I am from installing Windows Server 2012 R2 on a Fujitsu Primergy TX300 S8 server.
This server has 8 x 4TB hard disks which I configured as RAID5. In the disk management it shows a total of about 21TB and I was able to create two partitions of about 1TB each where I loaded the OS and the other partition for Exchange Server.
The challenge is that am unable to allocate the remaining space for use. When I right click the functions to enable disk allocation they are greyed out. Kindly see the screen shot.
I need help with this one.
