Monitor Description

The SCSI Enclosure Services monitor is designed to monitor the operation of all supported SES Enclosure monitor on your system. If a problem is detected with a storage system, the monitor immediately sends an event to Event Monitoring Service, which alerts you using the notification methods defined for the monitor. Clear, concise error messages identify the problem, what caused it, and what must be done to correct it.

The SES Enclosure monitor employs polling event detection. At regular intervals, the monitor requests status information from each storage system. The monitor then analyzes the data returned to determine if a hardware problem has occurred. If an error has occurred that warrants notification, an event is generated immediately.

The monitor is launched automatically when the system is started, ensuring that all supported SCSI Storage Systems are protected from undetected hardware failure.
