6-2 Chapter 6 Configuring Journal Groups
Hitachi Universal Replicator for IBM /OS User’s Guide
Reviewing Administrator Tasks for Managing Journals
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 (i.e., the primary and the secondary data volumes)
from mirrors
• Delete journal groups from an extended consistency group forcibly
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 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.
