5Configurin g Storage Systems and
Logical Paths
Reviewing S ystem Configuration Tasks
To introduce Continuous Access Journal into your system and configure your system for remote copy
operations, you must consider which data s hould be co pied from which storage system to which storage
system. The storage system containing the data to b e copied to another storage system is referred to as
the
primary storage system. The storage system to which data is copied from another storage system
is
referred to as the secondar y storage system. The plac e where the primary storage system exists is
referred to as the primary site. The place where the secondary storage system exists is referre d 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 por ts on the p rimary storage system
to
connect hosts. The primary site adm inistrator must also con figure other p orts on the p rimary
storage system to com municate 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 the port configurations, the primary and secondary site administrators must
configure logical paths between the communications ports on the primary site and the
communications ports on the secondary site, so that the two storage systems can communicate
with each other.
When per forming system config urations, the adm inistrators must do the following:
•
Display the DKC Operation window (see “DKC Operation Window”onpage85)
•
Configure port at tributes (see “Configuring Port Attributes” on page 96)
• 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)” on page 98)
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 Pa ths and Storage Systems” on page 101)
•
Add logical paths (see “Adding Logical Paths”onpage102)
•
Delete lo g ical paths (see “D eleting Logical Paths”onpage105)
•
Display status of log ical p a ths (see “Viewing the Status of Logical Paths” on page 103)
• Delete the relationship between the p rimary and the secondary storage systems (see
“Removing the Relationship Between the Primary and the Seconda ry Storag e Systems” on page 108)
Note
: 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 Continuous Access Journal, the primary storage system is a local storage system a nd the
secondary storage system is a remote storage system. If you are logged into the secondar y storage
system and a re using Continuous Access Journal, the secondary storage system is a local storage system
and
the primary storage system is a remote storage system.
Note
: When performing system configurations, the a dm inistrator a lso needs to con fi gure journal groups.
For detailed information about con figuring journal groups, see “Using Journal Groups” on page 111.
