You can dynamically remove processor resources from a running
logical partition using the Hardware Management Console (HMC). This allows you to
reassign the processor resources to other logical partitions.
A
Linux® logical
partition supports the dynamic removal of processor resources only
if the following conditions are met:
- A Linux distribution
that supports dynamic logical partitioning is installed on the Linux logical partition.
Distributions that support dynamic logical partitioning include SUSE Linux Enterprise Server 9 and later versions.
- The DynamicRM tool package is installed on the Linux logical partition.
To download the DynamicRM tool package, see the Service and productivity tools for Linux on POWER® systems Web
site.
To dynamically remove processor resources from a running
logical partition using the HMC,
follow these steps:
- In the navigation pane, open ,
and click the managed system on which the logical partition is located.
- In the work pane, select the logical partition, click the Tasks button,
and click .
- Enter the amounts of processor resources that you want
to the logical partition to have into the fields in the Current column. If the logical partition uses shared processors, you might need
to adjust the number of virtual processors so that it is greater than
the number of processing units.
- Adjust the settings in the Options area
if necessary. You might need to increase the value in
the Timeout (minutes) field to allow enough
time for the HMC to
complete the operation. (These settings relate to how the managed
system removes processor resources dynamically. These settings are
not retained after the removal is completed.)
- Click OK.
