Having problems creating a Mirrored Volume

I’m trying to make two disk drives, H (Disk 4) and G (Disk 5), into a mirrored volume. The two drives are both Seagate 5 TB drives. They have been previously used, then wiped clean of all previous data. They are shown in Disk Management as Basic, 4657.40 GB, and Online. Each is formatted as NTFS and shown as Healthy (Basic Data Partition). Here's what I see in Disk Management:







When I right click on Disk 4, I get a popup window with a few options, but the only significant option is Convert to Dynamic Disk. New Mirrored Volume is greyed out.





I’ve been following several guides I found on the internet, all of which gives the same basic steps. However, those steps don’t produce the same outcome as what I’m seeing.

Do I need to make these into Dynamic Disks first, then attempt to create the mirrored volume? What is the consequence of creating a Dynamic Disk from a drive with an assigned drive letter?

My eventual goal is to create a mirror for my Photo Archive (J drive that has 3.5 TB of photos and other data. I would like to mirror this drive onto either the H: or G: drives. I don't want to attempt this until I'm able to get the process for a basic mirror figured out. My J: drive is just slightly larger than either of the other two drives so I'm presuming that I will need to shrink the J: drive partition a little bit so that it is just smaller than the other drive that will mirror the data.

Your insight will be greatly appreciated.

Create a Mirroring for existing volume(say F: drive)

Create a Mirroring for existing volume(say F: drive) using powershell storagespace and after completion of mirroring remove the initial disk that was used by F drive(i.e remove mirroring)

I have tried with diskpart and Disk Management Tool, these are interactive tools. i wanted to do it with simple commands in powershell

 

Disk mirror failed redundancy: Remove mirror or reactivate volume?

Hi,



Thank you for writing to Microsoft Community Forums.



The cause for Failed Redundancy would be that half, but not both halves, of a mirrored volume was imported. In Disk Management, the imported half of the mirrored volume receives Failed Redundancy status, while the disk that holds the
half of the mirror that was not imported receives Missing status. You can import the Missing disk at a later time to restore redundancy.



The solution for Failed Redundancy is to move all disks that span this volume to the new computer at the same time, and then import all of the disks together.



The complete solution is giving in the section A mirrored volume's status is Data Not Redundant from
Troubleshooting Disk Management.



You may also refer the section A dynamic disk's status is Offline or Missing from the above article and try the troubleshooting steps.



If you are still facing any issues related to Mirroring, then I suggest you to post your query in
IT Pro TechNet forums, where we have support professionals who are well equipped with the knowledge on Hard Disk Mirroring.



Hope it helps.
