5 Ports and Hosts
Overview
The HP 3PAR storage system sees a host as a set of initiator port WWNs (World Wide Names)
or iSCSI Names. Hosts that are physically connected to ports on the system are automatically
detected. The Fibre Channel port WWNs and iSCSI port iSCSI Names are displayed by the user
interfaces. You can also add new WWNs or iSCSI Names for unestablished host paths and assign
them to a host before they are physically connected. These WWNs or iSCSI Names do not need
to be associated with target ports on the system controller nodes. This allows for plug-and-play
functionality that avoids the need for manual reconfiguration after connecting new hosts. For
instructions on modifying system ports and host configurations, see the HP 3PAR Command Line
Interface Administrator's Manual and HP 3PAR Management Console Online Help.
Fibre Channel over Ethernet (FCoE) connectivity is supported on HP 3PAR StoreServ 10000 Storage
systems and HP 3PAR StoreServ 7000 Storage systems through the use of Converged Network
Adapters (CNA). CNA ports can be configured to be used as FCoE or iSCSI ports.
A virtual volume can be exported, or made accessible, to one or more hosts. The host sees the
exported virtual volume as a LUN connected to one or more ports. Once the virtual volume is
exported to a host, the host can send requests to the LUN. See
more information about virtual volumes and exporting virtual volumes. For instructions on exporting
virtual volumes, see the HP 3PAR Command Line Interface Administrator's Manual and HP 3PAR
Management Console Online Help.
Persistent ports (also known as virtual ports) allow HP 3PAR storage system host-facing ports to
assume the identity of partner ports that are automatically designated by the system. For Fibre
Channel and Fibre Channel over Ethernet (FCoE) ports, this is achieved through the use of N_Port
ID Virtualization (NPIV). For more information about persistent ports and NPIV, see the HP 3PAR
Command Line Interface Administrator's Manual.
NOTE:
See the HP 3PAR Implementation Guides for recommended practices and detailed
configuration information about using your specific host devices with the system.
About Ports
System controller nodes can use Fibre Channel, Gigabit Ethernet, iSCSI, and Serial Attached SCSI
(SAS) , and Fibre Channel over Ethernet (FCoE) ports to connect the storage system to your network,
host computers, storage system components, and to other systems. You can use the HP 3PAR CLI
and the HP 3PAR Management Console to view port information and modify port settings. For
instructions on viewing and modifying port configurations, see the HP 3PAR Command Line Interface
Administrator's Manual and HP 3PAR Management Console Online Help.
Fibre Channel Ports
Systems use Fibre Channel ports to connect controller nodes to hosts and drive cages and
drive enclosures. On HP 3PAR StoreServ 7000 Storage systems, FC ports are designated for
host connection and Remote Copy use only. For information about controller nodes and drive
cages, see
iSCSI Ports
Systems use iSCSI ports to connect controller nodes to hosts. For information about controller
nodes, see
