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

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

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.
