The Host Explorer Software Agent The HP 3PAR Host Explorer Software agent is a program that runs on a host connected to an HP storage system. The Host Explorer agent runs as a service on Windows and as a daemon on Linux and Solaris operating systems. No license is required to use the Host Explorer agent. The Host Explorer agent communicates with the system over an FC or iSCSI connection and enables the host to send detailed host configuration information to the system. The information gathered from the Host Explorer agent is visible for uncreated hosts and assists with host creation and diagnosing host connectivity issues. When a host is created on the system, unassigned WWNs or iSCSI names are presented to the system. Without the Host Explorer agent running on the attached hosts, the system is unable to determine which host the WWN or iSCSI names belongs to and you must manually assign each WWN or iSCSI name to a host. With Host Explorer agents running, the system automatically groups WWNs or iSCSI names for the host together, assisting with creating the host. The Host Explorer agent collects the following information and sends it to the system: • Host operating system and version. • Fibre Channel and iSCSI HBA details. • Multipath driver and current multipath configuration. • Cluster configuration information. You can install the Host Explorer agent from the HP 3PAR Host Explorer CD. For instructions on installing and using the Host Explorer agent, see the HP 3PAR Host Explorer User's Guide.

NetApp ONTAP

SubLun, ALUA

Linux and Windows

VMware

NOTE:

•

Only the Generic, Generic-ALUA, and Generic-Legacy personas are supported for iSCSI

connections.

•

The NetApp host operating system requires unique WWNs for hosts in an FC fabric.

•

A host device must use either iSCSI or Fibre Channel connections. Mixed ports on a single

device is not supported.

Legacy Host Personas

A legacy host persona is a host persona that simulates the behavior of a port persona. Prior to the

HP 3PAR Operating System 2.3.1 release, port personas were used on system ports. Port personas

are no longer supported. Use the HP 3PAR CLI commands or the HP 3PAR Management Console

to convert your legacy host personas to new host personas. See the

HP 3PAR Command Line

Interface Administrator’s Manual

or the HP 3PAR Management Console Online Help for instructions

on converting your legacy host personas.

The Host Explorer Software Agent

The HP 3PAR Host Explorer Software agent is a program that runs on a host connected to an HP

storage system. The Host Explorer agent runs as a service on Windows and as a daemon on Linux

and Solaris operating systems. No license is required to use the Host Explorer agent.

The Host Explorer agent communicates with the system over an FC or iSCSI connection and enables

the host to send detailed host configuration information to the system. The information gathered

from the Host Explorer agent is visible for uncreated hosts and assists with host creation and

diagnosing host connectivity issues.

When a host is created on the system, unassigned WWNs or iSCSI names are presented to the

system. Without the Host Explorer agent running on the attached hosts, the system is unable to

determine which host the WWN or iSCSI names belongs to and you must manually assign each

WWN or iSCSI name to a host. With Host Explorer agents running, the system automatically

groups WWNs or iSCSI names for the host together, assisting with creating the host.

The Host Explorer agent collects the following information and sends it to the system:

•

Host operating system and version.

•

Fibre Channel and iSCSI HBA details.

•

Multipath driver and current multipath configuration.

•

Cluster configuration information.

You can install the Host Explorer agent from the

HP 3PAR Host Explorer

CD. For instructions on

installing and using the Host Explorer agent, see the

HP 3PAR Host Explorer User’s Guide

. For a

list of supported host operating systems, go to the Single Point of Connectivity Knowledge (SPOCK)
