4Conﬁguring Disk Storage Systems

and Logical Paths

To introduce Universal Replicator for Mainframe (henceforth abbreviated as URz)intoyour systemand

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 ﬁ nishing 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

areusing URz, theprimary storage system isa 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 c

onﬁgure storage systems and logical paths, use the DKC Operation window. For detailed instructions

this step, please refer to XP Remote Web Console User’s Guide.

To display the DKC Operation window, do either of the following:
