Installing the Software on the Managed System

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

To install the managed system software, install the software on the managed system using the Systems Management 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. 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 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, you must 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, you must disable the Automatic Reboot option on managed systems running the Windows Server 2003 and Microsoft Windows 2000 Server operating systems.

Installing the Sun Java Plug-In to Use Mozilla

NOTE: For a list of the latest supported Java Virtual Machine (JVM) plug-ins, see the racread.txt file on your Systems Management CD or at the Dell Support website at support.dell.com.

You must install Java plug-in 1.4.2 or later to use the Mozilla Web browser. Perform the following steps to install JRE:

1. Launch the installation script by using the following commands from the directory in which the script is located:
   
   

chmod a+x j2re-1_4_<version number>-linux-i586-rpm.bin

./j2re-1_4_<version number>-linux-i586-rpm.bin

The script displays a binary license agreement, which you are prompted to accept before continuing the installation. After you have accepted the license agreement, the installation script creates the file j2re-1_4_<version number>-linux-i586.rpm in the current directory.

2. To become the root user, type the su command and type the power-user password.
   
   
3. Run the following rpm command to install the packages. This command installs the packages comprising the Java 2 Runtime Environment (J2RE):
   
   

rpm -iv j2re-1_4<version number>-linux-i586.rpm

Only one Java plug-in can be registered at a time. If you have never registered a Java plug-in, go to the next step; otherwise, go to step 5.

Most Mozilla installations use symbolic links to where the Java plug-in is located. The name of the symbolic link is libjavaplugin_oji.so, which is in the /plugins subdirectory of Mozilla.

For example:

cd /usr/lib/mozilla<version number>/plugins

rm libjavaplugin_oji.so

4. Register the Java plug-in.
   
   

Locate the libjavaplugin_oji.so file in the j2re1.4<version number> directory. Usually it is located in the /i386/ns600 or /i386/ns610 subdirectory. Use the create a symbolic link feature in Mozilla that points to the libjavaplugin_oji.so file in the /i386/ns610 subdirectory.

For example:

cd <Mozilla>/plugins

ln s j2re1.4<version number>/plugin/i386/ns610/libjavaplugin_oji.so libjavaplugin_oji.so

NOTE: Create the link using the /plugins subdirectory of Mozilla. You cannot create the link from <JRE> directory.

5. Start Mozilla and go to Tools® Web Development® Java Console.
   
   

The version of JRE is displayed at the top of the Java Console window. If the version that is shown is not the same as the one you downloaded, then registration did not work. The same is true if the Java Console menu option is grayed out.

Installing the Sun Java Plug-In to Use Netscape Navigator 7.02 or 7.1

To access the DRAC 4 Web-based interface using Netscape Navigator 7.02 or 7.1 on systems running either the Windows or Red Hat Enterprise Linux operating systems, you must install Java plug-in 1.4.2 or later.

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 RPM packages.

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>
