Table 5-3 Logical Path Status
Status Description Condition
Normal This path has been successfully established and can be used for TCz 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
the RCU might be used for other connections.
Serial Number
Mismatch
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.
Invalid Port The interface port specified is not in the initiator mode.
RCU Port Number
Mismatch
There are three possible factors: The specified port in the RCU is physically disconnected from
the MCU. The port is not configured as an RCU target port. The specified port number is not
available.
RCU Port Type
Mismatch
The microprogram at the RCU side does not support the fibre remote copy function. Or the
specified port type is not RCU target.
Communication
Failed
A timeout error has occurred on the fibre path between MCU and RCU.
Logical Blockade This logical path was blockaded because a path error or a link error had occurred continuously.
Program Error This logical path was blockaded because a program error had occurred.
