issue simultaneous processing requests to an DevMgr Agent or BCM Agent associated with an
information source, there is a possibility for errors during DevMgr Agent or BCM Agent processing.
In such configurations where Replication Manager is to be set up on both the local (operating) site
and remote (standby) site in order to prepare for disaster recovery, HP recommends that the status of
Replication Manager server on the standby site be set to maintenance mode. If the status is not set to
maintenance mode, an error might occur on either the operating site or the standby site, when
Replication Manager instances on the both of these sites attempt to perform operations simultaneously
on the information source.
When Replication Manager handles multiple prefixes
(mainframe systems)
Replication Manager allows you to confirm, define and operate copy pairs for multiple prefixes
concurrently. On the Hosts or Storage Systems view you can confirm DEVNs and LDEVs without
specifying or identifying the prefix. During pair configuration, Replication Manager prohibits selection
of P-VOLs / S-VOLs from multiple prefixes on a mainframe host.
To avoid conflicts when managing multiple prefixes, Replication Manager does not allow volumes
that were already scanned and stored to the disk configuration definition file to be added as the
volume range. When a volume scanned by multiple prefixes is discovered, Replication Manager
displays the prefixes in the Hosts view, allowing you to identify duplication of prefixes.
