Abstract

LIC IASP VARY OFF.

Error Description

When IASPs are varied off the pages in memory are written in a  
specific sequence.  Specifically we write all the IASP pages    
that are not pinned with the write at shutdown attribute first,
then we write all pages that are pinned with the write at      
shutdown attribute.  It was discovered that we are not waiting  
for all of the outstanding aync writes to complete before we    
begin writing the pages pinned with the write at shutdown      
attribute.                                                      

Problem Summary

When IASPs are varied off the pages in memory are written in a  
specific sequence.  Specifically we write all the IASP pages    
that are not pinned with the write at shutdown attribute first,
then we write all pages that are pinned with the write at      
shutdown attribute.  It was discovered that we are not waiting  
for all of the outstanding aync writes to complete before we    
begin writing the pages pinned with the write at shutdown      
attribute.                                                      

Problem Conclusion

The code is changed to wait until all outstanding async writes  
of pages not pinned with the write at shutdown attribute        
complete before writing the pages pinned with the write at      
shutdown attribute.
