The following shows the legend for the figure in the operation procedure of this section:

Steps on the primary host (3DC Cascade (Cnt Ac-S Z x Cnt Ac-J Z) configuration)

Scan the storage system at the primary site.

Perform a scan over a range that contains volumes to be defined in the copy group and a
command device (for the forward direction) to be registered in the storage system of the
primary site.

NOTE:

In a 3DC Cascade (Cnt Ac-S Z x Cnt Ac-J Z) configuration, one storage system is

allowed for each site.

This creates the disk configuration definition file for the primary site.

For details on how to perform scans to acquire storage system information, see

“Acquiring

volume information” (page 588)

Define a path set consisting of inter-control unit logical paths (Primary

→ Intermediate) and

inter-disk controller logical paths (Intermediate

→ Remote) that are in the forward direction

(or specify a path using Remote Web Console).
