[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings.

The Microsoft Exchange Analyzer Tool determines whether Local Continuous Replication (LCR) is enabled. If LCR is enabled, Exchange Analyzer determines the location of each passive database copy to verify that it is not located on the same physical hard disk as the active database copy. If the active and passive copies of a database are on the same physical disk, you receive the following warning message:


Local Continuous Replication (LCR) files Location

Local Continuous Replication (LCR) is enabled for storage group Storage_Group_Name on server Server_Name, but the LCR database is placed on the same physical disk as the running database.

To address this warning, move the passive database copy to a physical hard disk that does not host the active database copy.
