Hitachi TrueCopy for z/OS user guide (December 2005)

60 TrueCopy for the XP128/XP1024/XP10000/XP12000
Usage Monitor operations. Use the usage monitor operations (see page 104) 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 107).
History operations. Use the history operations (see ”History Operations” on page 107) to export the
remote copy history file.
Other operations. The other operations (see ”Other Operations” on page 107) include clearing SIMs.
You can optimize TC390 operations and XP128/XP1024/XP10000/XP12000 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 107.
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 109.
