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
