RCU Port: Port number of the RCU.
RCU S/N: Serial number of the RCU. The LD KC number is d isplayed enclosed in parentheses to
the
right of the RCU S/N.
Controller ID: Controller ID and model name.
Path Gr. ID: The user-registered path group ID when an RCU is added to use CU Free.
SSID:SSID(s) of theRCU.
RCU CU No.: CU number of the RCU. When you select CU Free, Any is displayed.
MCU-RCU Path: Type of channel interface bet ween the stora ge systems (bre or serial).
Minimum Pat hs: Minimum number of MCU-RCU paths for the selected RCU.
RIO M I H Time: Time value for the remote I/O (RIO) missing interrupt handler (MIH), which is the
wait tim e until data transfer from the MCU to RCU is co mplete.
RCU Registered: Date and time when the RCU was added.
Last Updated: Date and time when the RCU was last updated.
Round Trip Time: Delay time because of remote I/O according to the connection devices and the
distance of the line between the MCU and RCU.

Table 19 Logical Path Status
Status Description
Condition
Normal
This path has been successfully established a nd can be used for Continuous
Access remote copy activities.
Initialization Failed
The link initialization procedure with the RCU has failed because either the
physical path connection between the MCU and the RCU or the connection
between the MCU and the host was missing.
Communication Timeout
A timeout error has occurred between the MCU and RCU.
Resource Shortage
The establish logical path link function has been rejected by the RCU. All
logical path resources in th e RCU might be used for other connections.
Serial Number Mismatch
The serial number of the control unit which is connected to this lo gical path
does not match the serial number specied by the Add RCU d ialog box.
Invalid Port
The interface port specied is not in the initiator mode.
RCU Port Number
Mismatch
There are three possible factors: The specied port i n the RCU is physically
disconnected from the MCU. The port is not congured as an RCU target
port. The specied port number is not available.
RCU Port Type Mismatch
The microcode at the RCU side does not support the breremotecopy
function, or the specied port type is not an RCU target.
Communication Failed A timeout error has occurred on the path between the MCU and RCU.
Logical Blockade
This logical path was blockaded because a path error or a link error has
occurred continuously.
Program Error
This logical path was blockaded because a program error has occurred.
Deleting an RCU
You can delete an RCU from an MCU only after all Continuous Access pa irs between the MCU CU and
the
RCU CU have been released. When you delete an RCU from an MCU, the MCU deletes all l o gical
paths from the current MCU CU to the selected RCU CU. Deleting an RCU does not affect the Continuous
Access operations between the other MCU CUs and that RCU. After an RCU has been deleted, you can
