2.1 The 3PAR Host Explorer
The 3PAR Host Explorer is a program that runs on a host connected to an InServ Storage Server.
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 3PAR Host Explorer.
The Host Explorer communicates with the storage server over an FC or iSCSI connection and
enables the host to send detailed host configuration information to the storage server. The
information gathered from the Host Explorer is visible for uncreated hosts and assists with host
creation and diagnosing host connectivity issues.
When a host is created on the InServ Storage Server, unassigned WWNs or iSCSI names are
presented to the storage server. Without the Host Explorer’s running on the attached hosts,
the storage server 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 Explorers running, the
InServ Storage Server 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 server:
■ Host operating system and version.
