<h1 class="topictitle1">Forcing a main storage dump on servers with logical partitions</h1>
|
||
|
|
<div><p>When the server has a failure, it may create a main storage dump.
|
||
|
|
A main storage dump copies the contents of the server's main storage to disk.
|
||
|
|
It can be an important tool for problem analysis. When your server performs
|
||
|
|
a main storage dump, <span class="uicontrol">contact your customer support representative.</span></p>
|
||
|
|
<p>On a server with logical partitions, there are two kinds
|
||
|
|
of main storage dumps you can perform:</p>
|
||
|
|
<ul><li>A main storage dump of the <a href="#rzaitforcemsd__server">server</a>.</li>
|
||
|
|
<li>A main storage dump of a <a href="#rzaitforcemsd__partition">secondary
|
||
|
|
partition</a>.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Failures in the primary partition caused by server processing hardware
|
||
|
|
or main storage hardware will cause the entire server to fail. Software failures
|
||
|
|
in a secondary partition will cause only that logical partition to fail.</p>
|
||
|
|
<p>A server failure may cause a server main storage dump. A secondary partition
|
||
|
|
failure may cause a main storage dump only on that logical partition.</p>
|
||
|
|
<p>When you are directed to by customer support or your service representative,
|
||
|
|
you can force a main storage dump on a server with logical partitions.</p>
|
||
|
|
<div class="section" id="rzaitforcemsd__server"><a name="rzaitforcemsd__server"><!-- --></a><h4 class="sectiontitle">Main storage dump of the server</h4><p>You
|
||
|
|
should only perform a server main storage dump when directed by a service
|
||
|
|
representative.</p>
|
||
|
|
<div class="attention"><span class="attentiontitle">Attention:</span> When you perform a server main storage
|
||
|
|
dump, every active secondary partition will also perform a main storage dump.
|
||
|
|
They will all then restart. This could take a long time.</div>
|
||
|
|
<p>A Work with Partition Status display will appear on the secondary partition's
|
||
|
|
console unless a main storage dump was already in progress. In that case,
|
||
|
|
a Main Storage Dump display will appear on the secondary partition console.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section" id="rzaitforcemsd__partition"><a name="rzaitforcemsd__partition"><!-- --></a><h4 class="sectiontitle">Main storage dump of a secondary partition</h4><p>You
|
||
|
|
should only perform a secondary partition main storage dump under the direction
|
||
|
|
of a service representative. To preform a main storage dump on a secondary
|
||
|
|
partition, you should be working with the remote control panel. <span class="uicontrol">Function
|
||
|
|
22</span> forces a main storage dump on the remote control panel.</p>
|
||
|
|
<p>In the event you cannot perform function 22 (Force main storage dump) on
|
||
|
|
a secondary partition, perform a system main storage dump under the direction
|
||
|
|
of your service representative. When the Main Storage Dump Occurred display
|
||
|
|
appears on the primary partition's console, press Enter, and select option
|
||
|
|
6 (Dump all partitions). A main storage dump is initiated for each active
|
||
|
|
partition and needs to be copied to disk for each partition.</p>
