17.3.2 Configuring the Monitor Agent Cluster Resource to
Load and Unload the Monitor Agent
The properties of the Monitor Agent Cluster Resource object define how the Monitor Agent
functions within the cluster, how the Monitor Agent is loaded and unloaded, and how failover and
failback situations are handled. Complete the following tasks for the Monitor Agent cluster
resource:
"Modifying the Cluster Resource Load Script for the Monitor Agent" on page 207
"Modifying the Cluster Resource Unload Script for the Monitor Agent" on page 209
"Setting the Failover List and Policies for the Monitor Agent" on page 210
Modifying the Cluster Resource Load Script for the Monitor Agent
The cluster resource load script executes whenever the Monitor Agent cluster resource comes
online.
To set up the load script in iManager:
1 Expand Clusters, then click Cluster Options.
2 In the Cluster field, browse to the Cluster object where the Monitor Agent cluster resource is
located.
3 Click the Cluster object to display the cluster resources that belong to the cluster.
4 Select the Monitor Agent cluster resource that you created when you set up the
partition, then click Properties.
The default load script from a generic IP service template appears as follows:
#!/bin/bash
. /opt/novell/ncs/lib/ncsfuncs
# mount the file system
exit_on_error mount -t reiserfs /dev/evms/vol /mnt/generic
# add the IP address
exit_on_error add_secondary_ipaddress a.b.c.d
# start the service
exit_on_error /etc/init.d/myservice start
# return status
exit 0
