RAID Drive Missing After OS Restore

I have a ProLiant DL360 with a P440ar RAID controller. I had to restore the server from an image backup and now Windows Server 2012 doesn't recognize one of the 600GB drives in the RAID5.

I don't have any errors or bad light status on the drives and when I check them in the raid manager all physical and logical drives are accounted for. I noticed I do have one of the RAID 5 drives plugged into port 2 on the controller whereas all the other drives are on port 1. There were no changes to the RAID configuration but Windows is only showing 600GB available for the logical drive (which should be around 1200GB.)

Re: RAID Drive Missing After OS Restore

I figured it out and it was size descrepency between what Windows was seeing and diskpart was seeing. I was able to open the volume in diskpart and ran 'extend filesystem' and poof.
