  V XCF,sysname,OFF,DUMP,REIPL        will generate a 
wait state while will drive AutoIPL processing.

 Unfortunately, the architected interface to the machine (LPAR) 
which z/OS AutoIPL uses to IPL standalone dump or re-IPL z/OS 
does not provide a way for z/OS to supply a wait state code. 
So there can be no logging of the wait state to the HMC.  The
only way to determine the wait state code is a standalone dump.
When AutoIPL re-IPLs z/OS directly without a standalone dump,
there is no way to determine what the wait state code was.

  Whenever a requirement come in to z/OS about this lack
of logging, I respond that this is a requirement for the machine (LPAR),
not z/OS.  When/if LPAR chooses to enhance the interface to allow
z/OS to provide a wait state code, z/OS will be happy to make
use of it.
