5 Using Journal Groups
To introduce URz in your system and configure your system for remote copy operations, the primary
site administrator and the secondary site administrator must configure journal groups, as well as
ports and logical paths. Also, these administrators must register journal volumes in journal groups.
During URz remote copy operations, data in primary data volumes are copied via journal volumes
to secondary data volumes.
When configuring journal groups, the administrators must do the following:
•
Display the Journal Operation window
•
Register journal volumes in journal groups
When configuring journal groups, the administrator should do the following when necessary:
•
Delete journal volumes from journal groups
•
View detailed information about journal groups
•
Change journal group options
•
Delete journal groups
When URz is used for remote copy operations, the administrator should do the following when
necessary:
•
Split mirrors
•
Restore mirrors
•
Delete data volumes (that is, the primary and the secondary data volumes) from mirrors
•
Delete journal groups from an extended consistency group forcibly
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 URz, the primary storage system is a 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.
Displaying the Journal Operation Window
To configure journal groups, use the Journal Operation window of URz.
