If you already have a CommServe server that you want to use as the production CommServe host, then you must install only the CommServe Failover package.
Before You Begin
-
Make sure that the CommServe is installed before installing the CommServe Failover package.
-
Download the Commvault software installation packages. For more information on how to download the software, see Download the Commvault Software.
-
Make sure that the bAllowMultiInstances registry key does NOT exist in the CommServe. You can verify whether the key exists using the Windows Registry Editor in the HKEY_LOCAL_MACHINE\SOFTWARE\GalaxyInstallerFlags\ bAllowMultiInstances folder. (Make sure to delete the key if it exists.)
