You don't need to define any path for DB's. For setting up DAG, you need following,<br />
<br />
1) DAG Name and IP<br />
2) Same drive structure, example you have 2 servers, ServerA and ServerB and you planned to implement the DAG.<br />
3) Mapi NIC and Heart Beat NIC both with different Subnet class

quick question for the experts...after DAG is created and when adding a copy of a database (passive copy) to another mailbox server I am not prompted by the wizard for the database location, just the server name. &nbsp;Do I then need to move the database to the desired drive/location or will it automatically create itself on the same drive/file path as the active database? &nbsp;For example, it on server1 the database is on the F drive in a folder called DB, will it auto create itself on Server2 in the F drive in a folder called DB, or will I have to move it to there? &nbsp;Thanks.
