Re: One Extremely Busy Disk - Resolved

[prumschlag@xxxxxxxxxx]

Thanks to all who responded.  Lots of good ideas.

For those of you who care...........

I called IBM hardware support.  They verified that there was no indication in
the error logs of an impending disk problem.

After sorting through the system log for a while, I found a COBOL program that
seemed to be active about the time we were having the problem.  It turned out to
be the result of a poor coding technique.  I am no COBOL programmer, so I cannot
explain the significance of this, but the offending program was issuing an
INITIALIZE command before every READ file command.  After removal, everything
fell back into reasonable limits.

Thanks again.
Phil
