Storage Mirroring High availability for Exchange Server 2000/2003 application notes 7
6. When you installed Exchange on the source, the default Exchange storage group was assigned E00
as the prefix of the log files. The second storage group was assigned E01, the third E02, and so on.
The storage groups on the target must have the same numbering scheme. If you have one or two
storage groups on your source, you can continue with the next step. If you have more than two storage
groups on your source, verify that the prefix numbering is the same on the source and target.
a. Using Exchange System Manager on the source, select the source Exchange server. Right-click each
storage group and select Properties. Record the prefix number assigned to each storage group.
b. On the target, use Exchange System Manager to verify the prefix number assigned to each storage
group.
If the storage group prefix numbers are identical, you can continue with the next step. If the storage
group prefix numbers are different, you will need to modify them. You can do this by deleting the
storage groups and re-creating them in the same order they were created on the source, or you can
use ADSIEdit to modify the prefix numbers. Using ADSIEdit, modify the properties of the entry noted
below to change the msExchESEParamBaseName on the Properties page to match that of the
source. The entry that must be edited is
CN=First_Storage_Group_Name, CN=Information Store,
CN=Exchange_Server_Name, CN=Servers,
CN=First_Administrative_Group_Name, CN=Administrative Groups,
CN=Exchange_Organizational_Name, CN=Microsoft Exchange, CN=Services,
CN=Configuration, DC=Domain_name, DC=com
You will have to use ADSIEdit from the Windows Support Tools to make this change. See your
Windows reference guide for more information.
7. Install Storage Mirroring on the target and reboot when the installation is complete. This will initialize
Storage Mirroring and stop the Exchange services because the services are set to manual.
8. Run the setup.exe file to install the Exchange Failover utility in the Storage Mirroring directory on the
target.
