Steps on the secondary host (3DC Cascade configuration)
1.
Scan the storage system at 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 at the remote site from
the primary host.
For details on how to perform a scan to acquire storage system information, see
volume information” (page 518)
.
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).
A CU to be specified for a path set must include a volume to be defined in a Cnt Ac-S copy
group and a command device for the reverse direction.
3.
Create a route list for the reverse direction (Remote
→ Intermediate → Primary route).
