<div><p>Learn how to assign your I/O adapters to logical partitions.</p>
|
||
|
|
<div class="p">Before changing your hardware configuration, use the LPAR Validation
|
||
|
|
Tool (LVT). This tool allows you to test the placement of i5/OS<sup>®</sup> and logical
|
||
|
|
partition hardware within the server to ensure that the placement is valid.
|
||
|
|
The output generated from the LVT will validate the placement of hardware
|
||
|
|
and ensure that your logical partition is configured properly. Refer to <a href="http://www.ibm.com/eserver/iseries/lpar/sysdesign.htm" target="_blank">Logical Partition</a> <img src="www.gif" alt="Link outside Information Center" /> for information on the LPAR Validation Tool (LVT).<div class="note"><span class="notetitle">Note:</span> Incorrect
|
||
|
|
placement of adapters for logical partitions could result in unpredictable
|
||
|
|
behavior in the logical partition.</div>
|
||
|
|
<p>If you want to use real hardware
|
||
|
|
devices like communication lines, disk units, internal tape and CD devices
|
||
|
|
in a logical partition, you must assign the controlling IOAs explicitly to
|
||
|
|
the logical partition. These instructions do not apply to virtual devices
|
||
|
|
like virtual Ethernet, virtual disk, virtual CD, or virtual tape provided
|
||
|
|
by a hosting i5/OS partition.</p>
|
||
|
|
<p>The
|
||
|
|
logic to identifying IOAs is contained in the IOPs to which they are attached.
|
||
|
|
For logical partitions, IOAs are not connected to IOPs so their identity may
|
||
|
|
not be determined. In fact, card positions used by logical partitions will
|
||
|
|
have one of these descriptions:</p>
|
||
|
|
<ul class="simple"><li><strong>Empty position</strong>: IOA not yet installed.</li>
|
||
|
|
<li><strong>Occupied position</strong>: IOA installed, but not yet assigned to a logical
|
||
|
|
partition or not supported by the logical partition to which it is assigned.</li>
|
||
|
|
<li><strong>Communication IOA</strong>: resource is a communication adapter and supported
|
||
|
|
by the logical partition to which it is assigned.</li>
|
||
|
|
<li><strong>Multiple Function IOA</strong>: resource is a multiple function adapter
|
||
|
|
and supported by the logical partition to which it is assigned.</li>
|
||
|
|
<li><strong>Disk Controller</strong>: resource is a disk controller and supported by
|
||
|
|
the logical partition to which it is assigned.</li>
|
||
|
|
<li><strong>Generic adapter</strong>: IOA installed and may be supported by the logical
|
||
|
|
partition to which it is assigned.</li>
|
||
|
|
<li><strong>Storage IOA</strong>: resource is a storage adapter and supported by the
|
||
|
|
logical partition to which it is assigned.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Due to this non-specific identification, it is very important to note
|
||
|
|
the logical and physical address of the card positions to be used by a logical
|
||
|
|
partition.A logical partition must have access to the bus on which its IOAs
|
||
|
|
reside. The only restriction is that if the bus is shared with an i5/OS partition,
|
||
|
|
the i5/OS partition
|
||
|
|
must own it, shared (own shared) and the logical partition must use it shared
|

(use shared).</p>
