7200 HD failed, new drive not seen, monpd service down

We had a cooling issue in our data center recently and one of our 7200s overheated and shut down. Once cooling was restored, the 7200 was brought back online though it only showed one of the two drives.

We received a replacement drive from third party support, but the new drive isn't "seen" by the 7200 either (ie. tmsh show sys raid disk) even after powering off, re-seating it and powering back up.

(no "HD2" in the list)

There is an alert about the service "monpd" being down. The service list shows "monpd down, waiting for mysql to release running semaphore." I wondering if this is why the drive isn't seen.

Listing the services, this is what we have:

Anyone know how to resolve the issue with monpd? Would that have anything to do with the drive not being recognized? We're in the process of migrating the last two services off the active/standby pair of 7200s so they can be decommissioned, just need to squeeze a little more time out of them.

Thanks!
