VCS provides a method for notifying important events such as resource or system faults to administrators or designated recipients. VCS includes a notifier component, which consists of the notifier process and the hanotify utility.
VCS support SNMP consoles that can use an SNMP V2 MIB.
The notifier process performs the following tasks:
If you have configured owners for resources, groups, or for the cluster, VCS also notifies owners of events that affect their resources. A resource owner is notified of resource-related events, a group owner of group-related events, and so on.
See "VCS Attributes" for descriptions of the attributes that define owners for cluster objects.
There are four severity levels: SevereError, Error, Warning, and Information. SevereError indicates the highest severity level, Information the lowest. Note that these severity levels are case-sensitive.

SNMP traps are forwarded to the SNMP console. Typically, traps are predefined for events such as service group or resource faults. You can use the hanotify utility to send additional traps.
