|

|
<div><p>Learn what release levels are supported and how you can partition
|
||
|
|
your system to support new functions.</p>
|
||
|
|
<p>Only Version 4 Release 4 (V4R4) and later releases of the i5/OS™ (R) operating
|
||
|
|
system support logical partitions. (All releases of the i5/OS(TM) operating
|
||
|
|
system support logical partitions.) V4R4 is the earliest release that is supported
|
||
|
|
in any logical partition.</p>
|
||
|
|
<p>You can install up to four different releases on a single server. The releases
|
||
|
|
that you can install on a particular server depend upon which releases are
|
||
|
|
supported on the server model and upon which release you choose to install
|
||
|
|
on the primary partition.</p>
|
||
|
|
<div class="p">If the primary partition is running V4R5 or earlier, you can install and
|
||
|
|
run the following releases on the secondary partitions, provided that each
|
||
|
|
release is supported by the server model: <ul><li>The release before the release on the primary partition</li>
|
||
|
|
<li>The release on the primary partition</li>
|
||
|
|
<li>The release after the release on the primary partition</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The only exception to this rule is when the primary partition of 6xx, 7xx,
|
||
|
|
or Sx0 servers runs V4R4. In this case, you can install V5R1 on a secondary
|
||
|
|
partition of those servers.</p>
|
||
|
|
<div class="p">If the primary partition is running V5R1 or later, you can install and
|
||
|
|
run the following releases on the secondary partitions, provided that each
|
||
|
|
release is supported by the server model: <ul><li>The release before the release on the primary partition</li>
|
||
|
|
<li>The release on the primary partition</li>
|
||
|
|
<li>The release after the release on the primary partition</li>
|
||
|
|
<li>The second release after the release on the primary partition</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The 6xx and Sx0 servers support all releases from V4R4 through V5R2. The
|
||
|
|
7xx servers support all releases from V4R4 through V5R3. The 6xx, 7xx, and
|
||
|
|
Sx0 servers do not support the shared processor pool. Because of this, you
|
||
|
|
can partition these models only if the server has 2 or more processors.</p>
|
||
|
|
<p>The 820, 830, 840, and 270 servers with a single processor support V5R1
|
||
|
|
and later releases on all logical partitions. The 820, 830, and 840 servers
|
||
|
|
with 2 or more processors support V4R5 and later releases on all logical partitions.
|
||
|
|
The 270 servers with 2 processors support V5R1 and later releases on the primary
|
||
|
|
partition and V4R5 and later releases on secondary partitions.</p>
|
||
|
|
<p>The 810, 825, 870, and 890 servers only support V5R2 or later releases
|
||
|
|
in the primary and secondary partitions.</p>
