1.1 HP 3PAR Host Explorer

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

Storage system. The Host Explorer is an agent that runs as a service on Windows and as a

daemon on Linux and Solaris operating systems. No license is required to use the HP 3PAR Host

Explorer.

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

enables the host to send detailed host configuration information to the storage system. The

information gathered from the Host Explorer is visible for uncreated hosts and assists with host

creation and diagnosing host connectivity issues.

TpdHostAgent, which allows

Introduction

1.1

HP 3PAR Host Explorer User Guide

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

to the storage system. Without the Host Explorer running on the attached hosts, the storage

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 running, the storage

system automatically groups WWNs or iSCSI names for the host together, assisting with

creating the host.

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

■ Host operating system and version.

■ Fibre Channel and iSCSI HBA details.

■ Multipath driver and current multipath configuration.

■ Cluster configuration information.

■ Device and path Information.

See Chapter 2, Installation and Deinstallation to install the HP 3PAR Host Explorer.

Refer to the HP 3PAR OS Configuration Matrix for a list of supported host operating systems.
