Configuration Change Notification

Specifying an increase or decrease in the number of active cores (using the icapmodify command) causes a core configuration change. An email notification is sent to the system contact when a change occurs that affects the configuration of cores.

If you do not want an email notification to be sent when configuration changes are made, disable this feature by using the following command on HP-UX systems:

/usr/sbin/icapnotify -n off

Example 2-1shows a configuration change email notification the Instant Capacity software sends to the system contact. Note that if the operation is a deferred configuration change, “previous” and “current” show equal values; only the value for “Number of cores to be active after reboot” reflects the requested change.

Example 2-1 Configuration Change Notification email for Instant Capacity System (not vPar)
