Overview
3PAR InForm OS Concepts Guide InForm OS Version 2.3.1
6.1 Overview
The InServ Storage Server 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 InServ Storage Server 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 storage server controller
nodes. This allows for plug-and-play functionality that avoids the need for manual
reconfiguration after connecting new hosts. For instructions on modifying InServ Storage
Server ports and host configurations, see the InForm OS CLI Administrator’s Manual and
InForm OS Management Console Online Help.
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 Chapter 10, Virtual Volumes for
more information about virtual volumes and exporting virtual volumes. For instructions on
exporting virtual volumes, see the InForm OS CLI Administrator’s Manual and InForm OS
Management Console Online Help.
6.2 About Ports
InServ Storage Server controller nodes can use Fibre Channel, Gigabit Ethernet, and iSCSI ports
to connect the storage sever to your network, host computers, storage sever components, and
to other storage servers. You can use the InForm CLI and the InForm Management Console to
view port information and modify port settings. For instructions on viewing and modifying
port configurations, see the InForm OS CLI Administrator’s Manual and InForm OS
Management Console Online Help.
NOTE: See the 3PAR Implementation Guides for recommended practices and
detailed configuration information about using your specific host devices with
the InServ Storage Server.
