382 Logical Partitions on System i5
13.3.1 Minimum configuration requirements
The following requirements apply for Linux partitions created on an eServer i5 system. Each
partition requires the following components:
򐂰 Processor unit:
– 0.10 processing units allocated out of a shared processing pool
򐂰 Memory:
– A minimum of 128MB of memory or region size (whichever is largest) is needed.
– Hypervisor memory set aside from your total memory capacity—available for
managing logical partitions. Your Logical Partition Validation Tool (LVT) gives you an
indication of this memory requirement. For more information, see the memory section
in the Information Center at the following Web address.

򐂰 Disk storage:
– 1GB served through Virtual I/O by i5/OS
򐂰 Network interface:
– One virtual Ethernet adapter for communicating to i5/OS or other Linux partitions
򐂰 Partition management console:
– iSeries Operations Console, LAN Console or 5250 (Twinaxial) Console for partition
creation and management
򐂰 Software requirements:
– i5/OS V5R3 or above
– Minimum of 2.3.0 version firmware applied. For information about minimum software
requirements, and download instructions, visit the IBM eServer Prerequisite Web-site

Select the Software tab with the options shown as Figure 13-1.
– Ensure that you have a minimum of PTF MF34753 (or its supersede) applied to enable
Virtual Partition Manager. If this PTF is not already installed, please download and
apply them before starting your partition setup.
– Prerequisite PTFs MF34946 and MF34962 must be permanently applied before doing
a SAVSYS of the i5/OS partition. A D-mode IPL of the Virtual Partition Manager
activated i5/OS partition will fail with an SRC of A6005001 with media that does not
have these PTFs permanently applied.
Note: These minimum configurations may vary significantly depending on the workload
enabled for each of the Linux partitions, and based on the Linux distribution and version
that you install. Please refer to a specific Linux distribution's guideline for the actual values.
