DRAC 4 Overview

The Dell™ Remote Access Controller 4 (DRAC 4) is a systems management hardware and software solution designed to provide remote management capabilities, crashed system recovery, and power control functions for Dell PowerEdge™ systems.

By communicating with the system’s baseboard management controller (BMC), the DRAC 4 can be configured to send you email alerts for warnings or errors related to voltages, temperatures, and fan speeds. The DRAC 4 also logs event data and the most recent crash screen (for systems running the Microsoft probable cause of a system crash.

Depending on your system, the DRAC 4 hardware is either a daughter card (DRAC 4/I) or a half-length PCI card (DRAC 4/P). The DRAC 4/I and DRAC 4/P are identical except for the hardware differences (see "DRAC 4 Hardware Featu re s" ).

Installing and Setting Up the DRAC 4 27

Software Installation and Configuration Overview

This section provides a high-level overview of the DRAC 4 software installation and configuration process. Configure your DRAC 4 using the Web-based interface, racadm CLI, or Serial/Telnet console. Network configuration can also be performed using operating system utilities (Option ROM).

For more information about the DRAC 4 software components, see "Installing the Software on the Managed System."

NOTE: For basic information about using the Red Hat Enterprise Linux operating

system, see "DRAC 4 Software Basics for Red Hat Enterprise Linux."

Installing Your DRAC 4 Software

To install your DRAC 4 software, perform the following steps in order:

Update the system BIOS.

Install the software on the managed system. See "Installing the Software on the Managed System."

Install the software on the management station. See "Installing the Software on the Management Station."

Configuring Your DRAC 4 Software

To configure your DRAC 4 software, perform the following steps in order:

Select one of the following configuration tools:

NOTICE: Using more than one configuration tool at the same time may

generate unexpected results.

• Web-based interface

•racadm CLI

• Serial/Telnet console

• Operating system utilities (Option ROM)

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 Console and Agent CD. For instructions about how to install this software, see your Quick Installation Guide or Server Administrator User's Guide.

Installing and Setting Up the DRAC 4 29

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).

Installing and Setting Up the DRAC 4 45

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>

Configuring the DRAC 4 to Use a Serial or Telnet Text Console

The DRAC 4 provides serial and telnet command interfaces designed to perform all of the configuration and systems management functions using the DRAC 4 Web-based interface or racadm CLI.

This section provides information about the serial/telnet text console features, and explains how to set up your system so you can perform systems management actions through a serial/telnet console.

Serial and Telnet Console Features

The DRAC 4 supports the following serial and telnet console redirection features:

• One serial client connection and up to four telnet client connections at one time

• Access to the managed system consoles through the system serial port and through the DRAC 4 NIC

• Serial/telnet console commands that allow you to power-on, power-off, power-cycle, reset, view logs, view sensor status, or configure the DRAC 4

• Serial/telnet console support for the scripting

• Command-line editing and history

•The

NOTE: If you are running Red Hat Enterprise Linux on the managed system,

the connect com2 serial command provides a true Red Hat Enterprise Linux console stream interface.

Configuring the DRAC 4 to Use a Serial or Telnet Text Console 49

• Menu-based VT-100 block screen interface that provides easy operation of commonly used commands including reset, power-on, and power-off

NOTE: Because the racadm command does not have access to a file system

on a serial or telnet console, several options (such as reading or writing a file) are not supported by the racadm command through a serial or telnet console. For more information about supported racadm commands for the serial and telnet consoles, see "Using the Serial and racadm Commands."

• Optional idle timeout setting on SSH connections for enhanced security, which is controlled by the "cfgSsnMgtSshTelnetIdleTimeout (Read/Write)" object

Enabling and Configuring the Managed System to Use a Serial or Telnet Console

This section provides information about enabling and configuring a serial/telnet console on the managed system.

NOTE: The connect com2 serial command requires that the Serial Port setting

under the BIOS setup group Integrated Devices be set to RAC. When a telnet session is established to the DRAC 4 and the setting of this serial port is not RAC, connect com2 yields a blank screen.

NOTE: The connect com2 serial command is not supported on systems running the

Novell NetWare operating system.

Configuring the System Setup Program on the Managed System

Perform the following steps to configure your System Setup program to redirect output to a serial port.

NOTE: You must configure the System Setup Program in conjunction with the

connect serial/telnet command.

58 Configuring the DRAC 4 to Use a Serial or Telnet Text Console

Using the Secure Shell (SSH)

Secure Shell (SSH) is a command line session that includes the same capabilities as a telnet session, but with higher security. The DRAC 4 supports SSH version 2 with password authentication. SSH is enabled on the DRAC 4 when you install or update your DRAC 4 firmware.

NOTE: SSH is not available for the first fifteen minutes of operation after

installing/updating the DRAC 4 firmware. During this time the host keys are generated internally. No intervention is required for host key generation. If this operation is interrupted for any reason, key generation will start again when the DRAC 4 is restarted.

You can use either PuTTY or OpenSSH on the management station to connect to the managed system’s DRAC 4.

NOTE: Run OpenSSH from a VT100 or ANSI terminal emulator on Windows. Running

OpenSSH at the Windows command prompt does not result in full functionality (for example, some keys do not respond and no graphics are displayed).

Only one SSH session is supported at any given time. The session timeout is controlled with the cfgSsnMgtSshTelnetIdelTimeout object as described in the "DRAC 4 Property Database Group and Object Definitions."

Enabling SSH

You can enable the SSH on the DRAC 4 with the following command:

racadm config -g cfgSerial -o cfgSerialSshEnable 1

Changing the SSH Port

You can change the SSH port with the following command:

racadm config -g cfgRacTuning -o cfgRacTuneSshPort 0x<port number>

For more information on cfgSerialSshEnable and cfgRacTuneSshPort objects, see "DRAC 4 Property Database Group and

Object Definitions."

Configuring the DRAC 4 to Use a Serial or Telnet Text Console 59

Supporting Cryptography Schemes

The DRAC 4 SSH implementation supports multiple cryptography schemes:

• Asymmetric Cryptography:

– Diffie-Hellman DSA/DSS 512-1024 (random) bits per NIST

specification

• Symmetric Cryptography:

– AES256-CBC

– RIJNDAEL256-CBC

– AES192-CBC

– RIJNDAEL192-CBC

– AES128-CBC

– RIJNDAEL128-CBC

– BLOWFISH-128-CBC

– 3DES-192-CBC

– ARCFOUR-128

•Message Integrity:

– HMAC-SHA1-160

–HMAC-SHA1-96

– HMAC-MD5-128

– HMAC-MD5-96

• Authentication:

–Password

– SSHv2 (SSHv1 is not supported)

60 Configuring the DRAC 4 to Use a Serial or Telnet Text Console

Connecting to the Managed System Through the Local Serial Port or Telnet Management Station (Client System)

The managed system provides access between the DRAC 4 and the serial port on your system to enable you to power on, power off, or reset the managed system and access logs.

The serial console is available on the DRAC 4 through the managed system external serial connector. Only one serial client system (management station) can be active at any given time.

The telnet and SSH consoles are available on the DRAC 4 through the DRAC 4 NIC. Up to four telnet client systems and one SSH client can connect at any given time.

The management station connection to the managed system serial or telnet console requires the use of management station terminal emulation software (see "Configuring the Management Station Terminal Emulation Software" for more information).

The following subsections explain how to connect your management station to the managed system through a managed system external serial port using terminal software and a null modem cable, or by telnet using terminal software through the managed system DRAC 4 NIC.

Connecting the DB-9 Cable

To connect to the managed system using a serial text console, connect a DB-9 null modem cable to the COM port that you are using on the managed system. Not all DB-9 cables carry the pinout/signals necessary for this connection. The DB-9 cable for this connection must conform to the specification shown in Table 3-4.

NOTE: You can also use this cable for BIOS text console redirection with the

DRAC 4 serial console disabled.

Using a Serial or Telnet Console

NOTE: If you are running Windows XP or Windows 2003 and experience problems

with characters in a DRAC 4 telnet session, navigate to the Microsoft Support website located at support.microsoft.com website and search for Knowledge Base article 824810, which provides a hot fix for this issue. This problem may manifest itself as an apparently frozen login (the return key does not respond and the password prompt does not appear).

NOTE: On a management station running Windows 2000, pressing the <F2> key

does not enter the BIOS setup. To resolve this issue, use the telnet client that is included with the Windows Services for UNIX from Microsoft). Browse to www.microsoft.com/downloads/ and search for

"Windows Services for UNIX 3.5."

NOTE: When a telnet login attempt is invalid, a single session is counted toward

the maximum of four sessions for approximately one minute after the invalid login attempt. If three valid sessions exist, this invalid session will prevent further login attempts for that minute.

Serial and telnet commands, and racadm CLI can be typed in a serial or telnet console. These commands can be executed on the server locally or remotely. The local racadm CLI is installed for use as a root user only. For more information about the serial/telnet commands and racadm CLI, see "Using the Serial and racadm Commands."

Securing DRAC 4 Communications Using SSL and Digital Certificates

The DRAC includes a Web server that is configured to use the industrystandard SSL security protocol to transfer encrypted date over the Internet. Built upon public-key and private-key encryption technology, SSL is a widely accepted technique for providing authenticated and encrypted communication between clients and servers to prevent eavesdropping across a network.

SSL allows an SSL-enabled system to perform the following tasks:

• Authenticate itself to an SSL-enabled client

• Allow the client to authenticate itself to the server

• Allow both systems to establish an encrypted connection

This encryption process provides a high level of data protection. The DRAC employs the 128-bit SSL encryption standard, the most secure form of encryption generally available for Internet browsers in North America.

The DRAC Web server includes a Dell self-signed SSL digital certificate (Server ID). To ensure high security over the Internet, replace the Web server SSL certificate by submitting a request to the DRAC to generate a new Certificate Signing Request (CSR).

Managing and Recovering a Remote System 81

Certificate Signing Request (CSR)

A CSR is a digital request to a Certificate Authority (CA) for a secure server certificate. Secure server certificates ensure the identity of a remote system and ensure that information exchanged with the remote system cannot be viewed or changed by others. To ensure this security for your DRAC 4, it is strongly recommended that you generate a CSR and submit the CSR to a CA.

A Certificate Authority is a business entity that is recognized in the IT industry for meeting high standards of reliable screening, identification, and other important security criteria. Examples of CAs include Thawte and VeriSign. After the CA receives your CSR, they review and verify the information the CSR contains. If the applicant meets the CA’s security standards, the CA issues a certificate to the applicant that uniquely identifies that applicant for transactions over networks and on the Internet.

After the CA approves the CSR and sends you a certificate, you must upload the certificate to the DRAC 4 firmware. The CSR information stored on the DRAC 4 firmware must match the information contained in the certificate.

Viewing a Server Certificate

Use the Server Certificate Information page to view a server certificate for your DRAC 4. Table 4-11 provides information about the server certificate.

• Managing Power on a Remote System

•Using the SEL

•Using the DRAC 4 Log

• Viewing the Last System Crash Screen

• Using the Diagnostic Console

First Steps to Troubleshoot a Remote System

The following questions are commonly used to troubleshoot high-level problems in the managed system:

Is the system powered on or off?

If powered on, is the operating system functioning, crashed, or just frozen?

If powered off, did the power turn off unexpectedly?

For crashed systems, you can check the last crash screen (see "Viewing the Last System Crash Screen"), and use console redirection (see "Using Console Redirection") and remote power management (see "Managing Power on a Remote System") to restart the system and monitor the reboot process.

Managing and Recovering a Remote System 89

Managing Power on a Remote System

The DRAC 4 allows you to remotely perform several power management actions on the managed system to try and recover after a system crash or other problem. Use the Server Control page to perform an orderly shutdown through the operating system when rebooting, and power the system on or off.

Using the DRAC 4 Log

The DRAC 4 Log is a persistent log maintained in the DRAC 4 firmware. The log contains a list of user actions (such as log in and log out) and alerts issued by the DRAC 4. The oldest entries are overwritten when the log becomes full. If the DRAC 4 loses communication with the managed system, all entries that the DRAC 4 would have added to the System Event Log (SEL), such as a power failure, are added to the DRAC 4 Log until communication is re-established.

The DRAC 4 Log provides the information in Table 4-25.

Troubleshooting Network Problems

The internal DRAC 4 Trace Log can be used by administrators to debug alerting, or networking from the DRAC 4. The Trace Log can be accessed from the DRAC 4 Web-based interface by clicking the Diagnostics tab, and typing the gettracelog command. The Trace Log will appear and tracks the following information:

• DHCP — Traces packets sent to and received from a DHCP server.

• IP — Traces IP packets sent and received.

NOTE: In the DRAC 4 Trace Log, nonprintable ASCII characters are translated to

printable ASCII characters. If the character code is less than 0x20, or between 0x7f and 0xa0 (inclusive), the value 0x40 is exclusive and the character before printing, after a "^" is added to the beginning. As a result, the ASCII carriage return character, 0xd, is printed as "^M" in the Trace Log.

NOTE: The DRAC 4 will not echo an ICMP (ping) with a packet size larger than

1500 bytes.

The trace log may also contain DRAC 4 firmware-specific error codes (relating to the internal DRAC 4 firmware, not the managed system’s operating system). Use Table 4-30 to help diagnose network problems reported by the internal DRAC 4 operating system.

Troubleshooting Alerting Problems

You can use logged SNMP trap information to troubleshoot a particular type of DRAC 4 alert. SNMP trap deliveries are logged in the Trace Log by default. However, since SNMP does not confirm delivery of traps, it is best to trace the packets on the managed system using a network analyzer or a tool such as Microsoft’s snmputil.

DRAC 4 Log Messages

DRAC 4 Log messages can be used by administrators to debug alerting from the DRAC 4. Table 4-31 provides a list of the DRAC 4 log message ID numbers, messages, and suggested actions to take.

NOTE: In Table 4-31, the character "L" is sometimes displayed in the Message ID

column. "L" represents the severity level or type of the message, which can be one of the following: W (warning), E (error), S (severe), F (fatal), or A (always).
