4 Configuring arrays and logical
paths
To introduce Continuous Access XP Journal into your system and configure your system for remote copy
operations, you must consider what data should be copied from which array to which array. The array
containing data to be copied to another array is referred to as the primary array. The array to which
data is copied from another array is referred to as the secondary array. The location of the primary array
is referred to as the primary site. The location of the secondary array is referred to as the secondary site.
When performing system configurations for remote copy operations, the primary and secondary site
administrators must do the following:
• The primary site administrator must configure some ports on the primary array to connect hosts
and configure other ports on the primary array to communicate with remote arrays.
• The secondary site administrator must configure some ports on the secondary array to
communicate with the primary array.
• After finishing the port configurations, the primary and secondary site administrators must
configure logical paths between the communications ports on the primary site and the
communication ports on the secondary site, so the two arrays can communicate with each other.
When performing system configurations, the administrators must do the following:
• Displaying the DKC Operation pane
• Configuring port attributes
• Associating primary and remote arrays and configuring logical paths (Add DKC)
When performing system configurations, the administrator should do the following when necessary:
• Changing options for logical paths and arrays
• Adding logical paths
• Deleting logical paths
• Viewing the status of logical paths
• Removing the relationship between primary and secondary arrays
NOTE:
Throughout this chapter, the primary and secondary arrays are sometimes referred to as local arrays
and remote arrays . If you are logged into the primary array and are using Continuous Access XP
Journal, the primary array is a local array and the secondary array is a remote array . If you are logged
into the secondary array and are using Continuous Access XP Journal, the secondary array is a local
array and the primary array is a remote array .
NOTE:
When performing system configurations, the administrator must also configure journal groups. For more
information, see Using journal groups .
Displaying the DKC Operation pane
To configure arrays and logical paths, use the DKC Operation pane.
