Global Mirror options and
configuration
In this chapter we provide a detailed description of Global Mirror options, including how to
create a Global Mirror environment and how to remove it. We discuss how to change Global
Mirror tuning parameters and how to modify an active Global Mirror session. We also discuss
a scenario where a sites switch is performed due to a primary site failure.
The information discussed in this chapter can be complemented with the following IBM

Global Mirror is intended for long distance data replication. For this, it relies on the network
infrastructure and components used between the remote sites. This chapter does not cover
network related topics. For information on these topics, refer to IBM TotalStorage Business
Continuity Solutions Guide, SG24-6547.
