<h1 class="topictitle1">Checklist 6: Move disk units between mirrored disk pools</h1>
|
||
|
|
<div><p>This checklist shows the sequence of tasks that you use to move one or
|
||
|
|
more disk units from one basic disk pool to another basic disk pool. Use these
|
||
|
|
tasks when one or more of the disk pools has mirrored protection. You cannot
|
||
|
|
move disk units when mirrored protection is active. Instead, you remove mirrored
|
||
|
|
pairs from the source disk pool and add them to the destination disk pool.
|
||
|
|
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 perform them. This checklist provides
|
||
|
|
an important record of your actions. It may help you diagnose any problems
|
||
|
|
that occur.</p>
