RE: Occasional CPF6702 Media Errors on Magstar 3570 tapes

[Bryan Burns <burnsbm@xxxxxxxxxxxxxxxxxxxx>]

Thanks for the reply Dave, I will give it a try.  (We are running V4R4 on a 
620 and have the latest cume installed).

Thanks too for all your other contributions to this list and the MAPICS 
list.  You seem to always have clear answers to problems that I can 
identify with.

Bryan,

Try ordering and installing the Save/Restore group PTF for your release of
OS/400.  There's a BUNCH of LIC PTF's for the 3570 drives, and they haven't
stopped coming yet.

Our MAPICS back ups, which we perform five days a week, fail every two or
three months, due to CPF6702 media errors.

I have yet to see the cleaning indicator even be activated on this machine, 
but when the errors started occurring last fall, we started cleaning the
3570 every Monday.  We still get the errors.

We have one tape for each day of the week so I would not think it is an
overuse problem.

In the beginning of the year, an IBM CE came out and looked at the machine
and had us load a  PTF or two.  We still get the errors.

I do take the back up tapes home with me each night in a little padded
envelope.  Could  the tapes be picking up contaminants through the handling 
of them?  Also, some MIS personnel used to put stock labels over the
barcode labels. Some of the stock labels have since been removed, leaving a 
pretty clean bar code label but with some residue.  Could a dirty label
cause a media error?

After the most recent failure, I successfully initialized the tape in
question.  I was told that if it can be initialized, then it is actually a
good tape.  Is this true?

Is it normal to have this frequency of errors?  If not, does anyone in this 
great midrange-list community have a solution?
