7.1 Preparing for installation
There are important considerations for setting up and using IBM i 6.1 client
logical partitions on IBM Power servers or the IBM BladeCenter JS23 or JS43
Express server. On Power blades, you use the Integrated Virtualization Manager
(IVM) to manage partitions.
A
client logical partition is a partition that uses some of the I/O resources of
another partition.
When the IBM i 6.1 client logical partition is managed by Integrated Virtualization
Manager (IVM), you can assign only virtual resources to the 6.1 partition. Disk
units, optical devices, and Ethernet are accessed using virtual I/O adapters. The
Virtual I/O Server (VIOS) logical partition provides the disk, optical, and network
resources to the client logical partition. This configuration is sometimes referred
to as a pure virtual partition.
A major benefit of using virtual I/O is that you can share the hardware among the
client logical partitions through the server logical partition. This allows you to
optimize the amount of hardware used by the host partition.
7.1.1 Software installation process
The IBM i 6.1 installation process involves three phases:
Pre-installation activities
Main installation
Post-installation activities
Figure 7-1 on page 243 illustrates one type of software installation of the
IBM i 6.1 Operating System. The example this process illustrates is one of
performing an upgrade to a new release of the operating system. However, many
of the steps are similar when performing a new installation.
Note: IBM i V6R1 can be ordered pre-installed on the JS23/JS43. Use feature
code FC 8141 (IBM i pre load) and FC 8147 (VIOS Pre-load pre-req) when
ordering.
