Configuring Port Attributes
The administrator at both the primary site and the secondary site must configure ports on the primary
storage system and the secondary storage system in the following ways:
•
The administrator at the primary site must configure target ports, initiator ports, and RCU target
ports on the primary storage system.
•
The administrator at the secondary site must configure initiator ports and RCU target ports on
the secondary storage system.
Ports on XP storage system have the target attribute by default. If you are configuring XP storage
systems, you must determine ports that should be used as initiator ports or RCU target ports, and
then you must change the attribute of the ports from target to initiator or RCU target. The port
attributes are explained below:
•
Target: A target port is a Fibre Channel port used for connecting a storage system and a host.
When the host issues a write request, the request will be sent to a volume via a target port on
the storage system. Target ports must be configured on primary storage systems for URz
operations.
•
Initiator: An initiator port is a Fibre Channel port that sends commands to a remote storage
system. Initiator ports must be configured on both primary and remote storage systems for URz
operations.
•
RCU target: An initiator port is a Fibre Channel port that receives commands from a remote
storage system. RCU target ports must be configured on both primary and remote storage
systems for URz operations.
•
External: An external port is a port that is required for Universal Volume Manager copy
operations. This port will not be used for URz copy operations.
If necessary, you can change this port to an target port, an initiator port, or an RCU target
port.
•
Initiator/external: This setting shows the combination of ports that have an initiator port and
an external port attributes. Only port that has an initiator port attribute within these ports can
be used for URz. This attribute cannot be changed by the URz software. For details on the
port to which an initiator/external mix mode is set, see the External Storage Software user
guide.
