Hello.   What you are wishing to perform is referred to as Online Capacity Expansion (OCE) which is not supported by the H200 RAID controller neither does it support array re-tagging to enable you upgrade to 2 TB drives on the same Virtual Disk (VD). Ensure that you have backup of your data. The only option available for you is to delete the the existing VD and create another with the 2 TB drives. Re-install the operating system and restore your data.
I have a Dell PowerEdge R310 with the following specs: OS: Windows Server 2008 R2 Standard Raid Controller: H200 Raid Volume: 500GB Raid Layout: Raid-1 Basically what I want to know if is it possible is to install a larger drive (I would like to do a 2 TB drive) to replace both 500GB drives and expand the Raid-1 volume to the 2TB size, without losing the current data?
