exchange 2010 DAG problem

Two Exchange server, EX01 & EX02 are running in DAG. Mail copy on EX02 was failed but I can't resume it .

I have already tried
1. Update the database copy through GUI
2. Resume the database through GUI
3.  I have also tried to delete the current database and add it back to EX02 again.

None of the above can fix my problem. Below are some further information. Any further advise ? Tks

I didn't say that.
What I said was to stop using it and follow the instructions I have give you - which is to remove the database copy completely, rather than trying to use the update command to do it for you. For whatever reason it isn't working correctly.

If there is no backup running at the moment, then you should probably force one to run.
Are you using the native backup or a third party tool to do the backup?

To be clear - you have attempted to remove the copy of the database?
When you did that, what happened? It is obvious the databases have got in a mess, so you need to get down to a single copy, then clean up and add them back to the DAG.

Current database copy on EX02 (standby) is shown below. Can you guide me how to fix the problem ?  The clean copy is on EX01 and I have tried the following command but it doesn't help.,  Great Tks

Does it cause the a "BackupinProgress" flag on the source database on EX01 that I need to explicitly clear before issuing the command ? Tks

Stop trying to use the update commands - those aren't going to work.
Actually remove the copy - by clicking on the copy and choose remove.
Then on the server itself, clean up the files by deleting the database and logs.

Do you have a backup running on the database at the moment? If you do, let it finish. If not, force one to run before you do anything else.

No backup is runnint currently.

Do you mean the update-command no longer supported in Exchange 2010 ?
