<h1 class="topictitle1">Include disk units in a parity set</h1>
|
||
|
|
<div><p>You can select which disk units you want to include in a parity set. When
|
||
|
|
you attach a new disk unit to an existing I/O processor that has device parity
|
||
|
|
protection, you can include the disk unit in a device parity set with other
|
||
|
|
disk units of similar capacity.</p>
|
||
|
|
<p>If you want to include a disk unit in an independent disk pool that is
|
||
|
|
unavailable, you must first IPL your system. For all other disk
|
||
|
|
pools, you need to restart your system to dedicated service tools (DST) mode
|
||
|
|
before including them in a parity set.</p>
|
||
|
|
<p>To include a disk unit in a parity set, follow these steps:</p>
|
||
|
|
<ol><li>Expand <span class="uicontrol">Disk Units</span>.</li>
|
||
|
|
<li>Select the disk units that you want to include.</li>
|
||
|
|
<li>Right-click a selected disk unit and select <span class="uicontrol">Include in Parity
|
||
|
|
Set</span>.</li>
|
||
|
|
<li>From the resulting dialog box, click <span class="uicontrol">Include</span> to
|
||
|
|
include the selected disk units in a parity set.</li>
|
||
|
|
</ol>
|
||
|
|
<p>Adding three or more disk units requires you to create a new parity set.
|
||
|
|
The include function does not work when creating a parity set. To create
|
||
|
|
a parity set, go to <a href="rzalystartdpy.htm">Start device parity protection</a>.</p>
