• Tree: Lists channel adapters and ports on the local array.
• List: Displays ports on the local array.
• Port: Port number.
• Attribute: Port attribute (initiator, target, RCU target, external, or initiator/external).
• PCB Mode: Port mode. The mode is either Standard, High, or MIX.
• CU#: Currently, displays nothing.
• Error Code: Error code.
Configuring port attributes
The administrator at the primary and secondary sites must configure ports on the primary and secondary
arrays in the following ways:
• The administrator at the primary site must configure target ports, initiator ports, and RCU target ports
on the primary array.
• The administrator at the secondary site must configure initiator ports and RCU target ports on the
secondary array.
Ports on the array have the target attribute by default. If you are configuring an array, determine which
ports should be initiator or RCU target ports, and change the ports’ attributes from target to initiator or
RCU target.
• Target: A target port is a Fibre Channel port used to connect an array and a host. When the host issues
a write request, the request is sent to a volume through a target port on the array. You must configure
target ports on primary arrays for Continuous Access XP Journal operations.
• Initiator: An initiator port is a Fibre Channel port that sends commands to a remote array. You must
configure initiator ports on primary and remote arrays for Continuous Access XP Journal operations.
• RCU target: An initiator port is a Fibre Channel port that receives commands from a remote array. You
must configure RCU target ports on primary and remote arrays for Continuous Access XP Journal
operations.
• External: An external port is a port that is required for External Storage XP copy operations. This port
is not used for Continuous Access XP Journal copy operations.
If necessary, you can change this port to a target, initiator, or RCU target port.
• Initiator/external: A port with a combination of initiator and external port attributes. You can use a
port with this attribute for both Continuous Access XP Journal and for external storage remote
command devices. You cannot change this attribute using the Continuous Access XP Journal GUI. For
more information about ports with the Initiator/External MIX attribute, see the HP StorageWorks
External Storage XP user guide.
NOTE: If initiator and RCU target ports are not configured on the primary and remote arrays, the
following problems occur and remote copy operations are not performed:
• The administrator at the primary site cannot create pairs for primary and secondary volumes.
