Forgive me for this, but I am not the admin, just filling in. Drive 0 and Drive 1 in my dell r710 were mirrors of eachother. Drive 0 had a warning (amber light) so I replaced the hard drive with a new drive. I assumed because these drives were mirrored that it would rebuild, nothing happened. I assume I missed a step. I tried to reseat the Drive 1 (probably my biggest mistake) because now the datastore is inactive...this makes sense to me actually.

What I want to know, how do I get back online? How can I reactivate this datastore? I presume my data is fine, but the datastore is inactive now. I need some help with this.

Can you confirm, that the DELL R710 RAID MIRROR 1 is valid!

Check the R710 storage controller BIOS at POST/BOOT

Rebooting and going into controller config (PERC), I see this

Controller 0
Disk Group 0
Physical Disks
Disk 0 is showing Rebuild
Disk 1 is showing Online

The entire group is showing as "Foreign".  Is there something I need to do or is it rebuilding?

Most likely missing part was to enter controller config and that initiated rebuild.

You could just power off, and remove Disk 1.

I wasn't sure what to do. In the end, I shut down the VM's that were running on other discs and rebooted. I went into PERC controller config and noticed the disc group I was concerned with said "Foreign". I rebooted again and this time noticed a message asking me if I wanted to import foreign config - logical question so I answered yes. That started the rebuild process. I then booted all the way into esxi, ran console, and checked for datastore presence. It found it and said it was mountable - I mounted it. Problem solved.
