PSH provides problem diagnosis on the SP and the host. Regardless of where a fault occurs, you can view and manage the fault diagnosis from the SP or the host.
When possible, PSH initiates steps to take the component offline. PSH also logs the fault to the syslogd daemon and provides a fault notification with a message ID. You can use the message ID to get additional information about the problem from the knowledge article database.
A PSH console message provides this information about each detected fault:
Type
Severity
Description
Automated response
Impact
Suggested action for system administrator
If PSH detects a faulty component, use the fmadm faulty command to display information about the fault. See Check for Faults.
