H710 Blocked Drive Issue | T420 | Nothing Changed

Hey all,

A little bit on what I have already tried today:  I have a PowerEdge T420.  Nothing has changed with the config and the H710 has the current firmware version.  Our BIOS firmware was 1 back, so I just upgraded it to 2.7.0 to see if it corrected the issue and it didn't.

I have a RAID1 w/ 2 Dell branded Seagate Savvio 10k drives functioning as the system/boot partition for our Hyper-V host.  Part #: 9FK066-150.  Server 2016 installed.

I then have 4 other drives that work as a RAID10 that host my actual VMs.  The server and office location is 100% down right now because one of the RAID1 drives listed above crashed.  Usually it wouldn't be a problem - but it has put the second drive in the RAID1 array into "blocked" for some reason.

2 Fold Question -

1) How can I get the one function RAID1 drive up so I can at least get them up over the holiday weekend here.

OR

2) I have never had to rebuild a Hyper-V host because of failure, just for upgrading.  Theoretically I should just be able to replace both drives with like spares I have on the shelf and then build the RAID1 array back up with Server 2019 w/ Hyper-V roles and the config and VHDs are still okay over on the RAID10 array.  I do have 2 600GB Dell drives in a newer server I just bought I would be willing to go this route if it would be easier.

Any information/help is MUCH appreciated!  Thank you.
