<h1 class="topictitle1">Checklist 1: Configure disks on a new system</h1>
<div><div class="p">This checklist shows the sequence of tasks that you use to configure disks
on a new iSeries™ server.
Whether you need to perform all the tasks depends on the disk protection that
you want on your system. <a href="rzalydpconcepts.htm">Disk protection</a> provides
more information about the disk protection that is available. <div class="attention"><span class="attentiontitle">Attention:</span> When
you perform the tasks in this checklist, the system moves large amounts of
data. Make sure that you have completely <a href="../rzaiu/rzaiuintro.htm">saved your system</a> in the
event that you need to recover from an error situation.</div>
</div>
<div class="section"><h4 class="sectiontitle">Before you begin</h4><p>Print a copy of this checklist.
Check off the configuration tasks as you perform them. This checklist provides
an important record of your actions. It might help you diagnose any problems
that occur.</p>
<p>Most tasks in the checklist include references to other
topics. Refer to these topics if you need more information about how to perform
a particular task.</p>
