Installation
Before Compaq Storage Hub 12 Management Utilities can communicate with
Compaq-ma naged devices, all devices must be properly configured,
connected, and powered up. Refer to the Compaq Storage Hub 12
Management Module instal l ation instructions to configure the modul e for
management. Once the pr ocedures have been completed, verify that the
hardware and software requirements (listed below) are met, and then perform
the HMU installation procedure
Hardware Requirements
The following hardware i s required to communicate w i th HMU:
■ At least one Compaq Storage Hub 12 hub with a module
continued
.
■ A 32-bit PC c apable of running Windows 95, Windows 98 or Windows
NT 4.0
■ An Ethernet connection from the management PC to the managed
device. This can be throu gh an Ethernet hub or switch r unning 10
Base T
IMPORTANT: While it may be possible to run HMU on a system that is also a server, we
do not recommend that you do so; it is possible for the two applications to interfere with
each other. Run HMU on its own dedicated workstation.
Software Requirements
The following software is required to install and run HMU:
■ Windows 95, Windows 98 or Windows NT installed on the 32-bi t PC
that will serve as the management console. Service Pack level 3 (or
higher) is re quired on Windows NT 4.0.
IMPORTANT: If the program is running under Windows 95, you should have a version of
COMCTL32.DLL no older than 5/19/97 and you should have winsock2.dll installed. Earlier
versions do not contain support for the common controls that are used in HMU. These
updates are available from the Microsoft support area at www.microsoft.com.

NOTE: If you see a "Read Only File Detected" message during the installation process,
answer "Yes."
In addition, an Acrobat PDF version of this guide will be installed in the same
directory as the HMU softwar e. To load the PDF file, you must have a copy of
the Acrobat Exchange program. If you do not already have this program on
your system, i t can be obtained from Adobe from their website:
When successfully installed, the Compaq icon will appear in your Program
list.
NOTE: Right-click HMU.exe and select Create Shortcut to create a shortcut that
displays on your desktop.
Configuring HMU for Your Site
Before starting HMU installation:
■ A Compaq-managed proxy master must be connected to your Ethernet
network.
■ The Compaq Hub 12 Management Module must be installed in the
Compaq Storage Hub 12 Hu b.
www.adobe.com.
■ The Compaq e quipment chosen to be a proxy master must be connected
to the LAN with an Ethernet connection, and must have proxy master
set in its network parameters.
About HMU.log
Event information is displayed during each HMU session and is saved in
HMU.log on shutdown. By default, the path to HMU.log is “C:\Program
Files\Compaq\HMU\HMU.log,” or an alter native path if one was named during installation. In addition, a different path can be specified using the Log
File Config uration dialog box. This path is stored in t he Window 95/98 or NT
system registry. The file’s location can not be moved wi thout first removing
and reinstal ling HMU.
You can configure HMU to overwrite a single log file at the start of each
session or to write a file to the limit size and then create another log. If the
HMU.log file is deleted, a new one will be created the next time HMU is
started. You can also view the HMU.log file from a spreadsheet program such
as Microsoft Excel since that program uses the comma-separated-variable
(csv) format.
About HMU.dat
The topological data for a HMU session is stored in an archive file fou nd on
the default path, “C:\Program Files\Compaq\HMU\HMU.dat”, or at an
alternative path if one was entered during installation. The IP address for the
proxy management agent for each loop and the user-entered data for
unmanaged devices are always written to this file whenever HMU is shut
down, or when the Save Topological Data command is selected. When HMU
is started the next time, this data is retrieved from the
discovery can be performed automatically on each IP address in the file. Once
all loops have been discove red, the unmanaged devices for the loops are added
to the views.
NOTE: Keep the HMU.dat file backed up if more than one loop is being managed in the
event unmanaged devices are added to a hub. Data can be saved at any time.
Understanding Port Relationships
The relationship between the ports in HMU is an essential part of the
configurat i on process. The following sections detail the proper wa y to
configure the ports.
Getting Started 1-5
HMU.dat file and
Inter-Hub Communication Interface (ICI) ID
Numbers
As explained in Appendix A (see the “Sim ple Network Management Protocol”
section), while HMU may communicate with the proxy master through SNMP
over Ethernet, the proxy master communi cates with its slave-managed devices
using the Compaq ICI communications pr otocol. As a result, the various
devices are assigned an ICI ID number. You can view these numbers on each
individual managed device by looking at the Device V iew “System ID Tab”
(see Chapter 3, “Managing from Device View” for specific information about
device view activities).
The device agent, designated as the HMU management agent, is assigned an
ICI ID1. The first managed slave added to the network i s numbered ICI ID2
and the next managed slave is assigned ICI ID3. These numbers are
sequentially assigned as managed devices are added.
1-6 Compaq Storage Hub 12 Management Utilities Hardware and Software User Guide
Downlink and Uplink Ports
The Downlink and Uplink Ports are defined by the physical cabling tha t exists
between devi ces in the management hierarchy. Downli nk Ports or Parent Ports
are ports on the higher level devices to which a device lower in the hi erarchy
is attached. These can appear in both proxy masters as well as cascaded
devices. Uplink Ports or C hi ld Ports are the port numbers on the lower-l evel
device that attachment is made to.
The figure below shows a sample SAN configuration that illustrates the
relationships between ports.

Initial HMU Startup
The first time HMU is started, the IP address of a Compaq-managed proxy
master devic e at your site must be entered. I f 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 pro xy master is to be managed.

The next part of the process is to verify the SNMP and to set Community
Names. If the Community Names are still set to the defaults, HMU will
continue with discovery.
NOTE: The default get Community Name is “public”, while the default set Community
Name is “private”. If these do not work, check with a system administrator who can give
you the current Community Names. To set Community Names, see Appendix C,
“Configuring the Management Module.”
1-8 Compaq Storage Hub 12 Management Utilities Hardware and Software User Guide
The discovery process can take several seconds, during which time the HMU
progress status indicator a ppears. It will indicate which device it is polling, so
if there is more than one, there will be changes in progress. It will normally
time out in 60 seconds, but if it appears to be taking too long, click on Cancel
to stop it. Wait at least 60 seconds before canceling. The first time HMU is
started, allow the system to time out, in order to get a better idea of how long
to wait in the future if a problem occurs.
Figure 1-3. Progress status indicator
The discovery process establishes communication links with the proxy master.
Other managed devices connected to the proxy master b y Fibre Channel are
found automatically. The Device Name, Location, Contact, Serial Number,
and Device Count fields are filled in, but the Location and Contact fields will

in HMU. These are:
The SAN View tab of HMU’ s GUI is the main window for keeping
a.
track of the overall status of your networ k. Two buttons on it display
the status of all of the devices either graphically in the View Devices
by Connection window or in a tabular format with the View
Devices by Name window. The Context Menu is available in both
of these windows. This menu gives access to other windows that
offer further information and diagnostic functions.
Display Network View is one of the sets of windows accessed from
b.
the Context Menu. It contains four tab pages that pres ent network
status on an individual device level. The s e tab pages all ow the
monitoring of traffic levels on the network as well as the activity of
various FC-AL (Fibre Channel Arbitrated Loop) primitive s. I n
addition, there are a number of additional control functions.
The Event Log tab is the second tab on HMU’s GUI window.
c.
Clicking on it displays a log of events that have occurred since the
last time HMU was started.

Display Device View is an intuitive GUI interface that presents the
d.
same information noted above but in a completely graphical
representation of the fr ont panel of the hub.
Control functions: HM U contains a ful l suite of control functions.
2.
These functions are located in one of three locations:
The Context Menu - As noted, one of the items on the Context
a.
Menu is the Display Network View tab pages. One of its tabs,
Network Configuration , permits control of the Polling Rate, Retry
Count, and Timeout period of SNMP polling as well as enabling the
user to set the Trap Management station’s IP address.
Device View - This GUI interface also permits you to set and reset
b.
some of the parameters controlled by the Context menu. These are
discussed in the next chapter.
File Menu - Clicking File at the top of the main window opens a
c.
menu that gives access to several important including configuring
the log file and deleting events. This menu sets these parameters
across the ent ire monitored ne twork. This menu is discussed later in
this chapter.
Compaq Storage Hub 12 Diagnostic Tools Fault Diagnosis and
3.
Resolution: Finally, the DisplayNetwork View tab pages also contain
two separate fault diagnostics. The first is Loop Utilization Alert and the
other is Diagnostic Tools. Selections in these pages i nclude the
following:
■ Set Utilization Alert Percentage - This feature permits the setting
of the network utilization rate to the point at which an alarm is
sounded. The default value is a 90 percent utilization, but it can be
increased or decreased easily.
■ Diagnostic Tools - This is a set of aut omatic diagnostic and repair
tools that initiates the following two diagnostics:
q
Loop Initialization Diagnostic - This d iag nostic will appear
whenever one or more devices are unable to initialize properly.
The tool continues to restart the initialization process. The
diagnostic will determine which devices are at fault, isolate
them, and identify them.
q
Broadcast Storm D iagnostic – This is related to the Loop
Initialization diagnostic. Broadcast Storm Diagnostic will hunt
down and isolate any devic e that is broadcasting a c ontinuous
stream of LIP(F7,x) or other primitives.
SAN View Tab
The SAN View Devices by Connection window (shown in Figure 2-1) is the
first display that appears once the discovery process a nd topologica l updates
are completed. It presents a graphical presentation of the overal l network, a nd
also permits access to all the other features of HMU. The SAN View tab is the
main window of HMU.
At the top, the managed master device acting as the proxy master displa ys its
IP address. T he managed an d unmanaged slave devices display a port
identifier that is the Downlink Port number of the parent device to which it is
attached. The status of Inter-Hub Communication Interface (ICI) devices is
represented by the color of their icons as listed below.

■ Green represents normal status.
■ Yellow indicates a change in status, such as a port being automatically
bypassed.
■ Red indicates a critical or major fault, such as a power supply,
temperature, fan fault, or loss of communication with the device.

The two push buttons near t he top of the HMU window toggle between the
default hierarchical view and the View Devices by Name window, shown in
the Figure 2-2.
Figure 2-2. SAN View tab- View devices by name
In this display, the devices are sorted alphabetically. The Status column
indicates one of the following: Normal, Minor, Maj or, Warning, Critical, and
Not Managed. Both views display ICI-co nnected devices that can be managed,
in addition to any unmanaged devices t hat have been manually added to a
network.
The Context Menu
Most HMU activities can be accomplished from the HMU Context Menu.
This menu is selected by right clicking on either of the SAN View tab
windows. Specific features and functions of the Context Menu depend upon
which wind ow and type of device are highlighted.
For example, if the hub repre s entation is right clicked, the HMU Context
Menu shown in Figure 2-3 appears. In this case, the user is only permitted to
perform act i ons that are related to adding, deleting, discovering devices and
more.

If the mouse is moved to one of the icons representing a device and right
clicked, the description of that device c hanges to white lettering on a blue field
and a differ ent version of t he Context menu appears. Thi s menu reflects the
control functions available in that device alone, as shown in the figure below.
In the illustration, the proxy master hub has been selected, and as a result,
several funct ions are enabl ed. Other devic es in the network might have fewer
choices enabled, but each menu is appropriate for the device selected.

Display Device View
The first item in the Context Menu is Display Device View, which selects the
Device View GUI interface.
Display Network View
Clicking this item selects a set of four tab windows that display a wealth of
information about the functioning of the SAN. Some of these tabs allow
control of specific functions and parameters as well.
Network Status Tab
The first tab, shown in the figure below, is the Network Stat us tab. This tab
displays inf ormation in a table format.

Summary infor mation appears across the top of the window. This includes t he
status of the loop, as well as information about initialization. The little icon
near the top shows the network status in color and with a nearby text message.
The colors of the icon are the same as used in the SAN View tab page.
Below, the status of each port on each managed device in the network appears,
showing one port per line. This informat ion includes the number of t he device
the port is o n, the port number and status of that port as well as the numbe r of
LIPs that have occurred. This information is particula rly useful whe n
determining devices that display atypical behavior . Additional information
includes the AL_PA of the device that port is connected to (if there is one), as
well as Loop ID. The Device name may also appear if it is a managed device.
