Types of alerts

VCS generates the following types of alerts.

Managing alerts

Alerts require user intervention. You can respond to an alert in the following ways:

An administrative alert will continue to live if none of the above actions are performed and the VCS engine (HAD) is running on at least one node in the cluster. If HAD is not running on any node in the cluster, the administrative alert is lost.

Actions associated with alerts

This section describes the actions you can perform on the following types of alerts:

Negating events

VCS deletes a CFAULT alert when the faulted cluster goes back to the running state

VCS deletes the GNOFAILA and GNOFAIL alerts in response to the following events:

Concurrency violation at startup

VCS may report a concurrency violation when you add a cluster to the ClusterList of the service group. A concurrency violation means that the service group is online on two nodes simultaneously.

Recommended Action: Verify the state of the service group in each cluster before making the service group global.
