This is a report on the processing of DD153

From: AXPGS3::MACROUSA "LNGS US MACRO group" 27-MAR-2000 09:02:23.07
Subj: Start COPY of FIRST (#1) file of DD153 (RUN015186) Selected CPU:3/DISK:9

During the download from tape to disk we found this problems

        WARNING-- In DD153 RUN015205.ZEB expecting 765197 vs 757941
        WARNING-- In DD153 RUN015206.ZEB expecting 763341 vs 0

that Yiannis fixed:

        DD153 G.S. copy broken - repaired today

     While reprocessing MACRO data, we found out that DD153 (G.S. copy)
  was corrupted; only the first 25 files were OK (up until RUN015204.ZEB).
  The rest 14 (RUN015205-RUN015219) produced read parity error.
     I got the BACKUP tape and restored its contents on disk (succesfully)
  and then produced a new version of DD153 (succesfully) that will take
  the place of the original one, once that tape is out of the ROBOT.
     I don't know if the other 4 copies (BO/FR/NA/PI) have had problems
  or not; in fact, the file DD153.LOG and DD153.LBK have clear signs
  of some abnormal conditions when these tapes were produced.

The files copy from BACKUP tape to disk lasted ~ 9hrs.

So I launched the ZEB2RAW for this DD

From: AXPGS3::MACROUSA "LNGS US MACRO group" 27-MAR-2000 18:03:15.69
Subj: Submitted FIRST (#1) ZEB2RAW job of DD153 (RUN015186) Selected CPU:3/DISK:9
From: AXPGS3::MACROUSA "LNGS US MACRO group" 27-MAR-2000 20:43:45.87
Subj: Submitted LAST (#39) ZEB2RAW job of DD153 (RUN015219) Selected CPU:3/DISK:9

Conversion of ZEBRA to RAW lasted ~ 2.7 hrs.

Then the processing of the RAW RUN files started. It lasted ~ 8.5 hrs

DD153 is now completed. It took 9+2.7+8.5= ~20.2 hrs.
