9. Perform a remote scan of the storage systems of the remote sites:
Perform a scan over a range that contains volumes to be defined in the copy group.
For details on how to perform a scan to acquire storage system information, see “Acquiring
volume information” (page 430).
Steps on the Secondary Host (3DC Cascade Configuration)
1. Scan the storage system on the remote site:
• Perform a scan over a range that contains volumes to be defined in the copy group and
a command device (for the reverse direction) to be registered in the storage system of
the remote site.
• A DAD ID assigned by a scan (Local Device Address Domain ID in the Set Defaults panel)
must be the same DAD ID assigned by performing a remote scan on the remote site from
the primary host.
For details on how to perform a scan to acquire storage system information, see “Acquiring
volume information” (page 430).
2. Define a path set consisting of inter-CU logical paths (Intermediate -> Primary) and inter-DKC
logical paths (Remote -> Intermediate) that are in the reverse direction (or specify a path using
Remote Web Console).
