Hello,
I want to remind people on shift that they are expected to
periodically load a new tape in order to back up spud data, as
required by the data archiving script.
_ This script is running on a terminal window on dblast09
_ you should periodically check if a tape is done. A large white
window will pop up
_ Go to spud6 (the spud with a white tape drive on top) and put
in a new tape
_ press return on the terminal window. See also below for more info
A new tape is needed approx every 2.5 hours and about 12 tapes are needed
per full spud disk. It would be nice if you write on the tape cover "tape
2", "tape 3" .. and the machine name (in this case, spud6)
There is some urgency to move the tape drive by wendsday so please keep it
up.

Subject: Procedure to archive Spud data to tape
Hi all.
Here are some instructions for archiving data on the Spuds to tape,
cd /data/Daq/ArchiveToTape
./ArchiveData
Each data directory (/data/Daq/commis and /data/Daq/data) will be written to
a new set of tapes. For each set of tapes, the procedure first divides all the
data files into 1 or more tape lists, each totalling up to 150 Gigabytes of
data. At the same time, it sorts the files by Run #, so they are written to
tape in increasing order. This may take 2-3 minutes.
A window will pop-up to alert you when a tape needs to be loaded. The window
can just be closed. However, closing the window does not cause the archiving
procedure to continue (it's just an alert). You must go to the window you
are running the procedure from and hit RETURN at the prompt.
A few notes,
Each tape is a a separate TAR archive.
A log file is created in /data/Daq/ArchiveToTape for each tape set.
The tape drive must be on the Spud being archived.
