Using EMS HA Monitors

50 Chapter 2
Monitoring Disk Resources
Creating Disk Monitoring Requests
Assume you have a great need to know the status of your system at all times. You
would need a short polling interval, perhaps between 30 and 120 seconds. (If you
notice the disk monitor consumes too much CPU, you may want to set a longer
polling interval.) Assume also that you want an Initial event sent to make sure the
request is configured properly. You would want to set the Return option to send an
event when disks come back up. You would configure the events to use opcmsg
(ITO) protocol because you use HP OpenView IT/Operations as your system
management tool. The parameters for your monitoring request would look like
Figure 2-3.

When Disks Fail
All requests are created in a similar way. You need to make sure you perform these
steps for all instances in all volume groups you want to monitor.
