RCU Path Parameters
For fibre-channel interface, two types of PCB mode settings are provided:
Standard and High. Therefore, when you configure paths among the initiator
ports, target ports, and RCU target ports, please study the port modes and
specify the correct mode for each port. For details on the relationship between
ports and PCB modes and instructions for setting the PCB mode, please refer
to the LUN Manager User’s Guide (MK-96RD615). Figure 5-2 shows a sample
TrueCopy for z/OS fibre-channel interface configuration with connections going
through switches and the TrueCopy for z/OS Add RCU window used to define
this configuration.
