Overview of Configuration Operations
The XP Continuous Access configuration operations include RCU operations, asynchronous
operations, usage monitor, history, optimizing operations, and discontinuing operations.
• RCU operations. The “RCU Operations” (page 86) configure the following RCUs for TrueCopy
operations:
◦ Configuring the host interface ports for MCU-RCU connection
◦ Adding an RCU
◦ Setting the RCU options
◦ Adding/deleting logical paths to an RCU
◦ Adding/deleting IDs for an RCU
◦ Viewing RCU status
◦ Deleting an RCU
• Asynchronous operations. The “Asynchronous Operations” (page 102) configure the following
XP Continuous Access Asynchronous consistency groups and options:
◦ Setting the async options
◦ Adding consistency groups
◦ Viewing consistency group status
◦ Changing the consistency group options
◦ Changing the async options
◦ Deleting consistency groups
• Usage Monitor operations. The “Usage Monitor Operations” (page 109) enable you to see the
I/O statistics for the LDEVs on the storage system.
• History. The “History Operations” (page 113) enable you to export the remote copy history
file.
• Optimizing XP Continuous Access operations. See “Optimizing XP Continuous Access
Operations and Storage System Performance” (page 117) for information on optimizing XP
Continuous Access operations and XP24000/XP20000 Disk Array performance by selecting
