Monitoring and Alert Management251 Testing e-mail Alerting The RAC e-mail alerting feature allows users to receive e-mail alerts when a critical event occurs on the managed system. The following example shows how to test the e-mail alerting feature to ensure that the RAC can properly send out e-mail alerts across the network. racadm testemail -i 2 NOTE: Ensure that the SMTP and Email Alert settings are configured before testing the e-mail alerting feature. See Configuring E-Mail Alerts for more information. Testing the RAC SNMP Trap Alert Feature The RAC SNMP trap alerting feature allows SNMP trap listener configurations to receive traps for system events that occur on the managed system. The following example shows how a user can test the SNMP trap alert feature of the RAC. racadm testtrap -i 2 Before you test the RAC SNMP trap alerting feature, ensure that the SNMP and trap settings are configured correctly. See testtrap and testemail subcommand descriptions to configure these settings. Frequently Asked Questions Why is the following message displayed: Remote Access: SNMP Authentication Failure As part of discovery, IT Assistant attempts to verify the device’s get and set community names. In IT Assistant, you have the get community name = public and the set community name = private. By default, the community name for the DRAC 5 agent is public. When IT Assistant sends out a set request, the DRAC 5 agent generates the SNMP authentication error because it will only accept requests from community = public. You can change the DRAC 5 community name using RACADM. To see the DRAC 5 community name, use the following command: racadm getconfig -g cfgOobSnmp
252Monitoring and Alert Management To set the DRAC 5 community name, use the following command: racadm config -g cfgOobSnmp -o cfgOobSnmpAgentCommunity < community name> To prevent SNMP authentication traps from being generated, you must enter community names that will be accepted by the agent. Since the DRAC 5 only allows one community name, you must use the same get and set community name for IT Assistant discovery setup.

Using the IPMI Remote Access Serial Interface In the IPMI serial interface, the following modes are available: IPMI terminal mode — Supports ASCII commands that are submitted from a serial terminal. The command set has a limited number of commands (including power control) and supports raw IPMI commands that are entered as hexadecimal ASCII characters. IPMI basic mode — Supports a binary interface for program access, such as the IPMI shell (IPMISH) that is included with the Baseboard Management Utility (BMU). To configure the IPMI mode using RACADM: 1 Disable the RAC serial interface. At the command prompt, type: racadm config -g cfgSerial -o cfgSerialConsoleEnable 0 2 Enable the appropriate IPMI mode.
