System configuration for analyzing the performance of Continuous Access Journal
To analyze the performance of Continuous Access Journal, either an open system that is configured
to manage Continuous Access Journal copy groups or an open system that uses Performance Advisor
is required.
Before the management client can connect to the Device Manager servers at the primary and secondary
sites, all of the following conditions must be satisfied:
• The Performance Advisor server is installed at the same site as the Device Manager server that is
connected from the management client (the site on the Replication tab side).
• Replication Manager at the site not on the Replication tab side is in maintenance mode.
Figure 17 Example of a system that has a management server and a management client (and that is
configured to analyze performance by connecting to the Device Manager server at the primary site)
NOTE:
To move the management server environment to a new machine, you must perform the procedure for
handing over the collected performance information. If you do not perform the procedure correctly,
the collected performance information might be lost. For details, see HP XP7 Command View Advanced
Edition Release Notes .
TIP:
If the following operations are performed, the history information of C/T Delta and journal volume
