102 NetIQ eDirectory 8.8 SP8 Installation Guide
Where <sharedfilesystem> is the cluster shared storage. The path of the <sharedfilesystem>
should be same as the path location specified when the primary node was configured.
The nds-cluster-config utility links the secondary cluster node to the shared eDirectory data
located on the shared cluster file system.
19 Start eDirectory services by running the following command:
ndsmanage startall
Verify the status of eDirectory by using the ndsstat command.
20 Stop eDirectory services on the secondary node by running the ndsmanage stopall command.
21 After successfully configuring eDirectory on both nodes of the cluster, you must also change the
startup mode of the ndsd service on each node by using the following command:
chkconfig -d ndsd
22 After the configuration utility finishes configuring the secondary node, you can use the cluster
manager to add the eDirectory services in the cluster.
IMPORTANT: Ideally, the cluster manager checks that the same DIB is not accessed by two or more
nodes simultaneously. However, you must ensure that ndsd does not run from two or more cluster
nodes simultaneously. This is because accessing the same DIB through two or more nodes leads to
DIB corruption.
10.1.3 Configuring SNMP Server in Clustered Linux Environments
1 On all the nodes, modify the snmpd.conf file. For more information, see “Installing and
Configuring SNMP Services for eDirectory” in the NetIQ eDirectory 8.8 SP8 Administration Guide.
2 Start ndssnmpsa.
3 Select Yes as the Remember password option.
4 To start the snmp service, perform either of the following:
 Add
/etc/init.d/ndssnmpsa start to the post_ndsd_start script and /etc/init.d/
ndssnmpsa stop
to the pre_ndsd_stop script.
 Add
ndssnmpsa as a cluster resource with a dependency on eDirectory resource.
NOTE: Because eDirectory is listening on a virtual IP address, traps have the IP address of the host,
which is the Agent IP address.
