<h1 class="topictitle1">Checklist 9: Remove disk units that have device parity protection from
|
||
a disk pool without mirrored protection</h1>
|
||
<div><p>This checklist shows the sequence of tasks that you use to remove one or
|
||
more disk units from an input/output adapter with built-in device parity protection.
|
||
These tasks apply when the disk pools containing the disk units do not have
|
||
mirrored protection and when device parity protection is started for the IOA.
|
||
Use these tasks when you are permanently removing disk units from your system.
|
||
Do not use these tasks when your are repairing or replacing a failed hard
|
||
disk. You must restart your server to dedicated service tools (DST) mode to
|
||
perform the tasks in this checklist.</p>
|
||
<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 class="section"><h4 class="sectiontitle">Before you begin</h4><p>Print a copy of this checklist.
|
||
Check off the configuration tasks as you or the service representative perform
|
||
them. This checklist provides an important record of your actions. It may
|
||
help you diagnose any problems that occur.</p>
|
||
</div>
|
||
<div class="p">Most tasks in the checklist include links to other topics. Refer to these
|
||
topics if you need more information about how to perform a particular task.
