Aix Preferred Practices That Are Applicable To Power7; Power7 Mid-Range And High-End High Impact Or Pervasive Advisory - IBM Power7 Optimization And Tuning Manual

For virtualized environments, you can also use the IBM PowerVM Virtualization
Performance Advisor. Instructions for the IBM PowerVM Virtualization Performance
Advisor are available at:

For more information, see "Virtualization Performance Advisor" on page 158.
The number of online virtual CPUs of a single LPAR cannot exceed the number of active
CPUs in a pool. See the output of lparstat –i from the LPAR to see the values for online
virtual CPUs and active CPUs in pool.

4.3.2 AIX preferred practices that are applicable to POWER7

Here are the AIX preferred practices that are applicable to POWER7.
Preferred practices for installation and configuration
Preferred practices for installation and configuration are:
To ensure that your system conforms to the minimum requirements, see Chapter 3, "The
POWER Hypervisor" on page 55 and the references that are provided for that chapter
(see 4.4, "Related publications" on page 94).

4.3.3 POWER7 mid-range and high-end High Impact or Pervasive advisory

IBM maintains a strong focus on the quality and reliability of Power System servers. To
maintain that reliability, the currency of microcode levels on your systems is critical. Therefore,
apply the latest POWER7 system firmware and management console levels for your systems
as soon as possible. These service pack updates contain a collective number of High Impact
or PERvasive (HIPER) fixes that continue to provide you with the system availability you
expect from IBM Power Systems.
Before you migrate to POWER7, you see more benefits if your AIX level contains the
performance bundle set of APARS. Visit IBM Fix Central
(http://www.ibm.com/support/fixcentral/) to download the latest service pack (SP) for
your POWER7 Systems.
Furthermore, you should:
Define an upgrade or update plan to bring your servers to the latest fix levels.
Concurrently update servers that are running older firmware levels to the latest level.
See the associated SP readme files for information about the specific fixes included in
each service pack. Sections of readme files that describe more tips and considerations
are a helpful resource as well.
When you install firmware from the HMC, avoid the do not auto accept option. Selecting
this advanced option can cause firmware installation problems.
