Definition procedure (4x4x4 Cascade)
Basically, a 4x4x4 Cascade configuration is defined with the following procedure.
1. Set up the storage system.
Set the items that need to be set by using Remote Web Console from among the items listed
in Table 62 (page 204).
2. Set up a Business Continuity Manager environment.
Do the following:
• Perform a Local Scan on the storage system at each site, and transfer the disk configuration
definition file containing the scan results of each site to all other sites.
• On each site, define a path set and establish a logical path.
• On each site, define a route list and register a command device.
3. Create copy groups.
On the primary site, define copy groups, create copy pairs, and register the copy pair in the
EXCTG of the storage system.
