380 Logical Partitions on System i5
򐂰 Migration of partition configuration data to HMC is not available. If HMC is deployed at a
future stage, you need to recreate the Linux partitions. The data stored through virtual I/O
on i5/OS remains unaffected.
򐂰 Initially, the Virtual Partition Manager configuration screens are only available in English
and are not translated.
򐂰 Virtual Partition Manager cannot be managed through services offerings such as LPAR
Toolkit or similar LPAR management tools provided by various IBM business partners.
Likewise, there are no Application Programming Interfaces (API) or SSH capabilities.
򐂰 You cannot use Virtual Partition Manager on an eServer System i5 system that is
configured using an HMC.
Once you have carefully understood the above planning considerations, you can start
planning for your eServer System i5 system with Linux partitions using Virtual Partition
Manager.
13.2.2 Planning for Linux logical partitions
The IBM eServer Hardware Information Center contains important information that you need
to understand as you start your preparations for deploying Linux partitions. Begin with the
“Partitioning for Linux” section:
http://publib.boulder.ibm.com/infocenter/eserver/v1r2s/en_US/index.htm?info/iphae/linuxpart
itions.htm
This section provides information about hardware requirements, logical partition planning
tasks, and details on how to create a Linux logical partition using i5/OS virtual I/O resources.
Some of the important planning steps are documented in the next section.
13.2.3 Perform capacity planning
Sizing guidelines for partitions with Linux workloads can be derived through using the IBM
Workload Estimator (WLE).
http://www-912.ibm.com/supporthome.nsf/document/16533356
WLE is a tool that runs in a Browser or on a personal computer (PC). It estimates the
computer resources required for traditional workloads as core applications and new
workloads, as Linux, WebSphere® and Lotus® workloads. For Linux, partition sizing
information is available for file serving, Web serving, and network application workloads.
Note: An IPL of eServer i5 system may be required for partition creation.
