Novell Cluster Services can automatically send out email messages for certain cluster events like cluster and resource state changes or nodes joining or leaving the cluster. The subject line provides information about the cluster name, resource name, action taken, and node name. For example:
CL1: POOL1_SERVER online on NODE1
IMPORTANT:Novell Cluster Services uses Postfix to send email alerts. If you have a cluster resource that uses SMTP, that resource might not work in the cluster unless you change the Postfix configuration.
For example, GroupWise uses SMTP and will not function as a cluster resource if Postfix uses the same port, which it does by default. In this case, Postfix must be configured to use a different port. You can do this by editing the /etc/postfix/main.cf file and changing the values for the inet_interfaces, mydestination, and mynetworks_style lines.
You also need to change the listen port for the smtpd process in the /etc/postfix/master.cf file. See the Postfix Web site for more information on configuring Postfix.
You can enable or disable email notification for the cluster and specify up to eight administrator email addresses for cluster notification.
In iManager, select , then select .
Specify the cluster name, or browse and select the Cluster object.
Click the button under the cluster name.
Click the tab.
Under , select or deselect the check box to enable or disable email notification.
If you enable email notification, add up to eight email addresses in the field provided.
You can click the buttons next to the field to add, delete, or edit email addresses. Repeat this process for each email address you want on the notification list.
If you enable email notification, specify the type of cluster events you want administrators to receive messages for.
Only Critical Events: (Default) Select this option to receive notification only of critical events like a node failure or a resource going comatose.
Verbose Messages: Select this option to receive notification of all cluster state changes including critical events, resource state changes, and nodes joining and leaving the cluster.
If you enable email notification, specify whether you want to receive notification of all cluster state changes in XML format by selecting the option.
XML is selected by default. XML format messages can be interpreted and formatted with a parser that lets you customize the message information for your specific needs.
