  Frequently Asked Questions


The DRAC 4 provides a Web-based interface and the racadm CLI (command-line interface) that allows you to configure the DRAC 4 properties and users, perform remote management tasks, and troubleshoot a remote (managed) system for problems. For everyday systems management, you will use the DRAC 4 Web-based interface. This chapter provides information about how to perform common systems management tasks with the DRAC 4 Web-based interface and provides links to the information you may need.

All Web-based interface configuration tasks can also be performed with the racadm CLI. For a list of all racadm CLI and serial/telnet console commands that can be used to perform the text-based equivalents of each task, see "Using the serial and racadm Commands."

NOTE: When you are working in the Web-based interface, see your DRAC 4 online help for context sensitive information about each Web-based interface page.

Accessing the Web-Based Interface

To link to the DRAC 4 remote Web-based interface Log in window, open your Web browser and type https://<IP address>:<port number> (where IP address is the IP address for the DRAC 4 and port number is the HTTPS port number if it has been changed) in the address field and press <Enter>. The DRAC 4 Log in window appears.

Logging In

NOTE: To log in, you must have Log In to DRAC 4 permission.

You can log in as either a DRAC 4 user or as an Active Directory user. To log in, perform the following steps.

Ensuring DRAC 4 Network Security

The DRAC 4 uses certificate management to ensure security for your DRAC 4 network communications.

Certificate Management Overview

A CSR is a digital request to a 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 the security for your DRAC 4, it is strongly recommended that you generate a CSR, submit the CSR to a CA, and upload the certificate returned from the 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.

NOTE: Using the DRAC 4 default certificate for SSL generates a host mismatch warning in Netscape. You must upload a CA-generated SSL certificate to the DRAC 4 for proper security.

Viewing a Server Certificate

Recovering and Troubleshooting the Managed System

This section explains how to perform tasks related to recovering and troubleshooting a crashed remote system using the DRAC 4 Web-based interface. For information about troubleshooting your DRAC 4, see "Troubleshooting."

First Steps to Troubleshoot a Remote System

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

  1. Is the system powered on or off?

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

  3. 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 ("First Steps to Troubleshoot a Remote System") and remote power management (see "Managing Power on a Remote System") to restart the system and watch the reboot process.

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.

NOTE: You must have Execute Server Action Commands permission to perform power management actions.

Selecting Server Control Actions

  1. Select whether to perform an Operating System Shutdown (only for the Reboot System, and Power Off System, Server Control Actions).

If you want to make the system perform an orderly shutdown through the operating system before the selected Server Control Action, select Operating System Shutdown.

NOTE: To use the Operating System Shutdown option, you must first install the DRAC 4 managed system software, otherwise this option will be unavailable. For more information, see your DRAC 4 User's Guide.
  1. Select one of the following Server Control Actions.

    • Reboot System — Resets the system (equivalent to pressing the reset button); the power is not turned off by using this function.

    • Power Cycle System — Turns off the system power and turns it on again (equivalent to pressing the power button twice).

    • Power Off System — Turns off the system power (equivalent to pressing the power button).

    • Power On System — Turns on the system power (equivalent to pressing the power button).

  2. Click Apply to perform the power management action (for example, cause the system to power cycle).

Other Options

The Server Control page provides buttons (see Table 4-22) in the top-right corner of the screen.

Using the SEL

The System Event Log (SEL) page displays system-critical events that occur on the managed system. The SEL is generated by the Baseboard Management Controller (BMC) on the managed system and by the DRAC 4 if you have configured it to monitor any managed system events. This page displays the date, time, and a description of each event generated by the BMC and other instrumentation on the managed system. You can configure the DRAC 4 to send email or SNMP alerts when specified events occur.

The SEL displays the event severity information in Table 4-23.

The DRAC 4 Log provides the following information.

Table 4-23. Status Indicator Icons

A green check mark indicates a healthy (normal) status condition.

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.

Table 4-25. Status Indicator Icons

A green check mark indicates a healthy (normal) status condition.

A yellow triangle containing an exclamation point indicates a warning (noncritical) status condition.

A red X indicates a critical (failure) status condition.

A blank space indicates that the status is unknown.

  • Date and Time — The date and time (for example, Sat Dec 19 16:55:47 2004). When the DRAC 4 is unable to communicate with the managed system, the letters DSU (DRAC 4 start up) appear before the time, followed by the time elapsed since the DRAC 4 was started.

  • User — The name of the user logging into the DRAC 4.

  • ID — The event identification number of the message displayed.

  • Description — A brief description of the event.

ifconfig

Displays the contents of the network interface table.

netstat

Prints the content of the routing table. If the optional interface number is provided in the text field to the right of the netstat option, then netstat prints additional information regarding the traffic across the interface, buffer usage, and other network interface information.

ping <IP Address>

Verifies that the destination IP address is reachable from the DRAC 4 with the current routing-table contents. A destination IP address must be entered in the field to the right of this option. An ICMP (Internet control message protocol) echo packet is sent to the destination IP address based on the current routing-table contents.

getcoredump

Displays the last controller crash, including detailed information such as register values and a memory map recorded when the most recent controller crash occurred; displays the message "No CORE dump available" if no previous controller crash has occurred or if the data has been deleted.

settracelog

Enables you to set debug trace levels to identify the types of messages being sent on the local network. The -d option traces the DHCP packets sent and received. The -i option traces IP packets sent and received. For example, type settracelog
-i to trace IP packets sent and received.

gettracelog

Displays a UNIX®-style system log. This log is a volatile, memory-resident log that contains time-stamped entries.

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 operating-system specific error codes (relating to the internal DRAC 4 operating system, 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).

Frequently Asked Questions

Table 4-32 lists frequently asked questions and answers.

Table 4-32. Managing and Recovering a Remote System: Frequently Asked Questions

Question

Answer

The following message is displayed for unknown reasons:

Remote Access: SNMP Authentication Failure

Why does this happen?

As part of discovery, IT Assistant attempts to verify the get and set community names of the device. In IT Assistant, you have the get community name = public and the set community name = private. By default, the community name for the DRAC 4 agent is public. When IT Assistant sends out a set request, the DRAC 4 agent generates the SNMP authentication error because it will only accept requests from community = public.

You can change the DRAC 4 community name using the racadm command line utility.

To see the DRAC 4 community name, use the following command:

racadm getconfig -g cfgOobSnmp

To set the DRAC 4 community name, use the following command:

Racadm config -g cfgOobSnmp -o cfgOobSnmpAgentCommunity <community name>

To prevent SNMP authentication traps from being generated, you must input community names that will be accepted by the agent. Since the DRAC 4 only allows one community name, you must input the same get and set community name for IT Assistant discovery setup.

Why are the remote racadm and Web-based services unavailable after a property change?

It may take several minutes for the remote racadm services and the Web-based interface to become available again after a reset of the DRAC 4 Web server

The DRAC 4 Web server is reset after the following occurrences:

  • When the cfgRacTuneHttpsPort property is changed (including when a config -f <config file> changes it)
  • When racresetcfg is used
  • When the DRAC 4 is reset

When accessing the DRAC 4 Web-based interface, I get a security warning stating the hostname of the SSL certificate does not match the hostname of the DRAC 4.

DRAC 4 includes a default DRAC 4 server certificate to ensure network security for the Web-based interface and remote racadm features. When this certificate is used, the web browser displays a security warning because the default certificate is issued to RAC default certificate which does not match the host name of the DRAC 4 (for example, the IP address). To address this security concern, upload a DRAC 4 server certificate issued to the IP address of the DRAC 4. When generating the certificate signing request (CSR) to be used for issuing the certificate, ensure that the common name (CN) of the CSR matches the IP address of the DRAC 4 (for example, 192.168.0.120). See "Ensuring DRAC 4 Network Security" for more information about generating CSRs and issuing certificates.

When accessing the DRAC 4 Web-based interface, I get a security warning stating the SSL certificate was issued by a certificate authority (CA) that is not trusted.

DRAC 4 includes a default DRAC 4 server certificate to ensure network security for the Web-based interface and remote racadm features. This certificate was not issued by a trusted CA. To address this security concern, upload a DRAC 4 server certificate issued by a trusted CA (for example, Thawte or Verisign). See "Ensuring DRAC 4 Network Security" for more information about issuing certificates.

Why doesn't my DNS server register my DRAC 4?

Some DNS servers only register names of 31 characters or fewer.
