VCEM Profile Failover and Profile Moves

Initiating Failover using HP SIM Automatic Event Handling
This section describes how to configure and use HP SIM’s Automatic Event Handling for
notification and to automatically initiate failover.
Concepts
The following items need to be configured for Automatic Event Handling to initiate failover:
• The events that you want to trigger failover are selected. Below HP recommends a set of
events for you to consider. You may use these events or select your own. The selected
events are placed into an HP SIM event collection.
• In HP SIM an “action-on-event” task is created. In creating this task the failover event
collection is applied to a collection of managed systems. One or more actions are
configured to execute whenever any event in the collection occurs. These actions include e-
mail notification and execution of a custom tool. VCEM provides HP SIM custom tools to
initiate failover. These custom tools use either the host name or ip address of the system
that posted the failover event, as the argument to the VCEM failover CLI command. One of
these custom tools is selected and configured with the action-on-event.
This procedure for configuring Automatic Event Handling is described in detail below.
The following figure depicts how the automatic initiation of failover works once configured.
Figure 3. Automatic initiation of Profile Failover using HP SIM Automatic Event Handling
In the Figure 3 above:
• HP SIM events originate on the managed systems and are posted to HP SIM via Ethernet.
•
HP SIM processes the events and recognizes the selected failover events.
•
On the first occurrence of any failover event, HP SIM runs the custom tool. (Note: it is
possible to modify the “first occurrence” behavior through user-provided scripting, see
below.)
