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.

For information about using Global Mirror on IBM System Storage DS8000®, see Copy Services in the IBM System Storage DS8000 Information Center.
For information about using Global Mirror with SAN Volume Controller (SVC) or Storwize® storage devices, see IBM SAN Volume Controller Information Center.
