Configuring disk arrays and logical paths
To introduce Continuous Access XP Journal into your system and configure your system for remote copy
operations, consider what data should be copied from which disk array to which disk array. The disk array
containing data to be copied to another disk array is referred to as the primary disk array. The disk array
to which data is copied from another disk array is referred to as the secondary disk array. The location of
the primary disk array is referred to as the primary site. The location of the secondary disk 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 disk array to connect hosts
and configure other ports on the primary disk array to communicate with remote disk arrays.
• The secondary site administrator must configure some ports on the secondary disk array to
communicate with the primary disk 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 disk arrays can communicate with each other.
When performing system configurations, the administrators must do the following:
• ” Displaying the DKC Operation pane ” on page 75
• ” Configuring port attributes ” on page 79
• ” Associating primary and remote disk arrays and configuring logical paths (Add DKC) ” on page 80
When performing system configurations, the administrator should do the following when necessary:
• ” Changing options for logical paths and disk arrays ” on page 82
• ” Adding logical paths ” on page 83
• ” Deleting logical paths ” on page 85
• ” Viewing the status of logical paths ” on page 85
• ” Removing the relationship between primary and secondary disk arrays ” on page 87
NOTE: Throughout this chapter, the primary and secondary disk arrays are sometimes referred to as local
and remote disk arrays. If you are logged into the primary disk array and are using Continuous Access XP
Journal, the primary disk array is a local disk array and the secondary disk array is a remote disk array. If
you are logged into the secondary disk array and are using Continuous Access XP Journal, the secondary
disk array is a local disk array and the primary disk array is a remote disk array.
NOTE: When performing system configuration, the administrator must also configure journal groups. For
more information about configuring journal groups, see ” Using journal groups ” on page 88.
Displaying the DKC Operation pane
To configure disk arrays and logical paths, use the DKC Operation pane.
