Creating Disk Monitoring Requests
There are two ways to create HA Disk Monitor requests:
• From EMS GUI, to send alerts to HP OpenView ITO, Network Node
Manager, email addresses, the console, a textlog file, or the system
log.
• From ServiceGuard, to configure any HA Disk Monitor resource as a
package dependency.
These requests are not exclusive. You can configure the HA Disk Monitor
from both ServiceGuard and EMS. If you are using EMS to monitor disks
for ServiceGuard package dependencies, it is recommended you also
configure EMS to send events to alert you when something threatens
data or application availability.
NOTE When ServiceGuard packages are configured, the package configuration
(including package dependencies) is automatically distributed to all
nodes in the cluster. If you also want to send event notification to your
system monitoring software (IT/O), you must configure the same
monitoring requests on all nodes in the cluster using the EMS GUI.
The following sections take some common disk configurations in a high
availability environment and give examples of the types of monitor
requests you might want to create.
