7. Update the DRAC 4 Firmware. See "Updating the DRAC 4 Firmware."
   
   
8. Access the DRAC 4 through a network. See "Accessing the DRAC 4 Through a Network."

Registering the DRAC Host Name With DNS Using DHCP

In DRAC 4 version 1.40 and later, you can configure your DHCP server to dynamically register the DRAC DNS name in your DNS server database. By enabling encryption in both the DHCP and DNS servers, the DRAC DNS name can be registered in a secure environment.

To configure your DRAC to allow the DHCP server to update the DNS database, set the cfgNicUseDhcp object value to 1 (TRUE) and cfgDNSRegisterRac object value to 0 (FALSE). With this configuration, the DRAC will supply cfgDNSRacName to the DHCP server. See "cfgLanNetworking" for information about these object property settings.

NOTE: When you configure the DRAC, the DHCP server must also be configured to perform the DNS database update.

Installing the Software on the Managed System

Installing software on the managed system is optional. Without the managed system software, you lose the ability to use the racadm locally, and for the RAC to capture the last crash screen.

To install the managed system software, install the software on the managed system using the Dell Systems Management Consoles CD. For instructions about how to install this software, see your Quick Installation Guide or Server Administrator User's Guide.

Managed system software will install your choices from the following components on the managed system: the appropriate version of Server Administrator and the appropriate DRAC 4 agent or only the DRAC 4 agent.

NOTE: Do not install the DRAC 4 management station software and the DRAC 4 managed system software on the same system.

Depending on the operating system, the DRAC 4 agent consists of either Microsoft Windows services, Novell NLMs, or Red Hat Enterprise Linux agents. The DRAC 4 agent automatically starts when you boot the managed system. If you install only the DRAC 4 agent, you will not have the ability to view the system's last crash screen or use the Watchdog feature. For more information about the last crash screen, see "Viewing the Last System Crash Screen." For more information about the Watchdog feature, see "System Information."

Configuring the Managed System to Capture the Last Crash Screen

Before the DRAC 4 can capture the last crash screen, configure the managed system with the following prerequisites.

1. Install the managed system software. For more information about installing the managed system software, see the Server Administrator User's Guide.
   
   
2. Run a supported Microsoft Windows operating system with the Windows "automatically reboot" feature deselected in the Windows Startup and Recovery Settings.
   
   
3. Enable the watchdog timer and set the watchdog recovery action to Reset, Power Off, or Power Cycle. To configure the watchdog timer, you must use Server Administrator or IT Assistant. For information about how to configure the watchdog timer, see the Server Administrator User's Guide or the IT Assistant User's Guide. To ensure that the last crash screen can be captured, the watchdog timer must be set to 30 seconds or greater. The default setting is 480 seconds or 8 minutes.
   
   

The last crash screen is not available when the Watchdog recovery action is set to Shutdown or Power Cycle if the managed system is powered off.

Disabling the Windows Automatic Reboot Option

To ensure that the DRAC 4 Web-based interface last crash screen feature works properly, disable the Automatic Reboot option on managed systems running the Microsoft Windows Server 2003 and Windows 2000 Server operating systems.

DRAC 4 Software Basics for Red Hat Enterprise Linux

The DRAC 4 is supported on precompiled kernels that are a part of the Red Hat Enterprise Linux distribution. The DRAC 4 is not supported on recompiled kernels with other configuration options (for example, kernels configured for performance-tuning purposes).

NOTICE: Red Hat Enterprise 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 Package Manager (RPM).

The following list describes basic software information for using a DRAC 4 with the Red Hat Enterprise Linux operating system:

• To verify that the DRAC 4 event server for the managed system is loaded, type the following command:
  
  

service racsvc status

• To start, stop, get status of, restart, or reload the racsrvc service, type the following command:
  
  

service racsvc <action>

where <action> is start, stop, status, or probe.

• For additional information on one of the three DRAC 4 services, type the following command:
  
  

man racsvc

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>
