CAUTION:
When an MCU and RCU are connected via switches with a channel extender and multiple remote
copy paths are assembled, the majority of data to be transmitted might be concentrated on particular
switches, depending on the switch routing's configuration and settings.
Enabling Continuous Access XP Journal options
To operate Continuous Access XP Journal, a management station is required for Command View
XP. For more information about Command View XP or XP Remote Web Console operations, see
the HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks
XP Remote Web Console user guide for XP12000/XP10000/SVS200 or contact your HP account
support representative.
Planning for journal volumes
The data transfer speed for journal groups is affected by the journal volume specifications the journal
groups use. Therefore, to achieve the desired data transfer speed, you must consider these journal
volume specifications.
Considerations
This section explains what you need to consider when deciding on journal volume specifications.
