This section explains how to perform tasks related to recovering and troubleshooting a crashed DRAC 5.
You can use one of the following tools to troubleshoot your DRAC 5:
The RAC Log is a persistent log maintained in the DRAC 5 firmware. The log contains a list of user actions (such as log in, log out, and security policy changes) and alerts issued by the DRAC 5. The oldest entries are overwritten when the log becomes full.
To access the RAC Log from the DRAC 5 user interface (UI):
The RAC Log provides the information listed in Table 16-1.
Table 16-1. RAC Log Page Information
The RAC Log page provides the buttons listed in Table 16-2.
Table 16-2. RAC Log Buttons
NOTE: If you are using Internet Explorer and encounter a problem when saving, be sure to download the Cumulative Security Update for Internet Explorer, located on the Microsoft Support website at support.microsoft.com.
Use the getraclog command to view the RAC log entries.
racadm getraclog -i
The getraclog -i command displays the number of entries in the DRAC 5 log.
racadm getraclog [options]
|NOTE: For more information, see "getraclog."|
You can use the clrraclog command to clear all entries from the RAC log.
The DRAC 5 provides a standard set of network diagnostic tools (see Table 16-3) that are similar to the tools included with Microsoft® Windows® or Linux-based systems. Using the DRAC 5 Web-based interface, you can access the network debugging tools.
To access the Diagnostic Console page:
Table 16-3 describes the options that are available on the Diagnostic Console page. Type a command and click Submit. The debugging results appear in the Diagnostic Console page.

The internal DRAC 5 Trace Log is used by administrators to debug DRAC 5 alerting and networking issues.
To access the Trace Log from the DRAC 5 Web-based interface:
|NOTE: You can use this command from the command line interface also. See "gettracelog" for more information.|
The Trace Log tracks the following information:
The trace log may also contain DRAC 5 firmware-specific error codes that are related to the internal DRAC 5 firmware, not the managed system's operating system.
|NOTE: The DRAC 5 will not echo an ICMP (ping) with a packet size larger than 1500 bytes.|
The racadm racdump command provides a single command to get dump, status, and general DRAC 5 board information.
|NOTE: This command is available only on Telnet and SSH interfaces. For more inform, see the "racdump" command.|
The racadm coredump command displays detailed information related to any recent critical issues that have occurred with the RAC. The coredump information can be used to diagnose these critical issues.
If available, the coredump information is persistent across RAC power cycles and will remain available until either of the following conditions occur:
The racadm coredumpdelete command can be used to clear any currently resident coredump data stored in the RAC.
See the "coredump" and "coredumpdelete" for more information.
