Mailbox Copy status Disconnected and Healthy

I am in the process of taking our Exchange environment from 2010 SP1 to SP3 RU5 (Build 123.4).  

I updated the CAS and HTs without issue.   Today I tried my first passive mailbox server and while the update completed successfully, I'm seeing a handful of database copies set to 'Disconnected and Healthy' copy status.  

Rebooting the server did nothing to alleviate the situation, and I've tried suspending the database and waiting a few minutes before Resuming but after a refresh or two it will revert to 'Healthy and Disconnected' status.    Even more disconcerting, refreshing the Database Copies tab for that mailbox server shows that several of the DB's are bouncing around between healthy and the 'disconnected and healthy' state.  

At this point, I'm not sure if it's worth it to reseed the passive copy through the EMC.  Database sizes range from 20-50 GB for the mailboxes, but our archive databases are ridiculously large with most being easily 150GB.  

So, I suppose my question is ... what would be the best route?   I have no problem removing the passive database copy and re adding it, but if it fails that opens a completely DIFFERENT problem.

Thoughts?

Hello,

150GB is actually pretty small buy most standards. I have databases approaching 1TB. You will likely need to reseed the databases. Try one of the 20GB ones and see if reseeding fixes the problem before you reseed the larger ones.

I'm reseeding and it's going OK.   I had one error, probably on my side, where I let a smaller database kick off the reseed before crashing for the night.  I woke up the next morning and it was in a finished state (meaning, I needed to click the finish button) but the MMC had timed out and wanted to shut down.  I shut down the MMC and EMC and brought it back up, but was unable to suspend any thing do to RPC communication errors.  I had to bounce the server to get everything straight again, and now I'm humming along.

Is there any gain from reseeding versus just removing the database from the Passive and adding it back as a database copy?

Reseeding and removing and adding the copy back in are essentially the same operation. A reseeding would take fewer commands to execute.
