Sysplex_DASD_Dev_ContIndx_Warn

Sysplex_ DASD_ Dev_ ContIndx_ Warn monitors contention for a DASD device and issues a Warning alert when the index is greater than the specified threshold (.5 by default).

The formula is:

VALUE Sysplex_DASD.Average_Device_Contention_Index GT .500

If this situation is raised, notify a system programmer or DASD specialist. If the device is on a cached storage subsystem with RAID, this may not be much of a problem. If that is the case, the threshold should be adjusted to an appropriate value for the subsystem.
