Difference Between Hardware Event Monitoring and Hardware Status Monitoring
The EMS Hardware Monitors detect errors, but they do not retain the details of events. However,
the error can persist until it is rectified. For example, a failed disk remains in the same state until
it is replaced.
Hardware status monitoring is an extension of event monitoring that converts an event to a change
in device status. This conversion, performed by the PSM, provides a mechanism for retaining the
event details by storing the resultant status in a log file. This ability provides compatibility with
applications such as HP Serviceguard, which require a change in device status to manage
high-availability packages.
