Problem summary

• APAR NUMBER:  PJ40698
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  IPL
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  Catastrophic CTL-1 possible when ipling with an unmounted copy
  module
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/ol/ib06.cpy
  (C) base/ol/ib03.cpy
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  None.
  
  Support Files:
  None.
  
  OTHER BINARIES TO BUILD: YES
  (C) <sys>/obj/iplb.o
  (C) <sys>/load/IPLB.so
  
  COMMENTS:
  A copy module mount status is not checked until much later in
  restart. This is problematic since it is a bit late to properly
  abort a copy or prevent the processor from joining the complex
  with an unmounted module. In the event that copy reaches end of
  job during this time and a module swap is performed, the
  processor with an unmounted copy module will take a
  catastrophic error.
  

Problem conclusion

• SOLUTION:
  Copy modules (target modules of ZMCPY ALL operations) will be
  checked for mount status like real-time modules during roll
  call in IPLB. A new warning message of IPLB0125W will be issued
  if a copy module is found to not be mounted and a subsequent
  message of IPLB0022A will prompt for whether IPL is to continue
  as is done for message IPLB0121W.
  
  COREQS: NO
  None.
  
  MIGRATION CONSIDERATIONS: YES
  Functional, automation, and operation changes:
  New message:
  IPLB0125W
  
  
  
  BUILD COMMANDS AND INSTRUCTIONS: YES
