Did you know you can have LPARS that own IVE/HEA ports participate in a Live Partition Mobility operation? Feature Overview
• Live Partition Mobility with Host Ethernet Adapter/Integrated Virtual Ethernet is new feature added to AIX in bos61J (AIX 6.1 TL5) release. • This feature allows users to perform Live Partition Mobility (LPM) from an AIX partition if certain requirements are met. • With this feature, users can perform LPM while IVE/ HEA are assigned to the migrating partition. • Feature uses HMC commands to perform the migration. • The actual migration is performed by the HMC. AIX simply executes commands on HMC to perform migration.
Feature Requirements
To perform Live Partition Migration from AIX, following requirements must be satisfied. – Partition Requirements • Source and Target partition must be capable for partition migration. • Source AIX partition must not have any physical resources as “Required” in its partition profile in HMC. • Source AIX partition must not have any other physical resources besides IVE/HEA. - Configuration Requirements • IVE/HEA must not have “Required” setting in HMC. However, it can have “Desired” setting. • In AIX partition, all IVE/HEA must be configured under EtherChannel as primary adapters. • All primary adapters in EtherChannel must be IVE/HEA • EtherChannel must have a backup adapter, and the backup adapter must be a virtual ethernet adapter. • Migrating AIX partition must have at least one EtherChannel configured with primary adapter as IVE/HEA and backup adapter as virtual ethernet adapter. • Maximum of four EtherChannel is supported in migrating partition. • EtherChannel failover must be functional. • If migration is between two HMC, you must setup SSH authentication between source and remote HMC. You must run mkauthkeys command on source HMC prior to starting migration.

Planning for IBM i Release Life Cycles and Support The support and life cycle strategies for IBM i reflect the fact that companies run their most critical business applications on the
platform. These strategies include the practice to support an IBM i release until the next two releases have been made available, plus
twenty four months – which translates to approximately six years support, given the delivery of a new release approximately every two
years. Automated operating system upgrades are available to easily move up to the next two releases providing for an ongoing supported
IBM i environment. For example, customers running IBM i 5.3 or 5.4 can easily upgrade to IBM i 6.1. IBM i 5.4 and 6.1 are currently
supported releases. With the introduction of the next release in 2010, support for i 5.4 is planned to extend until at least 2012.

POWER 750 Express
The new Power 750 Express Server was announced in February of this year and is now available for new server orders. General availability for
upgrades and MES orders is scheduled for June 2010.
The IBM Power 750 Express server packs a lot of punch in a 4u server. It is physically similar in structure and options to the Power 6 550 but
with much more capability in the same footprint. With up to 32 POWER7 processor cores and 512GB of memory, the Power 750 is an ideal
server for consolidating multiple applications or as a large database server. The new Active Memory Expansion feature introduced with
POWER7 further extends available memory to applications by using a compression/decompression technology. The Power 750 is an excellent
entry level, mid-range server for mission critical AIX, IBM i or Linux applications. For database workloads, the leading performance of the
POWER7 processors provides the compute power needed with fewer processors, lowering per core software licensing costs. The flexibility and
granularity provided with PowerVM virtualization provides an excellent server platform for consolidating workloads and driving server
utilization.

The Power 750 is the first RISC-based ENERGY STAR-qualified server designed with features to help become more energy efficient. When
managed by IBM Systems Director and Active Energy Manager, these Intelligent Energy features enable the POWER7 processors to operate at a
higher frequency if environmental conditions permit, for increased performance per watt. Alternatively, the server can operate at a reduced
frequency if user settings permit, for significant energy savings.
Intelligent Treads is a new technology with POWER7 and available on the Power 750 model. It provides up to 128 simultaneous compute
threads on a single server with 32 cores. Intelligent Threads technology improves application performance. Single Thread (per core) and 2 or 4
SMT (per core) modes are available. Workloads can be optimized by selecting the most suitable treading mode for particular workloads.
Intelligent Cache is also a new technology with POWER7 which maximizes cache access to cores and is available on the Power 750 server.
The Power 750 Express has all the redundant components and industry leading Reliability Availability and Serviceability (RAS) features you’ve
come to expect with previous IBM Power Systems. It is designed with capabilities to deliver leading edge application availability and allow more
work to be processed with less operational disruption. RAS capabilities include recovery from intermittent errors or failover to redundant
components, detection and reporting of failures and impending failures, as well as self-healing hardware that automatically initiates actions to
effect error correction, repair or component replacement. In addition, the Processor Instruction Retry feature provides for the continuous
monitoring of processor status with the capability to restart a processor if certain errors are detected. If required, workloads can be redirected to
alternate processors, all without disruption to application execution. The Power 750 Express implements Light Path diagnostics, which provide
an obvious and intuitive means to positively identify failing components. This allows system engineers and administrators to easily and quickly
diagnose hardware problems. Hardware failures that may have taken hours to locate and diagnose can now be detected in minutes, avoiding or
significantly reducing costly downtime. IBM Systems Director ‘Call-home’ capability enables proactive service that may result in higher system
availability and performance.

WPAR Mobility with SAN disk
WPAR Enhancements and compatibility test for Application mobility The IBM Workload Partitions Manager for AIX provides an easy, consistent way to manage Workload Partitions across an enterprise. The WPAR Manager is based on a client/server architecture in which agents on the managed systems are directed by a WPAR Manager server. The WPAR Manager agents must be installed in the global instance of each AIX 6.1 operating system image that is to be managed. The WPAR Manager enables Live Application Mobility, ability to clone or relocate a WPAR to another system without restarting the application or causing significant impact to the application users. WPARs can be relocated manually from the WPAR Manager console or automatically based on a policy that uses processor load, memory utilization and other system metrics. Live Application Mobility, which is enabled by the WPAR Manager, is designed to improve application availability and server utilization while reducing administrative workload. WPAR manager can also list the best choices of target systems when relocating a WPAR. IBM announced enhancements to the WPAR Manager and V2.1 provides significant new capabilities:
• Fully integrated into IBM Systems Director as a plug-in.
• Supports Live Application Mobility of WPARs that use SAN devices for storage.
• Significantly improved speed of Live Application Mobility operations. Live Application Mobility for WPARs with SAN devices: The SAN support for Live Application Mobility is only available for WPARs running on AIX 6.1 Technology Level 4 and later. The SAN hardware must be supported by AIX Multipath I/O (MPIO). SAN devices can be used for WPAR system and application data.
Faster Live Application Mobility for WPARs: Live Application Mobility has been significantly enhanced to provide for faster relocation operations. This enhancement can reduce the amount of time the applications are in transit and are not responding to end-user requests, in some cases to only a few seconds. Compatibility testing for Application Mobility Compatibility testing includes critical and optional tests. Each time a system is registered, the WPAR Manager starts a background process that compares the properties of the new system to the system properties of all previously registered systems. These compatibility tests help to determine if a WPAR can be relocated from one managed system to another. For each relocation type - live or static, there is a set of critical tests that must pass for one managed system to be considered compatible with another. The critical tests for static relocation are a subset of the tests for live relocation. For live relocation, the critical compatibility tests check the following compatibility criteria on the arrival system and the departure system:
• The operating system type, version and level must be the same on both the systems.
• The processor class on the arrival system must be at least as high as the processor class of the departure system.
• The version, release, modification, and fix level of the bos.rte, bos.wpars, mcr.rte filesets must be the same on both the systems.
• The bos.rte.libc file must be the same on both the systems. This is the only critical test for static relocation
• There must be at least as many storage keys on the arrival system as on the departure system. In addition to these critical tests additional optional tests can be added for determining compatibility. These optional tests are selected as part of the WPAR group policy for the WPAR planned for relocation, and are taken into account for both types of relocation. Two managed systems might be compatible for one WPAR and not for another, depending on which WPAR group the WPAR belongs to and which optional tests were selected as part of the WPAR group policy. Critical tests are always applied in determining compatibility regardless of the WPAR group to which the WPAR belongs. Optional tests to check the compatibility of arrival and departure systems:
• NTP must be enabled on both the systems.
• Physical memory on the arrival system must be at least as high as memory of the departure system.
• The processor speed for the arrival system must be at least as high as the processor speed for the departure system.
• The version, release, modification, and fix level of the xlC.rte file set must be the same on both the systems.

POWER Compatibility Modes POWER compatibility modes are designed to allow for users to migrate (think Live Partiition Mobility) from POWER6-based servers to POWER7-based servers without experiencing partition or application downtime. Migrating partitions from POWER6 to POWER7 (or n to n+1 architectures) requires that the partitions be compatible regardless of the actual hardware architecture. There is a configuration attributes for each LPAR related to POWER Compatibility Mode. On your POWER6 servers this attribute can be POWER6 or POWER6+ mode. In order to perform an LPM operation to an available POWER7 server (for F/W upgrade, maintenance, more resources, etc...) the LPM operation actually migrates the partition from POWER6 to POWER7 'maintaining' the POWER Compatibility mode. No steps need to be taken by the administrator in this scenario. HOWEVER, in order to migrate an LPAR from a POWER7 server to a POWER6 server, that compatibility mode cannot be POWER7, since the POWER6 servers cannot handle POWER7 compatibility. Changing POWER compatibility modes does require a profile change, shutdown, and subsequent reacticivation of the affected LPAR. One other item of note regarding POWER Compatibility Modes is that certain POWER7 features are ONLY available to LPAR’'s that are running in POWER7 compatibility mode. These items are (but not limited to):
• SMT4 capability - POWER6, POWER6+ compatibility modes ONLY support SMT/SMT2
• Partition Sizes > 64 Cores
• Larger (32) number of storage protection keys (8 for applications)
• Double Precision Vector Scaling (VSX)
Also, only certain versions of AIX 6.1 will run in POWER7 compatibility mode on POWER7 servers. NO versions of AIX 5.3 will run on POWER7 servers in POWER7 compatibility mode. AIX 5.3 is ONLY supported on POWER7 servers in POWER6/POWER6+ compatibility mode.
Below is a matrix of supported AIX 6.1 and AIX 5.3 versions and compatibility modes.
