Installation

Before Compaq Storage Hub 12 Management Utilities can communicate with

Compaq-managed devices, all devices must be properly configured,

connected, and powered up. Refer to the Compaq Storage Hub 12

Management Module installation instructions to configure the module for

management. Once the procedures 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 is required to communicate with HMU:

■ At least one Compaq Storage Hub 12 hub with a module

■ A 32-bit PC capable 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 through an Ethernet hub or switch running 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.

Getting Started 1-3

Software Requirements

The following software is required to install and run HMU:

■ Windows 95, Windows 98 or Windows NT installed on the 32-bit PC

that will serve as the management console. Service Pack level 3 (or

higher) is required 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.

■ The HMU Installation CD-ROM

Installation Procedure

The steps listed below should be followed when installing HMU.

If you are installing HMU for the first time

1.

Check that the display settings for your monitor are for small fonts. You

do this by clicking the Windows Start button and selecting Settings,

then Control Panel.

2.

Next click the Display icon and click the Settings tab. Finally, click on

the Advanced button. The font size is shown on the General tab of the

advanced features. Select Small Fonts if this setting is not selected.

3.

Close other Windows programs that may be running on the PC.

4.

Insert the HMU CD-ROM. (If your CD-ROM has auto-run enabled, and

the HMU setup dialog box appears, click the close button and continue

following the steps below).

5.

From the Start button, select Settings, Control Panel.

6.

Open Add/Remove Programs.

7.

Click the Install button.

8.

Follow the onscreen instructions that will execute the SETUP.EXE file.

You must acknowledge the license agreement. The application will be

installed in “C:\Program Files\Compaq\HMU” by default, unless a

different path is given.

1-4 Compaq Storage Hub 12 Management Utilities Hardware and Software User Guide

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 software. 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, it can be obtained from Adobe from their website:

www.adobe.com.

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 Hub.

■ The Compaq equipment 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 alternative path if one was named dur-

ing installation. In addition, a different path can be specified using the Log

File Configuration dialog box. This path is stored in the Window 95/98 or NT

system registry. The file’s location can not be moved without first removing

and reinstalling 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.

Getting Started 1-5

About HMU.dat

The topological data for a HMU session is stored in an archive file found 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

HMU.dat file and

discovery can be performed automatically on each IP address in the file. Once

all loops have been discovered, 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

configuration process. The following sections detail the proper way to

configure the ports.

Inter-Hub Communication Interface (ICI) ID

Numbers

As explained in Appendix A (see the “Simple Network Management Protocol”

section), while HMU may communicate with the proxy master through SNMP

over Ethernet, the proxy master communicates with its slave-managed devices

using the Compaq ICI communications protocol. 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 View “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 is 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 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.

Initial HMU Startup

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:

Getting Started 1-7

1.

Select the Start, Programs menu and click Compaq Hub

Management Utilities (if a copy of a shortcut is displayed on your

desktop, double-click it). The initial HMU screen shown in the figure

below will display. This screen will only appear when HMU is started

for the first time or after the HMU.dat file has been deleted.

Figure 1-2. Initial HMU screen

2.

Enter an IP address.

3.

Click the Discover button.

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 appears. 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 by 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

be empty if not previously entered manually.

Once discovery is complete, the Update SAN View button (shown in the lower

area of the figure below) becomes active.

Figure 1-4. Update SAN View screen

Getting Started 1-9

Click Update SAN View. When the topological update completes

successfully, the device topology is displayed. The default view is a

hierarchical representation that appears in the figure below. This is the

main menu for controlling devices with HMU.
