<h1 class="topictitle1">Recover an independent disk pool</h1>
|
||
|
|
<div><p>If you are experiencing problems accessing an independent disk pool or
|
||
|
|
making it available, there may be a problem with the disk pool. Possible
|
||
|
|
problems include: </p>
|
||
|
|
<ul><li>The configuration source is corrupted. When corruption occurs, the independent
|
||
|
|
disk pool will appear to have no disk units in it. The disk pool may also
|
||
|
|
appear to have no disk units in it if it is switched to another node in a
|
||
|
|
clustered environment. Before you attempt a recovery, make sure that no other
|
||
|
|
system owns the disk pool. If you know the serial numbers of the disk units
|
||
|
|
in the independent disk pool that might need recovery, make sure you are on
|
||
|
|
the system that owns those disk units and that they show as nonconfigured.
|
||
|
|
<p>If the configuration source is corrupted, you can select to recover the
|
||
|
|
configuration information about the configuration source. Recovering the
|
||
|
|
configuration attempts to determine the original configuration and recover
|
||
|
|
it. During this process, the independent disk pool might need to be cleared,
|
||
|
|
destroying all data on the disk units in the pool. If the disk pool needs
|
||
|
|
to be cleared, a message is displayed telling you of this and allowing you
|
||
|
|
to cancel the recovery. </p>
|
||
|
|
</li>
|
||
|
|
<li>The mirrored disk unit of the configuration source is damaged. When this
|
||
|
|
happens, the mirrored configuration source becomes unknown. The disk pool
|
||
|
|
will be unavailable, and you must recover the configuration information of
|
||
|
|
an unknown configuration source before making it available. You should only
|
||
|
|
attempt to recover the state of the unknown configuration source when you
|
||
|
|
know its mirrored disk unit was active before the failures that caused the
|
||
|
|
state to become unknown. </li>
|
||
|
|
</ul>
|
||
|
|
<div class="p">To attempt to recover an independent disk pool, follow these steps: <ol><li>In iSeries™ Navigator,
|
||
|
|
expand <strong>My Connections</strong> (or your active environment).</li>
|
||
|
|
<li> Expand any iSeries server. </li>
|
||
|
|
<li>Expand <strong>Configuration and Service</strong>.</li>
|
||
|
|
<li> Expand <strong>Hardware</strong>. </li>
|
||
|
|
<li>Expand <strong>Disk Units</strong>. </li>
|
||
|
|
<li>If the Service Tools Signon dialog box displays, sign on to service tools.</li>
|
||
|
|
<li>Select <strong>Disk Pools</strong>. </li>
|
||
|
|
<li>Right-click the problematic disk pool. If iSeries Navigator detects one of the
|
||
|
|
problems listed above, then <strong>Recover Configuration</strong> or <strong>Recover Unknown
|
||
|
|
Configuration Source</strong> appears in the list. If you see either of these
|
||
|
|
options, select it to continue. </li>
|
||
|
|
<li>Follow the instructions on the dialog box displayed.</li>
|
||
