What OS are you running? Not all OSes can use virtual disks over 2048GB (2TB) in size, and those that can go over 2TB, need to have had their partition table changed to GPT before the first partition was ever put on the disk. If you're running Windows, go to disk management, right click the MD's disk (not the partition), select properties, select the volume tab. Look for the partition style. It should read MBR or GPT. If you're running linux, do an fdisk -l on the disk and I think that's where you would see the GPT partition style.   Edit/addition: Once you know if you can use diskspace over 2048GB, check out this old post with my instructions on how to grow a virtual disk.
I put a 1TB SAS drive into the powervault. The Modular Disk Storage Manager recognizes the hard drive (it says unconfigured capacity 931.013 GB). From thee MD Storage Manager I click on the summary tab then click  Disk Groups and Virtual Disks that brings up a summary of of the disk groups. I have a disk group called 1 (RAID 5) (1.362TB), I expand that and there is a virtual disk called DATA (1.362TB). I want to add all that unconfigured space to the DATA virtual disk. How can I do that? Please use simple easy to follow instructions, as I haven't done this before.   EDIT: In the summary page I am looking at the total capacity and the available capacity is 1723.563 GB. I don't know where some of that space is coming from. How can I add it all to the DATA virtual disk?
