Install ESI for Windows Suite with the ESI Exchange HA Extension on each mailbox server. When you install the ESI Exchange HA Extension, the ESI Exchange HA Extension PowerShell Toolkit is also installed on the server.
During the ESI installation, you are prompted to enter an encryption key password. This password is used to create an encryption key for communications between the ESI Exchange HA Extensions running on the Exchange servers. For the ESI Exchange integration to work correctly, you must type the same password each time you install the ESI Exchange HA Extension on each Exchange server.
To install ESI and the extension:
Confirm that the server has .NET 4.0 set up as a Windows Service.
Locate and double-click the ESI.3.*.Setup.X64.exe file.
In the InstallShield Wizard, click Next.
When the EMC Software License Agreement appears, read and accept the license agreement and click Next.
In the Setup window, confirm that only the core setup, ESI PowerShell Toolkit, and the ESI Exchange HA (High Availability) Extension options are selected and click Next.
Note: Click Change to change the installable path to a drive other than the default drive.
When prompted, type a password for the encryption key and click Next.
Note: The same password is required for each extension installation on each Exchange mailbox server. If the password is incorrect, the storage system will not be available on that server for replication. You can use the Seed generator.exe program to change the password.
In the Ready to Install the Program window, click Install.
Note: The ESI installer attempts to add a firewall exception rule to enable Remote Volume Management on the host where ESI is being installed. The ESI installer also attempts to enable PS Remoting on the same host. If the installer encounters a problem during these steps, you are instructed to perform these steps manually after the installation is complete.
