Hi,
You have two virtual disks using the same set of drives correct? Most likely that is the problem, we don’t recommend doing that for this reason, it makes it so reconstruct may not work. You can try updating the firmware on the drives and controller and see if the option shows up. Also is the replacement drive a Dell drive?

Hi Josh,

Ty for the reply. To be honest, I have no idea if I have two virtual disks using the same set of drives. How can I check that? I did not set any of this up, so coming into it without any knowledge, sorry. Also, how do I update the firmware on the drives and controller? I at least know it is using a PERC H700 controller. Three of the four drives are certified Dell drives, whereas the 4th is not. It came from a 3rd party of Dell's. 

If you don’t have OMSA installed you can install it and look at the virtual disk settings, if you post screenshots, we can figure out the configuration. https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=24H24

Josh,

I do have OMSA installed. I have attached two screen shots. One of our virtual disks, and the other of our physical disks. 

Along with the screenshots below, I wanted to add some more information to see if anyone could help. 

We are running a Dell Power Vault nx300 with a PERC H700. We have two virtual disks, one being used for OS I think at 80 GB (I did not set it up), and the other at 1.78 TB being used for data. I simply want to add the 4th drive, rebuild, and be able to expand the data drive to an additional TB making it about 2.8 TB. I have updated the firmware on the PERC from the dell site, and updated to the latest OMSA I could. 

The issue is, after putting in the 4th disk, it is in a ready/spun up state, but rebuilding is not an option when I go into the configuration hitting control R. I can assign it as a global hot spare, and it just goes into hot spare status, rebuild does not take affect. I have rebooted the server, removed the drive numerous times. I have also ensured the latest windows updates have been applied to my Windows 2008 R2 Storage Server Standard OS.

The screen shots in my previous post also apply to this if anyone can help I would be extremely grateful. Thank you. 

The Yellow yield sign says "Status - Non-Critical" when I hover over it. The disk is non-Dell certified, revision #, FW # are difference than the other 3 disks I have. Would that cause the issue?

If you can try another drive that would be best. It could be the slot, but that is less likely to be the issue.

I would try updating the H700 firmware and see if it will let you use the non-Dell drive. https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=2948G

Josh,

I performed an update this past weekend, and I believe this is the PERC FW version in use. Is there a way I can check using OMSA?

Josh,

Verified, the latest FW driver is installed. As mentioned before, this 4th disk is different than the previous 3 which were all dell certified disks of the same type/revision/FW/SN# etc. The 4th disk is a diff revision/FW/Product# etc. I have rebooted the server, taken the disk out with it powered all the way back down, re-inserted it, and it has a green light, is in online status and spun up, but I cannot reconfigure from OMSA or rebuild from the PERC Menu upon booting up and hitting cntrl-R. The reconfigure option within Vdisk menu in OMSA is not there, and rebuild is totally grayed out in the PERC menu using Cntrl-R. 

Any other suggestions?
