Flow of configuration definitions (2DC configuration)
This section explains the flow of a 2DC configuration definition both with and without a host at
the secondary site.
Secondary site with a host
When a host is installed at the secondary site, you can perform a local scan at that site to acquire
the volumeinformation of that site.
Figure 75 (page 130) shows the process flow for defining a 2DC configuration with a host at the
secondary site. The step numbers indicated in Figure 75 (page 130) corresponds to the procedures
in “Definition procedure (2DC configuration)” (page 131).
