Overview
3PAR InForm CLI Administrator’s Manual 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 in the InForm CLI. 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.
Host personas are a set of behaviors that permit hosts connected to FC or iSCSI ports on the
InServ Storage Server to deviate from the default host behavior. By assigning a persona to a
host, multiple host types that require distinct customized responses can share a single InServ
Storage Server port. For example, hosts running Windows, Linux, and AIX operating systems
can all connect to the same InServ port. This simplifies connecting hosts to the storage server
and reduces management time related to complex host connections.
For more information about ports, hosts, and host personas, see the InForm OS Concepts
Guide.
6.2 Modifying Port Parameters
Use the InForm CLI controlport command to modify the Fibre Channel (FC) ports and the
Gigabit Ethernet ports used for the 3PAR Remote Copy over IP (RCIP) solution. Use the
controliscsiport command to modify the iSCSI ports on the InServ Storage Server. These
commands control several aspects of the ports. Whenever you use these commands, you must
use a sub-command specifying the operation you want to perform and include the port
location.
The InForm CLI displays the controller node Fibre Channel, iSCSI, and Gigabit Ethernet port
locations in the following format:
<Node>:<Slot>:<Port>. For example: 2:4:1.
NOTE: See the 3PAR Implementation Guides for recommended practices and
detailed configuration information about using your specific host devices with
the InServ Storage Server.
