At next RTOFS upgrade, please improve the scripts/exrtofs_glo_incup.sh script for restart file checking with the followings -

• When checking restart.a, restart.b and restart_cice, should be “||” not “&&” in the if block, as below -
  ....
  if [[ ! -e $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart.a ]] || \
  [[ ! -e $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart.b ]] || \
  [[ ! -e $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart_cice ]]; then
  ...

• if either one of rtofs_glo.t00z.n-${inc_hours}.restart.a ]] or $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart.b or $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart_cice not existed, the rtofs_glo_incup will fail at exec/rtofs_hycom when using these restart input data. When either one of needed resatrt file is not existed, should fail the job with error message as below example -
  “FATAL ERROR: $COMINm1/rtofs_glo.t00z.n-${inc_hours}.restart.a … rtofs_glo.t00z.n-${inc_hours}.restart_cice missing, exiting now."
