Hi I have 2x HP DL 380 G6 Servers with Windows 2008 R2 Datacenter and Windows server 2012 R2 datacenter which are hyper V servers. Until now everything was fitting 2TB RAID 5 . Recently I added new HDDs and nothing above 2TB is recognized. I assume that it is because at the beginning I formatted drive as MBR. Now I assume that I need to convert to GPT.
The question is what would you do (or even better what you did and your experience in that manner)
Online conversion MBR to GPT with some software (if you have any proposal I would be thankful)
Offline conversion - to delete and recreate raid format as GPT .......
