Monitor Description
The Fast/Wide SCSI Disk Array monitor is designed to monitor the operation of all supported Fast/Wide SCSI Disk Arrays on your system. If a problem is detected with a disk array, 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 Fast/Wide SCSI Disk Array monitor employs polling event detection. At regular intervals, the monitor requests status information from each disk array. 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 Fast/Wide SCSI Disk Arrays are protected from undetected hardware failure.

PSM State Control
The set_fixed utility must be used to return a hardware resource to the UP state following a failure. The monitor does not support automatic state control. (See "Using the set_fixed Utility to Restore Hardware UP State" in the EMS Hardware User's Guide.)
