When an HMC is connected to the OpenPower 710 server, the OpenPower 710 integrated
service processor communications ports are disabled. An async adapter is required to
provide serial connections if required.
Older HMC models, such as the 7315-CR2 or 7315-C03 and others, can be upgraded to
support POWER5 processor-based systems.
To upgrade an existing POWER4 HMC:
Order FC 0961 for your existing HMC. Contact your IBM Sales Representative for help.
Call an IBM Service Center and order APAR MB00691.
Order the CD online by selecting Version 4.4 machine code updates → Order CD →
Go at the Hardware Management Console Support Web page at:
https://techsupport.services.ibm.com/server/hmc/power5
Note: You must have an IBM ID to use this freely available service. Registration
information and an online registration form can be found at the above Web page.

2.8.4 LPAR validation tool
When configuring dynamic or virtual partitions on POWER5 systems, the LPAR Validation
Tool (LVT) can be used to verify system resource requirements. With the LVT, you can
customize the partition design by selecting PCI slots for given adapters, specific drives to
selected bays, and much more. The LVT provides a useful report that can complement the
organization and validation of features required for configuration of a complex partition
solution. The LVT supports IBM Eserver p5 and IBM Eserver i5 servers, iSeries™, and
OpenPower systems. A proficient knowledge of LPAR design requirements, limitations, and
best practice, facilities the use of this tool.
The LVT tool provides the following functions:
Support for partitions running Linux
Validation of dynamic LPAR design
Validation of virtual partition design, including Virtual I/O Server and virtual clients
Calculates unallocated memory and shared processor pool
Calculates Hypervisor memory requirements
