<h1 class="topictitle1">Auxiliary storage activity and save-while-active</h1>
<div><p>When choosing the time period for a save-while-active operation, evaluate
the activity in auxiliary storage without save-while-active processing. Ideally,
disks should be less than 30 percent busy before adding the activity for the
save operation. This is due to the heavy auxiliary storage activity that is
added with the save-while-active operation.</p>
