IJ51706: ENABLE AFMCHECKREFRESHDISABLE CONFIG AT THE FILESET LEVEL

APAR status

• Closed as program error.

Error description

• afmCheckRefreshDisable is a tunable at the cluster level today
  to avoid refresh from going to the Filesystem itself and return
  from the dcache. But it applies to all AFM filesets in the
  cluster, when tuned. Need a fileset level tunable to do the same
  so that it doesn't impact all other filesets in the cluster like
  it does today.
