Reviewing Administrator Tasks for Managing Journals
To introduce Universal Replicator for Mainframe 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 Universal Replicator for Mainframe 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 Universal Replicator for Mainframe 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
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 Universal Replicator for Mainframe, 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 Universal Replicator for Mainframe, the
secondary storage system is a local storage system and the primary storage system is a remote
storage system.
