Any change you make to the script in the editor will be copied to the appropriate server when
configuration changes are accepted, thus overwriting any changes that have been made outside the
Application Manager.
The scripts can be overwritten by certain operations during setup. For example, any changes to
configuration options done in the Application Manager will overwrite previous script changes. If you
want to make permanent changes to a script, you must modify the appropriate .txt file within
the Application Manager installation directory. If there is more than one client machine that will be
configuring failover, the change must be made to all the appropriate .txt files.
Before running Application Manager multiple times (for example, when re-enabling protection after a
failover/failback), save a copy of your post-restore and pre-failback batch files. After Application
Manager executes, replace the default script file(s) with the customized file(s) that you saved.
Items to failover
Select the items to failover.
1. Select the Server Name checkbox if you want the source name to be added to the target when
failover occurs (Default = NOT selected).
2. Select the Shares checkbox if you want the source file shares to be added to the target when
failover occurs (Default = NOT selected).
3. Select the Active Directory Hostname (SPNs) checkbox if you want to remove the host SPN
(Service Principle Name) automatically from Active Directory for the source and add it to Active
Directory for the target during failover (Default = NOT selected).
NOTE: If you are using Active Directory, you should enable this option. Otherwise, you may
experience problems with failover.
