Browse Source 
If a suspended z/VM guest has been logged off before the resume the
'SET SMSG IUCV' CP command need to be repeated to reenable sending
message via SMSG. This fixes the following error:

HCPMFS057I H4214002 not receiving; SMSG off
Error: non-zero CP response for command 'SMSG H4214002 CMM SHRINK 5010': #57
