Abstract

LIC-OTHER-SRCB6005121-INCORROUT WHILE REMOVING UNIT FROM IASP.

Error Description

During a DB extent move operation, the extent is moved, but the
old extent can be deleted before other code expects it, leading
to a exception that is not handled properly.                    
                                                               
This exposure is in the code handling the move of extents      
from one unit to another.  This code is involved in disk        
removal, but also in disk balancing code.  Balancing can        
occur at disk add time (Add & Balance), or by using            
STRASPBAL to balance capacity or drain a disk unit.
