5-2 Chapter 5 Configuring Storage Systems and Logical Paths
Hitachi Universal Replicator for IBM /OS User’s Guide
Reviewing Storage System and Logical Paths
To introduce Universal Replicator for z/OS (henceforth abbreviated as URz)
into your system and configure your system for remote copy operations, you
must consider which data should be copied from which storage system to
which storage system. The storage system containing data to be copied to
another storage system is referred to as the primary storage system. The
storage system to which data are copied from another storage system is
referred to as the secondary storage system. The place where the primary
storage system exists is referred to as the primary site. The place where the
secondary storage system exists is referred to as the secondary site.
When performing system configurations for remote copy operations, the
primary site administrator and the secondary site administrator must do the
following:
• The primary site administrator must configure some of the ports on the
primary storage system to connect hosts. The primary site administrator
must also configure some other ports on the primary storage system to
communicate with remote storage systems.
• The secondary site administrator must configure some ports on the
secondary storage system to communicate with the primary storage
system.
• After finishing port configurations, the primary and secondary site
administrators must configure logical paths between the communication
ports on the primary site and the communication ports on the secondary
site, so that the two storage systems can communicate with each other.
When performing system configurations, the administrators must do the
following:
• Display the DKC Operation window
• Configure port attributes
• Associate the primary and the secondary storage systems and configure
logical paths between the two storage systems
When performing system configurations, the administrator should do the
following when necessary:
• Change options for logical paths and storage systems
• Add logical paths
• Delete logical paths
• Displaying status of logical paths
• Delete the relationship between the primary and the secondary storage
systems
