Timing condition during add of multipath LUNs leads to blocking
mechanism being held while in an interrupt handler.            

Problem Conclusion

When adding LUNs to an ASP, there is a problem with getting all
paths updated and in sync following the add.  This fix will    
insure that all paths get updated correctly.                    

Temporary Fix

                       *********

                       *********                                

Comments

Circumvention


A work around would be to assign the LUNs to the IBM i partition

and add them to the ASP with only 1 path.  After the add to ASP
is complete, then assign the LUN to the other paths.
