Figure 81 Process flow for defining a 2DC configuration with a host at the secondary site
#1 This procedure is not required if the path has been established using Remote Web Console.
#2 A logical path must be built for the reverse direction if you are:
•
Using Continuous Access Journal Z
•
Using the Reverse Resync Function
•
Operating the primary site storage systems from the secondary site by using the Remote DKC
Control Function.
#3 This procedure is not required if you do not operate the primary site storage systems from the
secondary site by using the Remote DKC Control Function. However, if the Continuous Access
Synchronous Z Consistency Preservation Function is used at the secondary site, a command device
is required at the secondary site.
NOTE: To operate the primary site storage systems at the secondary site, you need to transfer
the configuration files created at the primary site to the secondary site.
Secondary site without a host
When a host is not installed at the secondary site, you can perform a remote scan from the primary
site to acquire volume information of the secondary site. You do not need to transfer the configuration
files from the primary site to the secondary site.
