History information older than seven days is automatically deleted. However, if the number of
operations exceeds 65,535, the oldest operations are deleted in chronological order to keep the
number at 65,535, even if the operations occurred within the last week. The history file always contains
the most recent operations up to a maximum of 65,535 operations. The maintenance information for an
entire week may not always be available.
The history information can be sorted by column and in ascending or descending order.
• Previous and Next buttons: The list displays up to a maximum of 16,384 operations at a time. Use
these buttons to display the previous or next 16,384 operations.
Other Operations window
Clicking the Other Operations tab displays the Other Operations window, which includes the Clear SIM

RCU operations
The RCUs are the control units that control the R-VOLs of the volume pairs. The RCUs are connected to the
MCUs through the remote copy connections and receive and process commands from the MCUs. For
TC390 operations, the secondary XP Command View Advanced Edition Software server at the remote site
should be connected to the RCUs to allow TC390 commands to be issued directly to the RCU (for example,
in case of disaster or failure at the primary site).
The MCUs are the control units which control the M-VOLs of the volume pairs. The MCUs receive and
process user-requested TC390 commands from the XP Command View Advanced Edition Software server
or XP Remote Web Console, and send the remote copy operations to the RCUs. The MCUs can also
function as RCUs, provided the remote copy connections are properly configured.
The RCU operations are performed separately for each CU image of each MCU and RCU to provide
maximum flexibility in TC390 configurations. The RCU operations are:
• Configuring the host interface ports for MCU-RCU connection (see page 83)
• Viewing RCU status (see page 85)
• Registering RCUs (see page 87)
• Setting the RCU options (see page 87)
The RCU options apply to all CU images of the MCU.
