPER-V setup without checking SAN storage compatibility. Some SAN storage required you to install the certain software into the server. I learn that hard way. You can always run *.exe programs by command prompt at server core.
2. Always keep the server core commands nearby you. Microsoft has already provided the reference sheet like that. If you can’t keep it then try to remember the command ‘sconfig’ this command work in Windows 2008 R2 core edition. If you prefer third party free tools then consider Core Configuration (There maybe some other nifty tools as well)
That is for now folks, catch ya later!
