A single Hardware Management Console (HMC) must be selected as
the master HMC for
a Power® Enterprise Pool.
The HMC that is
used to create a Power Enterprise Pool is
initially set as the master HMC of
that pool. A redundant HMC can
be configured as a backup. You can set a new master HMC for a pool at any time.
All Power Enterprise Pool change
operations can be performed only by the master HMC for the pool.
When you power on or restart a server, ensure that the server is
connected to the master HMC.
This action ensures that the required Mobile CoD resources are assigned
to the server. When both the server and the master HMC are powered off, restart
the master HMC first,
then restart the server. This ensures that the server can connect
to the HMC to
obtain its Mobile CoD resource assignments.
Note: If a restarted server
is not able to contact the master HMC, it restarts with no
Mobile CoD resources. However, when the master HMC connects to the server
the Mobile CoD resources are automatically assigned to the server.
Upgrading the master HMC
You cannot perform any Power Enterprise Pool change operations
when you are upgrading the master HMC. After the upgrade
is complete, you can resume performing pool change operations on the HMC. If you plan to perform
any pool change operations when you are upgrading the master HMC, you must set a new
master HMC before
you start the upgrade.
Installing the master HMC
Performing a clean installation of the master HMC deletes all Power Enterprise Pool data from the HMC. After installation,
the HMC cannot
resume master HMC functions
for the pool until you perform a recovery operation. To avoid this
situation, you can set a new master HMC for the pool before
you start the clean installation of the current master HMC.
To perform a recovery operation after a clean installation of the HMC, run the following HMC command in a restricted
or removing a system from an established Power Enterprise Pool requires notification
An updated addendum
must be submitted to the Power Systems™ CoD project office (firstname.lastname@example.org) to add or remove
systems from Power Enterprise Pool.
When the update is processed, a new pool configuration file is posted
on the CoD website.
Before you remove the systems from a pool,
all assets (including Mobile CoD resources) that were originally purchased
with the system must be returned to that same system serial number. Mobile
assets that belong to a system might qualify for transfer to another
system serial number depending on normal qualifying guidelines and,
if possible, require more administrative action.
are removed from a pool can join another pool and contribute Mobile
CoD resources to the new pool and use Mobile CoD resources of other systems.
Mobile CoD resources require a pool ID to be recognized.
Eligible program authorizations
As a result
of authorized participation in a Power Enterprise Pools offering, you
are authorized to temporarily transfer entitlements for authorized
use of each Eligible Program from a Power Systems server that is participating
in the pool to another Power
Systems server that is also participating in the pool. You must
not exceed the maximum number of software licenses within the pool
for any specific software agreement.
Required maintenance service and support
each Power Enterprise Pool,
all participating systems must either be serviced by IBM under warranty or an IBM maintenance service agreement, or not be
serviced by IBM. In addition,
each eligible program that is entitled for IBM software maintenance (SWMA) on one or more
systems that are participating in the pool must also have a valid
SWMA agreement on every participating system in the pool that eligible
program will execute on.
Additional Power Enterprise Pool requirements
following are the additional Power Enterprise Pool requirements:
Any licenses for Power software
like AIX®, IBM i, and other Power software, that exist on
any system in a pool must also be licensed for at least one core on
each of the additional systems in the pool.
All systems in a pool must be owned by the same customer enterprise
Activations cannot be transferred, moved, or otherwise reassigned
across country boundaries.
Integrated Facility for Linux activations are
not supported as mobile activations within Power Enterprise Pools but can reside
separately on systems within a pool. AIX, IBM i, and Linux operating systems
and their workloads are all supported by Power Enterprise Pools.
