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 (see “DKC Operation Window” (page 93) )
•
Configure port attributes (see “Configuring Port Attributes” (page 99) )
•
Associate the primary and the secondary storage systems and configure logical paths between
the two storage systems (see
Establishing the Relationship between Primary and Secondary
Storage Systems (Add DKC) )
When performing system configurations, the administrator should do the following when necessary:
•
Change options for logical paths and storage systems (see Changing Options for Logical Paths
and Storage Systems )
•
Add logical paths (see Adding Logical Paths )
•
Delete logical paths (see Deleting Logical Paths )
•
Displaying status of logical paths (see Viewing the Status of Logical Paths )
•
Delete the relationship between the primary and the secondary storage systems (see Removing
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
“Using Journal Groups” (page 110) .
DKC Operation Window
To configure storage systems and logical paths, use the DKC Operation window. For detailed
instructions on this step, see the XP Remote Web Console user's guide.
