HP 3PAR InForm OS 3.1.1 Concepts Guide

• VolSetAddr - Enables HPUX Volume Set Addressing (VSA).
• SoftInq - Enables inquiry data formats for hosts such as Egenera and NetApp.
• NACA - Enables Normal Auto Contingent Allegiance (NACA) bit for AIX.
• SESLun - Enables iSCSI Enclosure Services (SES) LUN ID 254 for Host Explorer agent support.
NOTE: Each host connected to the system must use a host persona with the iSCSI Enclosure
Services LUN (SESLun) enabled, or the Host Explorer agent cannot communicate with the system.
Table 4 (page 31) describes the specific functionality for each host persona number. For a list of
supported host operating systems, go to the Single Point of Connectivity Knowledge (SPOCK)
website http://spock.corp.hp.com/index.aspx.

NOTE: Only the Generic, Generic-ALUA, and Generic-Legacy personas are supported for iSCSI
connections.
NOTE: The NetApp host operating system requires unique WWNs for hosts in an FC fabric.
NOTE: 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 InForm Operating System 2.3.1 release, port personas were used on system ports. Port
personas are no longer supported. Use the InForm CLI commands or the InForm OS Management
Console to convert your legacy host personas to new host personas. See the InForm OS CLI
Administrator’s Manual or the InForm OS 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
