Deploying eDirectory on High Availability Clusters 105
10.3 Troubleshooting Clustered Environments
10.3.1 Repairing or Upgrading eDirectory on Clustered Nodes
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.
10.3.2 Creating Windows Registry Keys
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:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NDS Server0\ImagePath
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.
10.4 Configuration Utility Options
The options available for use in the configuration utility are as follows:
<configuration utility> [-h] [-u] [-s /<sharedfilesystem>]
Where <configuration utility> is either nds-cluster-config or dsclusterconfig.exe ,
depending on the platform, and
<sharedfilesystem> is the location you want to use for the
eDirectory shared cluster data.
Parameter Description
-h
Displays the configuration utility help.
-s
Specifies the shared directory path for the cluster.
-u
Enables the utility to configure eDirectory on the
cluster in unattended mode.
If you run the utility by using the
-u option, you must
also use the
-s option and specify the shared directory
path. For example:
nds-cluster-config -u -s
<sharedfilesystem>
