While you perform a repair or upgrade on any of the cluster nodes, the other cluster nodes must be paused or on standby to ensure that automatic failover does not occur.
As part of the configuration process in clustered Windows environments, the configuration utility automatically creates a registry key, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NDS Server0\ImagePath, on the cluster shared file system. eDirectory needs the registry key in order to start the x86 NDS Server service on the cluster nodes.
If the utility cannot create the registry key and returns an error message during configuration, you must use the Registry Editor to manually create the registry key on all cluster nodes, even if the configuration utility appears to have successfully completed the configuration.
Create the following registry key on all nodes:
Assign the following value to the ImagePath key:
"<primarynodeinstallfolder>\NDS\ndsserv.exe" /DataDir="<sharedstorage>\Files" ds
Where <primarynodeinstallfolder> is the folder where you installed eDirectory on the primary node and <sharedstorage> is the path to the shared file system location.
