Abstract

LIC-DISK-OTHER-UNPRED HYPERSWAP SECONDARY MIGRATION FAILURE FOR
CERTAIN MIGRATION SEQUENCES

Error Description

When migrating from one Hyperswap Secondary to another without  
an IPL, there is a recommended sequence to follow.  Several    
issues were found while testing other possible sequences and by
fixing these, we can improve the robustness of the design and  
avoid inadvertent problems customers might hit if they don't    
follow the recommendation.  For the most part, the problems    
encountered put the hyperswap manager in a invalid state that  
required an IPL for recovery.                                  

Problem Summary

When migrating from one Hyperswap Secondary to another without  
an IPL, there is a recommended sequence to follow.  Several    
issues were found while testing other possible sequences and by
fixing these, we can improve the robustness of the design and  
avoid inadvertent problems customers might hit if they don't    
follow the recommendation.  For the most part, the problems    
encountered put the hyperswap manager in a invalid state that  
required an IPL for recovery.                                  

Problem Conclusion

Fixes now allow migration from one Hyperswap Secondary to      
another without an IPL even when the recommended reconfiguration
sequence is not strictly followed.
