Problem summary

  • APAR NUMBER:  PJ40772
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  TAPE I/O AND ERROR RECOVERY
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    When there is a timeout on a write operation issued to the dump
    tape then the dump is aborted and no tape switch occurs.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/cp/cedt.cpy
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    None.
    
    Support Files:
    None.
    
    OTHER BINARIES TO BUILD: YES
    (C) <sys>/obj/cccpse.o
    (C) <sys>/load/CPS0.so
    
    COMMENTS:
    If a system error occurs that requires writing more data than
    will fit into the Dump Buffer Area then CCCPSE must write some
    of that data directly to the tape instead of letting it remain
    in the DBA. If one of these writes fails because the write
    command does not complete in the allocated amount of time then
    the dump is aborted and no tape switch occurs. This leaves a
    potentially unusable device as the active dump tape and
    subsequent attempts to use the drive can result in the same
    failure.
