Hitachi TrueCopy for z/OS (T1711-96009, June 2006)

66 TrueCopy for the XP1024/XP128/XP12000/XP10000
Performing TrueCopy Configuration Operations
The TC390 configuration operations include the MCU operations, RCU operations, TC390A control
operations, discontinuing TC390 operations, and scripting. The TrueCopy main window (see page 66)
provides access to all TC390 configuration operations.
RCU operations. The RCU operations (see ”RCU Operations” on page 82) configure the RCUs for TC390
operations:
• Configuring host interface ports for MCU-RCU connection
• Adding the RCUs
• Setting the RCU options
• Adding/deleting logical paths to an RCU
• Adding/deleting SSIDs for an RCU
• Viewing RCU status
• Deleting RCUs
Asynchronous operations. The TC390A control operations (see ”Asynchronous Operations” on page 102)
configure the TC390A groups and options:
• Setting the async options
• Adding consistency group
• Viewing consistency group status
• Changing the consistency group options
• Changing the async options
• Deleting consistency groups
Usage Monitor operations. Use the usage monitor operations (see page 110) to collect the I/O statistics
for the LDEVs on the disk array.
Script operations. Use the scripting function to specify and execute a series of TC390 operations without
having to issue commands separately (see ”Script Operations” on page 113).
History operations. Use the history operations (see ”History Operations” on page 113) to export the
remote copy history file.
Other operations. The other operations (see ”Other Operations” on page 113) include clearing SIMs.
You can optimize TC390 operations and XP1024/XP128/XP12000/XP10000 performance by selecting
the TC390 settings and options for your operational environment and also by addressing conditions that
can affect disk array performance. For more information, see ”Optimizing TrueCopy Operations and Disk
Array Performance” on page 113.
To discontinue TC390 operations, perform the required TC390 operations (for example, pair deletion, RCU
deletion, port reconfiguration, and so forth) in a specific order to ensure smooth operations and avoid
command rejects and error conditions. For more information, see ”Discontinuing TrueCopy Operations” on
page 115.
TrueCopy Main Window
To access any of the TrueCopy windows, click one of the following tabs: Pair Operations, RCU Operations,
Asynchronous Operations, Usage Monitor, Script Operations, History Operations, and Other Operations
tabs.
The TrueCopy main window (also known as the Pair Operations window) is displayed by clicking the Pair
Operations tab. This window shows the information for the selected CU image of the connected disk array
and provides access to all TC390 functions.
