DASD device percent busy warning situation

 

Suggested Actions

The indicated DASD device utilization exceeds the current Warning threshold. This condition may represent a current or pending performance problem if any service class period is missing its goal because of I/O delay for this device. This threshold is 100% by default and should be set to a lower value only when pursuing a chronic DASD performance problem.
