•
RCU Registered: Date and time when the RCU was added.
•
Last Updated: Date and time when the RCU was last updated.
•
FREEZE Option: Support for the CGROUP (FREEZE/ RUN) PPRC TSO command.
•
Round Trip Time: Delay time because of remote I/O according to the connection devices and
the distance of line between MCU and RCU.

RCU Operation window after closing the RCU Status dialog box, click check box. By default,
the check box is not selected.
The Refresh button refreshes the status information. The Close button closes the RCU Status dialog
box.
Table 43 Logical Path Status
Condition Status Description
This path has been successfully established and can be
used for TrueCopy for Mainframe remote copy activities. Normal
The link initialization procedure with the RCU has failed,
because either the physical path connection between the Initialization Failed
MCU and the RCU or the connection between the MCU
and the host was missing.
A timeout error has occurred between the MCU and RCU. Communication Timeout
The establish logical path link function has been rejected
by the RCU. All logical path resources in the RCU might
be used for other connections. Resource Shortage
The serial number of the control unit which is connected to
this logical path does not match the serial number specified
by the Add RCU dialog box. Serial Number Mismatch
The interface port specified is not in the initiator mode. Invalid Port
There are three possible factors: The specified port in the
RCU is physically disconnected from the MCU. The port is RCU Port Number Mismatch
not configured as an RCU target port. The specified port
number is not available.
The microcode at the RCU side does not support the fibre
remote copy function. Or the specified port type is not RCU
target. RCU Port Type Mismatch
A timeout error has occurred on the fibre path between
MCU and RCU. Communication Failed
This logical path was blockaded because a path error or
a link error had occurred continuously. Logical Blockade
This logical path was blockaded because a program error
had occurred. Program Error
Deleting an RCU
You can delete an RCU from an MCU only after all TrueCopy for Mainframe pairs between the
MCU CU and RCU CU have been released. When you delete an RCU from an MCU, the MCU
deletes all logical paths from the current MCU CU to the selected RCU CU. Deleting an RCU does
not affect the TrueCopy for Mainframe operations between the other MCU CUs and that RCU.
After an RCU has been deleted, you can reconfigure the remote copy connections to add another
RCU to the MCU, or you can remove the remote copy connections and reconfigure the MCU ports
(initiator ports to ordinary target ports for fibre) to provide additional host channels for the MCU.
