Abstract

LIC MSD IPL NOT SHUTTING DOWN COMPLETELY.

Error Description

If a system crashes when there is pending link loader work the  
following IPL will be a MSD IPL.  When this MSD IPL ends, the  
code that writes changed pages to dasd will fail, causing the  
next IPL to do additional processing during the SM recovery    
step.                                                          

Problem Summary

If a system crashes when there is pending link loader work the  
following IPL will be a MSD IPL.  When this MSD IPL ends, the  
code that writes changed pages to dasd will fail, causing the  
next IPL to do additional processing during the SM recovery    
step.                                                          

Problem Conclusion

The MSD IPL shutdown code is taking an exception and failing    
when it touches memory that has not been initialized since we  
performed a MSD IPL.  The code is changed to recognize the IPL  
type, and if it is a MSD IPL, limit the amount of memory it    
processes to only the memory that was initialized.
