4 Configuring Disk Storage Systems
and Logical Paths
To introduce Universal Replicator for Mainframe (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
Throughout this chapter, the primary and the secondary storage systems are sometimes referred to as
local storage systems or remote storage systems. If you are logged into the primary storage system and
are using URz, the primary storage system is a local storage system and the secondary storage system
is a remote storage system. If you are logged into the secondary storage system and are using URz,
the secondary storage system is a local storage system and the primary storage system is a remote
storage system.
When performing system configuration, the administrator also needs to configure journal groups. For
detailed information about configuring journal groups, see Chapter 5 on page 123.
DKC Operation Window
To configure storage systems and logical paths, use the DKC Operation window. For detailed instructions
on this step, please refer to XP Remote Web Console User’s Guide.
To display the DKC Operation window, do either of the following:
