Bidirectional ports must be set up on the primary and secondary systems for TrueCopy command and data transfer.
- The number of hosts connected to a Target port must be limited to 128 or fewer to avoid disconnection.
- If you are changing a Target port to a Bidirectional port, prepare the port for the change as follows:
- Confirm that the port is offline.
- Disconnect the port from the host.
- Remove all channel paths to the port.
- If you are changing a Fibre channel port
or iSCSI port from a Bidirectional port to a Target port, prepare the port for the change as follows:
- Release all pairs using the ports.
- Delete the paths from the Bidirectional port to the remote storage system.
- Disconnect the connection from the local storage system to the remote storage system. See Deleting remote connections.
- Change the attribute of the Fibre Channel port from Bidirectional to Target by using the CCI raidcom modify port command.
- Confirm that the port attribute is changed to Target by using the CCI raidcom get port command.
