<div><p>The ability to move processor power dynamically becomes important
|

|
|
when you need to adjust to changing workloads.</p>
|
||
|
|
<div class="section"><p>Processors have minimum and maximum values associated with them.
|
||
|
|
These values enable you to establish a range within which you can dynamically
|
||
|
|
move the resource without needing to restart the logical partition. Minimum
|
||
|
|
values dictate what is required to restart the partition. A minimum value
|
||
|
|
of zero is valid. A partition with zero processors or processing units is
|
||
|
|
not functional.</p>
|
||
|
|
<p>For both shared and dedicated processors you can specify
|
||
|
|
a minimum value equal to the minimum amount of processing power needed to
|
||
|
|
support the logical partition. The maximum value must be less than the amount
|
||
|
|
of processing power available on the system. If you change either the minimum
|
||
|
|
or maximum value, it will require you to restart the entire partition. If
|
||
|
|
the minimum value is not met for all logical partitions, only the primary
|
||
|
|
will restart.</p>
