I have 4 servers in a DAG and each DB has three copies one active and two passive. One passive copy in a save data center and other passive in a remote data center.

Exchange 2010 Servers

Now the 3rd copy which is on the remote DC has weird volume configuration, although the Volume drive name is same i.e.  P Drive but this P drive is Dynamic and has multiple volume within that volume.

I want to setup a new disk as basic disk and just create a one single volume and then configure the DB folder by folder like other server.

Now the steps I am looking for?

#1 - suspend the copy on this server

#2- change the drive letter from P to Z

#3 - Present the disk to the server and then create a new Volume with the same drive letter P

#4 Copy the database files from old volume P or Z to the new P Volume

#5 Resume the database copy

Hi 

First suspend the replication Suspend-Replication , stop msexchangesearch service, dismount DB's, add the drive letter as same in other servers, move database path, mount the DB's and resume the replication

Below is an example for moving the DB

Example:
Move-DatabasePath -Id Database01 -EdbFilePath "S:\Databases\Database01\Database01.edb" -LogFolderPath "T:\Databases\Database01" -ConfigurationOnly.

#2- change the drive letter from P to Z - For this point you need to make sure the below point 

All copies of a database use the same path on each server containing a copy. The database and log file paths for a database copy on each Mailbox server must not conflict with any other database paths.
Or you will need to  create DB and log paths using mountpoints and make to look path similar like other servers else it will not work,

I would also recommend suspending the replication to the copies on this server before putting it into maintenance mode and then resume once the activity is done
