4Conﬁguring 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.
