8-4 Troubleshooting
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
Table 8-2 Troubleshooting RCU Path Status Problems (continued)
Path Status Description Corrective Action
RCU Port
Number
Mismatch
The specified port in the RCU is
physically disconnected from
the MCU.
Make sure that you entered the correct RCU port number.
Correct the port number if necessary.
Make sure that the MCU and RCU are physically connected.
For fibre-channel interface, make sure that the fibre-channel topology
settings of the MCU and RCU ports are correct.
RCU Port Type
Mismatch
The specified port in the RCU is
not configured as an RCU
Target port.
Make sure that the port in the RCU configured as an RCU
target port. Configure the port as an RCU target port if
necessary.
Communication
failed.
The MCU connects to the RCU
successfully, but logical
communication time out
occurred.
Make sure that the RCU port and remote copy connection
hardware (cables and switches) are properly configured and
functioning.
Port Number
Mismatch
The specified port number is
not correct, or the cable is not
connected to the specified port.
Delete the error path.
Make sure that you entered the correct port number.
Make sure that the cable is connected.
Communication
Error
Communication between the
MCU and RCU through the fibre
path timed out.
Delete the failed path.
MCU Port does not work. Repair the port status on the MCU.
RCU Port does not work.
Repair the port status on the RCU. And then delete the path
with “Edit Path” or “Delete RCU”, and add the path again with
“Edit Path” or “Add RCU”.
The path relay equipment does
not work.
Repair the path relay equipment. And then delete the path with
“Edit Path” or “Delete RCU”, and add the path again with “Edit
Path” or “Add RCU”.
Logical Blockade
The connection cable is
physically broken .
Replace the broken cable. And then delete the path with “Edit
Path” or “Delete RCU”, and add the path again with “Edit Path”
or “Add RCU”.
Program Error Program error is detected. Delete the path with “Edit Path” or “Delete RCU”, and add the
path again with “Edit Path” or “Add RCU”.
<blank> This path was not established.
Delete the failed path. You may need to change the minimum
paths setting or delete the RCU in order to delete the path.
Then add the path/RCU using Edit Path or Add RCU.
