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

NOTE: If you are upgrading from an earlier version of the Exchange Failover utility, you will need to do

the following:

• Compare the sample scripts to your failback and post-restore scripts and incorporate the new

commands (-nopublicfolders, -onlypublicfolders) into your scripts.

• Modify the failover and failback scripts to remove the NSISPN commands. This functionality has been

incorporated into the utility and is no longer necessary in the scripts. Leaving the commands in the

scripts will not cause any harm or failure in execution.

• Domain structure—The two Exchange servers must have the same root domain.

NOTE: If you are using a WAN environment (the source and target are on different subnets), see

”Appendix 1: WAN configuration” on page 21 for additional requirements and specific WAN

configuration steps.

Backing up your environment

Before beginning these procedures, make sure you have a current backup of your source and target. Also,

make sure you have a complete backup of Active Directory.

Environment verification

Before you use the Exchange Failover utility, complete the following tasks to verify that the environment is

properly set up.

1. With both Exchange servers online, use Active Directory Users and Computers to move an existing user

from the source to the target and then back to the original source.

2. Verify that you can create a new user on the target.

3. To verify connectivity, create an Outlook profile for the new user on a client machine and connect to

the target.

Protecting your exchange data

Protecting your Exchange data requires four separate procedures. You must complete each section before

your data will be protected.

• ”Preparing the source server” on page 5 includes the installation and preparation instructions for the

source.

• ”Preparing the target server” on page 6 installs software on the target and configures Exchange on the

target.

• ”Configuring Storage Mirroring mirroring and replication” on page 8 walks you through creating your

Storage Mirroring replication set and establishing the Storage Mirroring connection between your

source and target servers.

• ”Configuring failure monitoring” on page 9 establishes high availability by configuring Storage

Mirroring failure monitoring.
