VCEM Profile Failover and Profile Moves White Paper

Figure 5: Automatic initiation of profile failover using HP SIM Automatic Event Handling
In Figure 5 above:
• HP Systems Insight Manager events originate from the managed systems and are posted to
HP Systems Insight Manager via Ethernet.
•
HP Systems Insight Manager processes the events and acts on the selected failover events.
•
On the first occurrence of any failover event, HP Systems Insight Manager runs the custom
tool.
Note: It is possible to modify the “first occurrence” behavior through user-provided
scripting, as described below.
For more information, see Configuring HP Systems Insight
Manager Action on Events script to initiate failover
•
The custom tool invokes the VCEM failover command and passes either the host name or
IP address of the system that posted the failover event.
• The host name or IP address is mapped to its enclosure and bay location.
• A failover job is started for that enclosure and bay.
• The failover job runs as described above. Communicating via Ethernet with the VC
interconnects for the enclosures containing the source and spare bays, the job moves the
server profile from the source to the spare bay and then powers on the spare server.
Choosing HP Systems Insight Manager Events for failover
You must select the HP Systems Insight Manager events you wish to use to initiate failover.
HP has recommended a collection of events for your consideration. These recommendations
are listed after several practical topics on using events to automatically initiate Failover. See
How HP selected the set of installed failover events for more information.
