This page provides a graphical representation of controller host port status and port
details.
2. Review the graphical representation of host port status.

■ A faulty Ethernet cable
■ A faulty port in the host interface module
■ A disconnected cable
3. To target the cause of the link failure, view the host port details by clicking on a
port in the graphical view and then reviewing the details listed below it.
The data displayed includes:
■ iSCSI Port Status Details – Selected controller and port number

■ IP Version – IP addressing version; 4 for IPv4
