files on the master node of the cluster.
9.2.2 Creating a Resource Template
Templates help ensure that all of the necessary definition information, dependent services to be
loaded and unloaded, and the shared service or storage are entered correctly when you are
configuring multiple servers and clusters. You can use the default templates as a guide for what
types of information to include in your personalized template.
1
Start your Internet browser and enter the URL for iManager.
The URL is http://
server_ip_address
/nps/imanager.html. Replace
server_ip_address
with the
IP address or DNS name of an server in the cluster that has iManager installed.

If desired, in
Inherit from Template
, browse to the Cluster object and select the existing
resource template in the Cluster container that you want to personalize for the new template.
9
Ensure that the
Define Additional Properties
check box is selected, then click
Next
to continue
to the Load Script page.
10
On the Load Script page, configure the load script for the cluster resource template.
10a
Edit or add variables with example values for your template configuration, such as the
mount point, IP address, container name, file system type, and device.
10b
Edit or add any lines to the load script that are required to load dependent services such as
Web servers or file access protocols.
10c
Edit or add the necessary commands to the script to load the resource on the server.
For example, this might include bind command for the NCP
TM
service and the mount
commands for the shared disks and file systems.
10d
Specify the default
Load Script Timeout
value, then click
Next
to continue to the Unload
Script page.
The timeout value determines how much time the script is given to complete. If the script
does not complete within the specified time, the resource becomes comatose. Cluster
Services marks the process as failed right after the defined timeout expires, but it must
wait for the process to conclude before it can start other resource operations.
