to the storage system. The information gathered from the Host Explorer agent is visible to uncreated
hosts, and assists with creating hosts and diagnosing host-connectivity issues.
How Host Explorer Helps You Create Hosts
When you create a host, the system displays the unassigned WWNs or iSCSI names:
• When the Host Explorer agent is running on the attached hosts, the system automatically
groups the WWNs or iSCSI names for the host together, which helps you create the host.
• If the Host Explorer agent is not running on the attached hosts, the system cannot determine
which host each WWN or iSCSI name belongs to, and you must manually assign each WWN
or iSCSI name to a host.
How Host Explorer Helps You Diagnose Host-Connectivity Issues
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
