Hi there,
I have a Virtual Windows 2003 Server with 2TB RDM. Department is upgrading to Server 2012R2.

I created a Physical Copy of VV on 3PAR. I set the new destination volume 2.5TB So 2TB data copied to 2.5TB VV

Promoted Physical Copy and exported to VMware host. I had bunch of problem bringing the new VV on the new server because Microsoft again managed to make everything so complicated on 2012R2. Anyway I managed to bring the disk up on Server 2012

The lun added to virtual server 2012 as RDM

But it shows 2.5TB disk with 2TB partition and 0.5TB unallocated partition.

I tried everything diskpart, dell extpart utulity, disk management but I wasn`t able to extend that 2TB to 2.5TB

What did I do wrong here?

At a guess your hitting the max partition size for a Windows basic disk which is 2TB's.

You need to either switch the disk to dynamic and chain several LUNs together (not recommended)

Or you need to change the disk to use GPT -http://www.thewindowsclub.com/convert-mbr-to-gpt-disk

Sounds like you have a MBR disk and need a GPT, you can not convert a MBR to GPT without losing data, you can convert to a dynamic disk, but note that if I recall VSS does not support dynamic disks if you need to do VSS level backups.
