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, aswell asports 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 (i.e., 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
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 storagesystem and theprimary storage system isa remote
storage system.
