Configuring LifeKeeper Event Email Notification
Prerequisites
The Event Email Notification feature is included as part of the LifeKeeper core functionality and does
not require additional LifeKeeper packages to be installed. It does require that email software be
installed and configured on each LifeKeeper node that will generate email notification of LifeKeeper
events. LifeKeeper uses the mail utility, usually installed by the mailx package to send notifications.
The configuration of email is beyond the scope of this LifeKeeper feature. By default, LifeKeeper
Event Email Notification is disabled.
Configuration Tasks
The following tasks must be performed to set up LifeKeeper Event Email Notification.
1. Ensure that the mail utility is available as noted above.
2. Identify the user or users that will receive email notices of LifeKeeper events and set LK_
NOTIFY_ALIAS in the LifeKeeper defaults file /etc/default/LifeKeeper. This can be
done either from the command line or by editing the file /etc/default/LifeKeeper and
specifying the email address or alias or the list of email addresses or aliases that should
receive notification.
l From the command line, use the lk_confignotifyalias utility (see the lk_
confignotifyalias(1M)man page for details). This utility will only accept email
addresses or aliases separated by commas.
l Or, edit the defaults file /etc/default/LifeKeeper to add the email address or
alias. Search for the entry LK_NOTIFY_ALIAS= and insert the email address or alias
(single or list separated by commas) to the right of the = (no white space around the =).
Verifying the Configuration
To verify that the configuration is working, initiate a LifeKeeper action (for example, start or stop
LifeKeeper or bring a resource in-service manually using the LifeKeeper GUI). Verify that an email
message was received by the users specified in LK_NOTIFY_ALIAS in the file
/etc/default/LifeKeeper and a message was logged in the LifeKeeper log file.If an email
message has not been received, follow your normal debugging procedures for email failures.The
