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 FC connections. Mixed ports are not supported on a single
device.

The Host Explorer Software Agent

The HP 3PAR Host Explorer Software agent is a program that runs on a host connected to a 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 HP 3PAR 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 agents 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.
FC 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 HP SPOCK website:
http://www.hp.com/storage/spock
To display the information returned by the Host Explorer agent to the system, issue the showhost
-agent or showhost -agent -d command.

Hosts and Virtual Domains

NOTE: Virtual domains requires the use of the HP 3PAR Virtual Domain Software license. Contact
your local HP representative for details.
If you are using virtual domains, you can create and modify domain-specific FC or iSCSI hosts. In
many instances, you follow the same process for creating and modifying hosts as you would for
hosts that do not use domains.
