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.
