Downlink and Uplink Ports

Initial HMU Startup

The Downlink and Uplink Ports are defined by the physical cabling that exists
between devices in the management hierarchy. Downlink Ports or Parent Ports
are ports on the higher level devices to which a device lower in the hierarchy
is attached. These can appear in both proxy masters as well as cascaded
devices. Uplink Ports or Child Ports are the port numbers on the lower-level
device that attachment is made to.
The figure below shows a sample SAN configuration that illustrates the
relationships between ports.

The first time HMU is started, the IP address of a Compaq-managed proxy
master device at your site must be entered. If you do not have that address,
check with a system administrator so that you have it before launching HMU.
Thereafter, that IP address will be stored in a file in the default path,
"C:\Program Files\Compaq\HMU\", or at an alternative path if one was
entered during installation. It will not need to be entered again unless it
changes or a different proxy master is to be managed.
The initial starting sequence is as follows:
