Recover exchange 2010 edb

I have a dag group for one edb in two servers.

Server A is under failed and suspended mode. Server B is under dismount mode. When I tried to mount the edb, the server displayed error message about log file corrupted.

I checked the E00006E009C.log file exist in Server B but not in Server A. Moreover, the edb header in Server A is dirty shutdown and Server B is clean shutdown.

What recover procedures that I need to do?

It is exchange server 2010.

Thanks
