When the VCS engine starts up, it queues all messages as Information. However, when notifier connects, it communicates one of the following severity levels to HAD, depending on which is the lowest:
If notifier is started from the command line without specifying a severity level for the SNMP console or SMTP recipients, notifier communicates the default severity level Warning to HAD. If notifier is configured under VCS control, severity must be specified. See the description of the NotifierMngr agent in the Veritas Cluster Server Bundled Agents Reference Guide.
For example, if the following severities are specified for notifier:
Notifier communicates the minimum severity, Warning, to HAD, which then queues all messages labelled severity level Warning and greater.
Notifier ensures recipients gets only the messages they are designated to receive (according to the specified severity level). However, until notifier communicates the specifications to HAD, HAD stores all messages, because it does not know the severity the user has specified. This behavior prevents messages from being lost between the time HAD stores them and notifier communicates the specifications to HAD.
