Journal
1
Prerequisite software for XP Continuous Access Journal must be
installed and the license must be enabled.
There must be a fibre-channel connection between the two ports
used for an MCU-RCU path
2
The MCU port for an MCU-RCU path must be an Initiator port, and
the RCU port must be an RCU Target port
2
The RCU and the MCU-RCU path must be registered in the MCU
2
The storage subsystem cache or nonvolatile memory must be
sufficient.
Journal volumes must be registered in the journal group.
NOTE: After configuring the ports, you need to refresh the storage
subsystem. If you need to increase the cache, contact maintenance
personnel.

For mainframe volume copy pairs, the only operation you can perform with Device Manager is to check
the configuration. To check the copy pair configuration by using Device Manager, there are no storage
subsystem requirements.

The settings specified in XP Continuous Access Software can be shared with XP Continuous Access
Journal. However, in XP Continuous Access Journal, the settings must be specified for both storage
subsystems used for the P-VOL and the S-VOL.
1-7-4 Notes on using Device Manager when XP RAID
Manager is already managing copy pairs
If a copy pair is already managed by XP RAID Manager, the copy pair can be managed by Device
Manager once Device Manager is installed.
Note the following if you are using XP RAID Manager to manage existing copy pairs:
If you want to use Device Manager to control copy pairs managed by XP RAID Manager, the
configuration definition file on the host that manages the P-VOL of the copy pair and the
configuration definition file on the host that manages the S-VOL of the copy pair must have the
same group name and the same pair name. If different names are specified, Device Manager
cannot control that copy pair. In addition, if you want to use a single host to manage multiple
