Configuring ALOM

This chapter provides help on some basic configuration tasks including:

ALOM Configuration Steps

Your ALOM software comes preinstalled on your host server, so it works as soon as you apply power to the server. You can connect a terminal to the serial management port (SERIAL MGT) and immediately start working with ALOM.

However, if you want to customize ALOM for your installation, you must perform some basic tasks.

Here are the tasks you must complete to customize ALOM:

1. Plan how to customize your configuration. Refer to Planning Your ALOM Configuration for more information.

2. Use the configuration worksheet to record your settings. Refer to Configuration Variable Worksheet.

3. Run the setupsc command. Refer to Setting Up ALOM.

4. Use the configuration variables to customize the ALOM software. See To Use Configuration Variables in the ALOM Command Shell.

Explanations of the listed tasks follow.

Planning Your ALOM Configuration

ALOM software comes preinstalled on your host server. Follow the directions in this section to reinstall or update ALOM.

Note - Refer to your system administration guide to find the location of the serial and Ethernet connections for ALOM.

Before you run the setupsc command to set up ALOM, you must decide how you want ALOM to manage your host server. You need to make the following decisions about your configuration:

Once you make those decisions, print the configuration worksheet shown in Configuration Variable Worksheet, and use it to record your responses to the setupsc command.

Choosing ALOM Communication Ports

The ALOM hardware contains two types of communication ports:

Both ports give you access to the ALOM command shell. By default, ALOM communicates through the SERIAL MGT port at startup.

Note - Refer to your system administration guide to find the location of the server's serial management and network management (Ethernet) connections.

Serial Management Port

You can connect to the ALOM serial management port with an ASCII terminal or terminal emulator (such as a serial connection from a workstation).

This port is not an all-purpose serial port; it is a dedicated port used to access ALOM and the server console through ALOM.

On your server, this port is referred to as the SERIAL MGT port. This port takes a standard RJ-45 connector.

Ensure that your console serial port is set to the following parameters:

The host server automatically sets these parameters for ALOM when it starts up. The settings are read-only, and cannot be changed from the ALOM sc> prompt. To view the settings for the parameters from the sc> prompt after you establish an ALOM session, check the serial port variables. Refer to Serial Management Port Variables for more information.

1. Connect to ALOM.

See Connecting to ALOM and Logging In to Your ALOM Account for detailed instructions on establishing an ALOM system controller session.

The ALOM shell prompt (sc>) is displayed.

2. To connect to the system console, in the ALOM system controller window type:

sc> console

3. To return to the ALOM shell prompt (sc>) type the escape sequence (Pound- Period):

sc> #.

Network Management (Ethernet) Port

The 10/100-Mbit Ethernet port enables you to access ALOM from within your company network. You can connect to ALOM remotely using any standard Telnet client with TCP/IP (Transmission Control Protocol/Internet Protocol). On your server, the ALOM Ethernet port is referred to as the NET MGT port.

Note - When you connect a terminal device to the NET MGT port, the server must be connected to a 10-Mbit or 100-Mbit network. ALOM does not support 1-Gbit networks.

Configuration Worksheet

You only need to use this worksheet if you want to customize ALOM for your installation.

To customize ALOM, you use the configuration variables. Refer to Using ALOM Configuration Variables for details of variables.

There are two ways to set up the configuration variables for ALOM:

Print this section and use the table to record your inputs. This table can also serve as your record of the host server configuration in case you need to reinstall the server software or modify the ALOM settings.

Make sure that your terminal device is connected to ALOM before you customize the ALOM software. Choosing ALOM Communication Ports details the process.

Configuring Your Network Using DHCP

There are two ways to configure Dynamic Host Configuration Protocol (DHCP) for ALOM:

Note - It is a best practice to set the ALOM device name associated with the Internet Protocol (IP) address in name server maps (network information service [NIS] or domain name system [DNS]) to be the name of the host server with -sc appended to it. For example, if your host server's name is bert, the ALOM device name is bert-sc.

If you use DHCP to control your network configuration, configure the DHCP server to assign a fixed IP address to ALOM.

Configuring Your Network Manually

There are two ways to manually configure the network for ALOM:

If you set each variable individually, you need to set the following variables:

Configuring Email Alerts

To send email alerts, the ALOM Ethernet port must be enabled, (see Network Management (Ethernet) Port).

When a problem occurs, ALOM sends an alert message to all users who are logged in to ALOM accounts on that server. In addition, you can configure ALOM to send alerts by email to users who are not logged in. When a user receives an alert, that user can connect to the ALOM account for that host server and address the alert condition.

The ALOM software permits you to set up to eight unique email addresses to receive alerts. You can configure each email address to receive its own severity level of alerts (critical, major, or minor). Refer to Sending and Receiving Alert Messages.

Setting Up ALOM

After you have finished planning your configuration, run the setupsc command described on setupsc. Follow the prompts on the screen to customize the ALOM software for your installation.

Note - You do not have to customize the ALOM software before you can use it. The ALOM software works as soon as you connect power to the server.

The setupsc command runs a script that steps you through each ALOM function that you can customize. Each function is associated with one or more configuration variables. For more on configuration variables, refer to Chapter 6. To configure a function, type y when the setupsc script prompts you to do so. To skip a function, type n.

If you later need to change a setting, run the setsc command as described on setlocator Command Options.

Customizing the ALOM Software

The setupsc script enables you to set up a number of configuration variables at once. See Chapter 6 for more information. If you want to change one or more configuration variables without running the setupsc script, use the setsc command as shown on To Use the setsc Command.
