IT08572: DYNAMICALLY MODIFYING AUTO_TUNE AFFECTS THE SETTINGS OF OTHER AUTO_* CONFIG PARAMS, EVEN IF THEY WERE EXPLICITLY SET IN THE CONF

APAR status

• Closed as program error.

Error description

• If an AUTO_* config parameter such as AUTO_REPREPARE is not
  present in the config file--not explicitly set by the user, in
  other words--it is supposed to take the value of AUTO_TUNE, even
  if AUTO_TUNE is modified dynamically. However, if an AUTO_*
  parameter is explicitly set by the user in the config file, the
  value of AUTO_TUNE is not supposed to affect it, even if
  AUTO_TUNE is changed dynamically.
  
  Currently if you have the following in your config file:
  
  AUTO_TUNE 1
  AUTO_REPREPARE 1
  
  and the user runs this command:
  
  onmode -wm AUTO_TUNE=0
  
  the effective value of AUTO_REPREPARE is also set to 0. Because
  it was present in the config file, we should instead continue to
  honor the value set explicitly by the user.
