Verifying Hardware Event Monitoring

Once you have created the monitoring requests you need for your system, you may want to verify that they are working as you expect. The most effective way of verifying hardware event monitoring is to simulate a hardware failure or event. Depending on the hardware, you can do this by removing a disk from an array, unplugging a cable, turning off the hardware resource, using known defective media, etc.

The simulated fault should generate event messages using all the notification methods you have specified. If it does not, check the monitoring requests and make sure they are configured properly.
