Overview
This chapter describes the overview of LPAR migration.

1-2 Overview
HVM Navigator User's Guide - Migration
LPAR migration is the function to transfer an LPAR from a server blade to
another one. You can execute LPAR migration to maintain server blades and
use resources such as CPU, memory, NIC, and FC HBA efficiently. By
executing LPAR migration, MAC address and WWN assigned to the LPAR to
migrate are transferred along with other kinds of configuration data. Then, you
can reconfigure the LPAR briefly and it’s not necessary that you reconfigure
the LPAR. In fact, two modes are supported in LPAR migration: Shutdown
mode and Concurrent Maintenance mode. You can have an LPAR migrate with
the guest OS on the LPAR running in Concurrent Maintenance mode. So, you
can exchange or update some kinds of hardware and software without
suspending services provided on the LPAR. Whereas, you can have an LPAR
migrate with the guest OS on the LPAR down in Shutdown mode. So, it’s
necessary that you shut down the guest OS in advance or you set the
shutdown option for the guest OS so that the guest OS is shut down
automatically before migration when you execute the LPAR migration.
When you execute LPAR migration in Concurrent Maintenance mode, you can
exchange or update the following kinds of hardware and software. For the
procedures, see “Exchanging or updating hardware or software” in “Migration
procedures”.

There are differences with the application requirements and kinds of
configuration data to migrate, between Shutdown mode and Concurrent
Maintenance mode. Application requirements for Shutdown mode are much
less than those for Concurrent Maintenance mode. When you have an LPAR
migrate on a server blade on a system environment for the first time, it’s
recommended that have the LPAR migrate in Shutdown mode.

Also, there are differences with kinds of configuration data to migrate or be
exchanged between Shutdown mode and Concurrent Maintenance mode. For
the kinds of configuration data to migrate or be exchanged in both Shutdown
mode and Concurrent Maintenance mode, see the following table. You can
check if each item can be set manually in the Setting column.
