Both the PCI bus utilization and processor utilization for the OSA adapter indicate a high percentage of use. Poor OSA adapter performance is likely because of high OSA adapter utilization rates. To determine this, the following metrics in the OSA-Express channels table are used:
This situation occurs when, for three consecutive intervals, the PCI utilization per minute is greater than 80% and the processor utilization per hour is greater than 95%. To resolve this problem, use the following procedures:
Formula: PCI Utilization Per Minute >= 80 AND Processor Utilization Per One Hour >= 95
