Unable to Mount Database - 6.Oct.2011 10:32:58 AM

Exchange newbie here. Having issues trying to mount newly created databases. Hoping someone can point me in the right direction. I'm on Exchange 2010 Enterprise SP1. I have a DAG with 4 servers running the databases. I have other databases mounted on the same DAG, but a few will not mount. Also, the ones that do mount say mounted, not healthy. It is quite possible that I rebooted the server(s) in an incorrect order/manner

One thing I notice as curious is that when I view the properties of the DAG, I do not see the 3rd server as I do with the other DAG under Operational Servers

Also getting an error (not every time) when I go to view the DAG properties. I've also noticed that the cluster service is off when I go to check (not all the time)

The error I get when I try to view the DAG props reads "an active manager operation failed cluster api getClusterQuorumResource failed with 0x46" when runing the command get-databaseAvailabilityGroup

A database status will show mounted on the server the database is active on and it will say healthy only on the passive copies!

What error do you get when you try to mount the database?

Thank you for your reply and information. The error when I try to mount the database reads...

Database 'GSC-EXCH-S1-DB04' can't be mounted on server 'GSC-EXCH1.synnex.org' due to a previous error: Failed to determine the mount status of the active database copy. Verify that the underlying cause of the error has been corrected before attempting to mount the database. The error can be ignored and the mount allowed if Mount-Database is reissued with the -Force switch.

I have tried using the -force switch through the command line with no luck

This error seems very generic. You may want to look into the application logs in event viewer and look for any errors generated at the time u tried to mount the database.

After more investigation I have found that once I kill Symantec Endpoint, all my issues go away. So I will start investigating from that standpoint. Thank you very much for your help!

Now...Any suggestions using Symantec Endpoint on an Exchange server? Symantec's website says it will automatically detect and set itself up for Exchange but apparently that is not so true.

Thanks again for your reply and help!

Check that the exclusions are properly set in the antivirus.
