Plan and define the following Fibre Channel port attributes for TrueCopy:
- Target port: Connects the storage system and a host. When the host issues a write request, the request is sent to a volume on the system through a target port on the storage system.
- Bidirectional port: Connects the remote copy and external storage systems as a Initiator port or a Target port. This port has the following three kinds of port attributes. The host server connections can be shared through the port set as Bidirectional, however this is not recommend for improving performance.
- Initiator ports, which send data. One initiator port can be connected to a maximum of 64 RCU target ports. Configure initiator ports on both the primary and secondary systems for TrueCopy disaster recovery operations.
- RCU target ports, which receive data. Configure RCU target ports on both the primary and secondary systems for TrueCopy disaster recovery operations.
- External port: Required for Universal Volume Manager copy operations. This port is not used for TrueCopy copy operations.
