I have couple of databases in my exchnage 2007 CCR.

Now only one database is dismounted. I restarted one server still no luck.
I tried in both the servers but it is dismounted in both servers.

When I open cluster managemnt console
I can see all database online but this database is "online -pending"

Your urgent help is highly appreciated.

What is the worst case scenario to rebuild the database

Check If the database has been shut down correctly(clean shutdown),  If the database has not been shut down correctly(dirty shutdown). You may need to restore the database with the backup. Or you need to do a database repair.

Once that done, please move the Checkpoint file and all Log files to a different folder and try to mount database again.
Regarding how to remove the log files, you can refer to the following article:

Step 1st ---- You need to check  the database is clean shutdown or not.

for that

eseutil /mh "database path" if the database is cleanshutdown you are safe just remove the log file for that particular SG.

follow Mahesh articles all the steps are there.

Hello Abbsift,

Check if the databases are in a dirty shutdown state?

Open a command prompt and do the following...
Navigate to the directory where you EDB database is located...

eseutil /mh <databasename.edb>

Look for "State" if it is Dirty Shutdown then you will need to repair this database before you can bring it back online (mount).

If the shutdown is Dirty do the following...

eseutil /r /l <databaseLogs> /d <database edb location>

If using the /r switch does not work you can then use the /p switch will usually get it to a clean shutdown state.

eseutil /p <DatabaseName>

Once you have done this you can then check the state again using the eseutil /mh <databasename.edb>

Once the state is a "clean shutdown state" you can then re-mount the database to Exchange.


Thanks
Colin Paul

This is what Microsoft did.

1. Ran the eseutil /mh <databasename.edb> and found problematic database is not  in clean shutdown state

2. Ran command eseutil /r /l <databaseLogs> /d <database edb location>.
   The database mounted after this.

3. They reseeded the database

Finally they said there was connectivity problem between servers.
That was the reason for the problem.
But I could not find any connectivity problem.
