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 Storage Mirroring Recover 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 = 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 =
selected).
Note:
If you are using Active Directory, you should enable this option. Otherwise, you
may experience problems with failover.
Advanced settings
The following options allow you to control what functions Application Manager will
perform during configuration. By default, Application Manager performs all of these
functions. Individual functions should only be disabled for testing or debugging
purposes.
Note:
These options are only available when you launch Application Manager using
the command line /sharepoint /advanced option (dtam /sharepoint /advanced).
