Error description

  • Error ANR1330E & ANR1331E reported during backup stgpool process
    with Invalid Frame detected message. This is seen because we are
    running ?backup stgpool? and ?migration? at the same time, and
    TSM?s Admin reference says ?If migration for a storage pool
    starts during a storage pool backup, some files may be migrated
    before they are backed up.".
    
    The trace run for the Backup Stgpool would show the following
    information:

Local fix

  • Avoid running 'backup stgpool' & 'migration' process
    simultaneously.
