Configuring Global Mirror
For IBM® i
high availability solutions that use IBM System Storage® Global
Mirror technology, you need to configure a session between the IBM i machine and IBM System
Storage external storage units that have Global Mirror configured.
In IBM i, Global Mirror sessions
do not set up the mirroring on the external storage units, but rather
sets up a relationship between the IBM i
systems and the existing Global Mirror configuration on external storage
units. 
Before creating a Global Mirror
session on IBM i, you should
have configured Global Mirror on the IBM System Storage external
storage units.
