Mapping a Command Device as a Remote Command Device

Using TrueCopy or Universal Replicator with Remote
Command Device
When you want to use TrueCopy or Universal Replicator with a remote
command device, you need two different kinds of ports, which are an initiator
port for TrueCopy or Universal Replicator and an external port for the remote
command device. However, if you set the Initiator/External MIX mode, you will
be able to use a port as both initiator port for TrueCopy or Universal Replicator
and external port only for the remote command device.
Before you set the Initiator/External MIX mode, you need to prepare initiator
ports and external ports in one port block of the Standard mode. You can set
the Initiator/External MIX mode on the port block that consists of the initiator
ports and external ports.
Figure 7-2 shows difference between the Standard mode and Initiator/External
MIX mode. When the Standard mode is set to the ports, you have to connect
the cables for both initiator port and external port. However, if you set the
Initiator/External MIX mode, you just need to connect one cable, and you can
use TrueCopy or Universal Replicator and remote command device.
For detailed information on the port block and setting the Initiator/External
MIX mode, see the LUN Manager User's Guide.
