After completing the hardware installation procedures in the previous section, you must install and configure the RAC software. This section provides information on installing and configuring the RAC software. For more information on the RAC software components, see "Software Components."
If you are adding a RAC (DRAC III or ERA/O) to an existing managed system, it is recommended that you update the system's BIOS before installing the RAC to ensure full support for the card. (ERA is embedded in the system and a BIOS update is not necessary.) In addition, you must ensure that the SNMP service is installed and properly configured before installing the software on the managed system. The following sections provide procedures for updating the BIOS and for adding and configuring the SNMP service.
- Obtain a copy of the most current version of your system's BIOS.
Updates are available on the Dell | Support website at support.dell.com.
- Launch the executable file and follow the prompts to create a BIOS flash
diskette.
- Insert the BIOS flash diskette into the managed system's diskette drive and reboot the
system.
The system boots to the BIOS update menu.
- Follow the instructions on the BIOS update menu.
The SNMP service allows the managed system's software to communicate with the RAC. If the operating system on the managed system was installed using the Server Assistant CD (or System Support CD for 64-bit systems), the SNMP service may already be configured. However, if it is not, you must add and configure the SNMP service before installing the RAC software on the managed system.
 |
NOTE: If you add the SNMP service after you apply the Microsoft service pack, you
must reinstall the current service pack and possibly the appropriate video drivers.

|
- Configure SNMP with proper community names by loading inetcfg.
If SNMP is not properly configured, you cannot log in successfully and configure the RAC.
The following is a sample SNMP Config line contained in netinfo.cfg:
load snmp MonitorCommunity=public ControlCommunity=public
TrapCommunity=public
Before installing the RAC software on a Red Hat Linux 7.1 or later managed system, you must first install the ucd-snmp package using the following command:
rpm -ivh ucd-snmp
The following provides a high-level overview of the RAC software installation and configuration process. Some steps give you the option of using several different tools to perform the configuration, including Server Administrator, IT Assistant, and the racadm utility. Those procedures that can be performed using your operating system utilities are included in this section.
Depending on the tool used to perform the configuration, you will need to reference the following documents for more information:
- Server Administrator — see your Server Administrator User's Guide.
- IT Assistant — see your IT Assistant User's Guide.
- Racadm command-line utility — see "racadm Utility."
To install and configure your RAC software, perform the following steps:
- If necessary, update the BIOS on the managed system.
See "Updating the System BIOS."
- If necessary, add and configure the SNMP service.
See "Adding and Configuring the SNMP Service," and "Adding and Configuring the SNMP Service for Windows® 2000 Managed Systems."
- Install the software on the managed system using the Systems Management CD (32-bit
systems) or the Server Management CD (64-bit systems).
For instructions on installing this software, see your Server Administrator User's Guide.
The managed system has the following components embedded or installed: a RAC, the appropriate version of Server Administrator, and the appropriate RAC agent. Depending on the operating system, the RAC agent consists of either Windows services, Novell NLMs, or Red Hat Linux drivers and daemons. The RAC agent automatically starts when you boot the managed system.
|
NOTE: If it becomes necessary to reinstall or upgrade the Server Administrator on the
managed system, you must first uninstall the RAC software on the managed system. This
software uses a library file provided by the Server Administrator. If you reinstall Server
Administrator and the RAC is using the library file, the installation may fail.
|
- If necessary, install (or upgrade) the software on the management station, including
Server Administrator and IT Assistant, using the Systems Management CD (32-bit
systems) or the Server Management CD (64-bit systems).
For instructions on installing this software, see your Server Administrator User's Guide.
A management station is a system (typically a workstation running Windows NT or Windows 2000) that has the following components installed: appropriate versions of Server Administrator (or IT Assistant), a supported browser (Internet Explorer 5.x, Netscape Navigator 6.x or later), Windows services (if applicable), Server Administrator (or IT Assistant) services, and user interface elements.
- If you are installing on a managed system (not a management station) running
Windows NT, continue with this step; otherwise, proceed to step 6.
On a managed system running Windows NT, you must first create a PPP connection (modem) manually and then add that modem to the RAS. Follow the instructions in "Configuring PPP On a Managed System Running Windows NT" and then continue with step 6.
- Add and configure the RAS on the managed system and the management station
using one of the following tools.
|
NOTE: If you are installing on a managed system running Windows NT, you must use the
operating system utilities to configure RAS.
|

For security purposes, the DRAC III supports two types of users: DRAC III users and DRAC III dial-in users. Additionally, demand dial-out entries are configured with management station user information.
- DRAC III users – DRAC III users can establish console redirection and perform configuration and management actions on the DRAC III.
- DRAC III dial-in users – Also called Point-to-point protocol (PPP) users, dial-in user names and passwords are used to establish a dial-in connection only. After the connection is established, a DRAC III user name and password must be supplied in order to perform console redirection, configuration, and management actions.
- Demand dial-out entries – Demand dial-out entries specify a destination IP address, the telephone number of a management station, a management station user name and password, and the authentication type associated with the management station user name and password.
|
NOTE: The entries are not DRAC III users. Rather, they are remote management station
users.
|
|
NOTE: It is not necessary for the destination IP address to be the remote management
station that answers the telephone. The destination IP address may be the IP address of
another remote management station. If the destination IP address is the IP address of
another remote management station, the management station answering the telephone must
be able to route to the destination IP address specified.
|
Some of the DRAC III features are configured within the context of a DRAC III user, such as alerting and paging. The following sections describe how to configure the DRAC III features and/or users outside the Server Administrator environment.
To provide client access to the managed system's DRAC III, you must add and configure dial-in (PPP) users. For information on configuring these users in Server Administrator, see your Server Administrator User's Guide. For information on configuring these users in IT Assistant, see your IT Assistant User's Guide. For information on configuring these users through the racadm utility, see "racadm Utility." Otherwise, use the procedures in the following sections to add and configure dial-in users.
|
NOTE: If for any reason all the DRAC III users are deleted, use the racadm utility to
create new users.
|
If a dial-in client with a Microsoft operating system has a NIC IP address on the same subnetwork as the DRAC III PPP dial-in addresses (whether by DHCP, static configuration, or default configuration), the dial-in network connections between the client NIC address and the DRAC III NIC address operate in an unexpected manner, or do not operate at all. This behavior is limited to network connections initiated by a Microsoft client to the DRAC III local dial-in IP address.
|
NOTE: The DRAC III Managed Node PPP Server uses the 192.168.0.0 network to
communicate with the installed DRAC III.
|
Specifically, if you want to dial into a DRAC III from a Microsoft client, you must ensure that:
- If using DRAC III static configuration, configure the DRAC III dial-in base address to be on a different subnetwork from the client NIC.
- If using DHCP, ensure that the DHCP server does not assign the client NIC and DRAC III dial-in addresses on the same subnetwork.
- If using the DRAC III autogenerated address, ensure that the client NIC is not on the 10.0.0.0 private internetwork.
For instructions on changing the PPP server IP address on the managed system, see the following section.
To change the managed system's PPP server IP address to use another network, use the racadm utility according to the following sample entry:
racadm config -g cfgRacTune -o cfgRacTuneMnNwIpAddrBase
<new_ip>
where <new_ip> is the IP address of the new network.
For more information on using the racadm utility, see "racadm Utility."

- To test whether your PPP daemon supports the callback protocol, open a command
shell and issue the following command:
pppd callback 1111
If your PPP daemon is not properly configured, it generates an error message about the callback option.
- After verifying that your PPP daemon is configured with callback support, you must
set up the proper chat scripts for your environment.
An example modem setup is described at
www-cache.mppmu.mpg.de/callback/linuxanalog.html.
- Create the file /etc/ppp/peers/rac with the following contents:
tty02 crtcts 38400
connect `chat –v –f /etc/ppp/chat/rac'
noipdefault
nodefaultroute
lock
user <username>
remotename <rac>
where <username> is the DRAC III user name that is supplied to the DRAC III, and <rac> is the name preferred for the DRAC III.
- Create the file /etc/ppp/chat/rac with the following contents, where the actual
telephone number replaces 555-1212.
This chat script assumes a modem with a standard AT command set and may need to be modified if the actual modem does not support this command set:
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO ANSWER"
ABORT "BUSY"
"" "at"
OK "at&d2&d1"
OK "atdt555-1212"
- Edit the /etc/ppp/chap-secrets file (which lists PPP users and passwords) to include
the DRAC III PPP user.
Using the following example as a guideline, add a single line to the file.
|
NOTE: The <username> and <rac> values in the following example must match the
<username> and <rac> values placed in the /etc/ppp/peers/rac file in the previous step.
|
# client server secret IP addresses
<username> <rac> <password> *
where <password> is the password that is supplied to the DRAC III during the authentication phase of PPP negotiation.
|
NOTE: The IP address value (indicated by the * symbol in the previous example) is not
used when acting as a PPP client.
|
For DRAC III dial-out alert notifications, a single SMTP server may be specified for e-mail reception, with up to eight SNMP trap daemon destinations that can be specified. If the IP address of the SMTP server, or any of the SNMP trap daemon addresses, is specified in a demand dial-out entry, the DRAC III dials the telephone number specified in the demand dial-out entry to deliver an e-mail or SNMP trap to that address. Otherwise, if the IP address of the SMTP server, or any of the SNMP trap daemon addresses is not specified in a demand dial-out entry, the remote access DRAC III NIC is used to deliver the e-mail or SNMP trap to that address.
To support the dial-out notification feature on the DRAC III, the management station must allow for dial-in. See the following sections for instructions on configuring dial-out alert notifications.
To configure your Windows NT management station so that the DRAC III can establish a connection and log an alert, perform the fol-lowing steps:
- At the management station, click the Start button, point to Programs®
Administrative Tools, and then click User Manager.
- From the User menu, select New User.

Press <Y> to save the changes or <N> to return to the setup menu.
If connecting to the RAC Web-based remote access interface from a client system which connects to the Internet through a proxy server, you need to configure the Web browser to connect properly to the Web-based interface. The following sections provide configuration instructions for both browsers supported by the RAC: Microsoft Internet Explorer 5.x or later, and Netscape Navigator 6.x or later.
- From the Internet Explorer main window, click Tools, and then click Internet
Options.
- From the Internet Options window, click the Connections tab.
- Under Local Area Network (LAN) settings, click LAN Settings.
- If the Use a proxy server box is checked, check the Bypass proxy server for local
addresses box.
- Click OK twice.
- From the Netscape Navigator main window, click Edit, and then click Preferences.
- From the Preferences window, click the Advanced category arrow.
- Select the subcategory Proxies.
- If Manual proxy configuration is enabled, append the text localhost to the text in
the No proxy for field.
- Verify that entries in this text box are separated by commas.
The following list describes basic software information for RAC with Red Hat Linux:
- To verify that the RAC driver is loaded, type the following command:
service racser status
- To verify that the RAC event server for the managed system is loaded, type the following command:
service racsrvc status
- To start, stop, get status of, load, or unload the racser service, type the following command:
service racser <action>
where <action> is start, stop, status, load, or unload.
- For additional information on one of the three RAC services, type the following command:
man <service>
where <service> is racser, racvnc, or racsrvc.
|
NOTE: All three services (racser, racsrvc, and racvnc) start automatically when they
are installed and when the system is booted. These services stop automatically when
they are uninstalled or when the system is shut down.
|
- To determine which version of a particular RPM package you have installed, use a package management tool such as GnoRPM, or use the RPM query command (rpm -q). For example:
rpm -q <package_name>
- To determine which files were installed and where they are located, type the following command:
rpm -ql <package_name>
- To remove a package, type the following command:
rpm -e <package_name>
RACs are supported on precompiled kernels that are a part of the Red Hat Linux 7.1 or later distribution. RACs are not supported on recompiled kernels with other configuration options (for example, kernels configured for performance-tuning purposes).
|
NOTICE: Red Hat Linux may fail to load when started on recompiled kernels. If this situation
occurs, you must either restore the kernel and modules from backup, or you must reinstall the
kernel from the Red Hat RPM packages.
