HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

11 Managing Events and Alerts
Overview
The system tracks system events internally. Some of these events require action on the part of the
system administrator, so they trigger alerts that are displayed for the administrator. Events are logs
created by the system which allow you to view the day-to-day health of your system. Alerts are
generated by the system when a system event requires immediate operator action/attention.
Checking the Status of a System
The checkhealth command checks the status of a system hardware and software components,
and reports any issues. You can specify which components you want the checkhealth command
to examine or check all system components. For detailed information about checking system status
and the checkhealth command, see the HP 3PAR InForm OS Messages and Operator’s Guide.
• Use the checkhealth command to view a status summary of all system components.
• Use the checkhealth -list command to view a list of all system components.
• To check the health of specific hardware and software components, issue the checkhealth
<component> command, where:
◦ <component> is the component, or list of components, you want to check.
Monitoring and Managing Alerts
Alerts are system events that require your immediate attention. An alert may be triggered by a
single event, a combination of events, or by repeated occurrences of the same event. The system
administrator is responsible for responding to alerts. For detailed information about alerts, see the
HP 3PAR InForm OS Messages and Operator’s Guide.
Viewing Alerts
• To display system alerts, issue the showalert command.
You can additionally display alerts by type (fixed alerts, acknowledged alerts, etc.). Refer to
the HP 3PAR InForm OS Command Line Interface Reference for information about alert display
options.
Setting an Alert State
• To mark an alert as new, fixed, or acknowledged, issue the setalert new|fixed|ack
<alert_ID> command, where <alert_ID> is the alert whose status you wish to
acknowledge.
Removing an Alert
• To remove an alert, issue the removealert <alert_ID> command, where <alert_ID>
is the alert you wish to remove.
Setting System Alerts
While most system alerts are generated automatically without any need for user configuration,
there are several types of alerts that you can specifically configure.
• Limits relating to Common Provisioning Groups (CPG) can be set by the user when creating
a CPG and can later trigger alerts. For information on setting the growth increment limits, see
