Abstract

OSP-OTHER F/QYASPVARY T/QYASPACT MSGCPFB8E5 IASP VARY ON FAILS

Error Description

Due to a very small timing window, the vary on of an IASP could
fail with CPFB8E5. The timing window comes into play when      
internal processing checks a bit and expects a certain value to
allow vary on processing to continue. Some of the internal      
processing was being performed asynchronously and so the bit    
wasn't set to the correct value at the specific time.          
                                                               
Code will be enhanced to allow synchronous processing and      
should eliminate the window altogether.                        
                                                               
Possible Work Around: Vary the IASP off from the failed state  
then vary the IASP on again.                                    

Problem Summary

Please see see the Error Description section.                  

Problem Conclusion

Code was enhanced to allow synchronous processing which        
eliminates the timing window.
