|
<div><p>In order to run Linux on certain iSeries™ servers, processor multitasking
|
||
|
|
must be disabled in i5/OS<sup>®</sup>.</p>
|
||
|
|
<p>Processor multitasking causes the iSeries processor to cache information
|
||
|
|
when switching between tasks. This function is not supported by Linux in certain iSeries servers.
|
||
|
|
An IPL of the server is required to activate the change. To disable processor
|
||
|
|
multitasking from an i5/OS command line, change the QPRCMLTTSK
|
||
|
|
server value to 0 (CHGSYSVAL QPRCMLTTSK '0') in the primary partition. If
|
||
|
|
a logical partition is started without disabling the multitasking function,
|
||
|
|
the IPL of the logical partition will fail with server reference code (SRC)
|
||
|
|
B2pp 8105 000010AE. </p>
|
||
|
|
<p>Before creating a logical partition, disable processor multitasking on
|
||
|
|
servers with the following feature codes:</p>
