<h1 class="topictitle1">Checklist 2: Add disk units without device parity protection</h1>
|
||
<div><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. </p>
|
||
<div class="section"><h4 class="sectiontitle">Disk pools with mirrored protection</h4><p>You can add
|
||
disk units to a disk pool that has mirrored protection without stopping and
|
||
starting mirrored protection. You must add disk units in pairs with equal
|
||
capacities. The added units will always be paired with each other. You might
|
||
want to choose a later time, when your system can be unavailable for several
|
||
hours, to stop and start mirrored protection. When you start mirrored protection
|
||
again, the system evaluates the pairing for all disk units on your system.
|
||
This might provide a higher level of availability for failures that affect
|
||
an input/output adapter (IOA), an input/output processor (IOP), or a bus.</p>
|
||
</div>
|
||
<div class="section"><h4 class="sectiontitle">Attention</h4>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 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>
