DB2 FOR LUW / DB2FORLUW / 980 - DB2

HADR standby can shut down reporting "Invalid format in Extent 
header" when the following conditions are met: 
  * The primary and standby share an archive log path 
  * The standby is using a mirror log path 
  * The standby is going through local or remote catchup 
 
Our issue is that the active log path receives updates from the 
archive log path and the HADR primary.  The mirror log path only 
receives updates from the HADR primary.  This can cause 
information in the log headers to diverge during local/remote 
catchup.  This causes log header inconsistencies which results 
in the HADR standby being shutdown.
