HP OpenView Storage Mirroring High Availability for Exchange Server 2000/2003 Application Notes (May 2005, T2558-88020)

NOTE: If you start Exchange Server and mount the replicated databases on the target, or if the data on

the target is otherwise modified, the data on the source and target will no longer match. If the updated

data on the target is not needed, perform a full or difference with block checksum mirror from the source to

the target. If the updated data on the target is needed, restore the data from the target to the source.

Updating Exchange components after the initial

configuration

After you have completed the initial configuration and Storage Mirroring is mirroring, replicating, and

monitoring for a failure, your Exchange components on the source may not be static. You may need to

add a new information store to your Exchange configuration, or you may need to update to a new

Exchange service pack. In these cases, you do not need to repeat the entire initial configuration. Use the

appropriate instructions below, depending on the change you need to make.

Adding a new information store

1. Pause transmission from the source to the target so that you can start Exchange on the target. From the

Storage Mirroring Management Console on the source, right-click the established connection and

select Transmit, Pause.

2. Start the Exchange services relevant to your environment on the target.

3. Create the information store on the target with the same name and location that will be created on the

source.

4. Stop all of the Exchange services on the target that you started.

5. Back on the source, resume transmission by right-clicking the paused connection and selecting

Transmit, Resume.

6. Create the information store on the source with the same name and location that were created on the

target.

NOTE: If you selected a path that is outside of the existing replication set, you will need to modify the

replication sets on the source and target to include the path(s) to the new data.

7. Again using the Storage Mirroring Management Console on the source, check the orphan settings for

the established connection. Right-click the connection and select Connection Manager.

8. Select the Orphans tab and verify that you are either moving or deleting orphan files. For more

information on orphan files, see the HP OpenView Storage Mirroring user’s guide. Click OK to close

the Connection Manager.

9. Perform a file differences block checksum mirror by right-clicking on the connection and selecting

Mirroring, Start.

10.Select File differences and Use block checksum and click OK.

When the difference mirror is complete, the target will be ready to stand in for the source with the new

information store.
