Configuring EMC Celerra SNMP Traps

The following sections provide the configuration steps to be performed on the EMC Celerra control station to send SNMP traps to the Enterprise Manager EMC Celerra Plug-in. For more information about the EMC Celerra event and notification system, refer to the following EMC-provided documentation:

Celerra Network Server Technical Module — Configuring Celerra Events and Notifications

Configuring the SNMP Trap Configuration File

The SNMP Trap Configuration file specifies the SNMP Manager to which the trap should be sent. To receive SNMP traps from the Celerra Control Station, you can modify the default trap configuration file /nas/site/trap.cfg or create a new configuration file. A different file is required if more than one SNMP manager is listening for different SNMP traps. The SNMP Trap Configuration file is referenced in the Notification Configuration file, which is described in the next section.

If you plan to use the default Notification Configuration file specific to Enterprise manager as described in the next section, you should create a new SNMP Trap Configuration file (em_trap.cfg) by performing the following steps.

  1. Ensure that the prerequisites for SNMP are met. See "Prerequisites".

  2. Log in to the EMC Celerra control station as a NASADMIN user.

  3. Enter:

    cd /nas/site

  4. Enter:

    cp trap.cfg em_trap.cfg

  5. Modify the contents of em_trap.cfg by uncommenting and changing snmpmanager to point to the emagenthost:emagentport format, as shown in the following example:

    snmpmanager 140.87.1.84:5125 ; communityname public

Creating and Loading a Notification Configuration File

The Notification Configuration file specifies the list of events for which notifications are to be sent. The default notification file,/nas/sys/nas_eventlog.cfg, contains all the default notification events with different types of notification methods (call home, SNMP trap, email, log, exec, and so forth).

You can either modify the default notification file,/nas/sys/nas_ eventlog.cfg, or create a new one specific to Enterprise Manager with a subset of events. The following procedure provides a sample Notification Configuration File, em_snmp_eventlog.cfg, which contains power status, fan status, reboot events, and failover events. You can add more events as required. Refer to the EMC-provided documentation, Celerra Network Server Technical Module — Configuring Celerra Events and Notifications, for details on the format of the Notification Configuration file.

Perform the following steps to create and load the file:

  1. Log in to the EMC Celerra control station as a NASADMIN user.

  2. Create the em_snmp_eventlog.cfg file with the following contents:

    #
    # Notification file for Enterprise Manager plug-in for EMC Celerra
    #
    # BoxMonitor
    # Fan status, power status events for CNS-14, Reboot events for  ALL platforms
    facilitypolicy  131, 4
        disposition range=1-1, trap "/nas/site/em_trap.cfg 2"
        disposition range=3-15, trap "/nas/site/em_trap.cfg 2"
        disposition range=18-21, trap "/nas/site/em_trap.cfg 2"
        disposition range=38-39, trap "/nas/site/em_trap.cfg 2"
        disposition range=43-43, trap "/nas/site/em_trap.cfg 2"
        disposition range=57-58, trap "/nas/site/em_trap.cfg 2"
        disposition range=62-67, trap "/nas/site/em_trap.cfg 2"
        disposition range=70-70, trap "/nas/site/em_trap.cfg 2"
        disposition range=73-73, trap "/nas/site/em_trap.cfg 2"
        disposition range=100-115, trap "/nas/site/em_trap.cfg 2"
        disposition range=200-215, trap "/nas/site/em_trap.cfg 2"
        disposition range=300-315, trap "/nas/site/em_trap.cfg 2"
     
    #
    # Enclosure Monitor
    # Fan status, power status events for NS platform
    facilitypolicy 86, 7
        disposition severity=0-3, trap "/nas/site/em_trap.cfg 2"
        disposition severity=4-4, trap "/nas/site/em_trap.cfg 3"
    
  3. Edit the file to add any other events if needed.

  4. Enter the nas_event command as shown in the following example:

    [nasadmin@erpcel01-con site]$ nas_event -Load /nas/site/em_event_config.cfg EventLog : will load /nas/site/em_snmp_eventlog.cfg... done

  5. Verify if the file is loaded by entering the nas_event command as shown in the following example:

    [nasadmin@erpcel01-con site]$ nas_event -Load -info

    Loaded config. files:

    1: /nas/sys/nas_eventlog.cfg

    2: /nas/http/webui/etc/web_client_eventlog.cfg

    3: /nas/jserver/event_config/events.cfg

    4: /nas/site/em_snmp_eventlog.cfg

To map EMC severities (0-7) to Enterprise Manager severities, use the following required Oracle SNMP Enterprise-specific traps:

  • SNMP trap 2 to send critical alerts (EMC-defined severity <= 3)

  • SNMP trap 3 to send warning alerts (EMC-defined severity <= 4)

Sending an SNMP Trap Test

After you deploy the plug-in and set up a target as instructed in the System Monitoring Plug-in Installation Guide for EMC Celerra Server, you can use the nas_snmptrap command to send SNMP trap tests.

  1. Log in to the EMC Celerra control station as a NASADMIN user.

  2. Run the nas_snmptrap command.

    • The syntax of the command is as follows:

      /nas/sbin/nas_snmptrap <config_file_path> -m /nas/sys/emccelerra.mib -r <trap_number> -f <facility_id> -i <event_id> -s <severity_level> -d "<description>"

      <config_file_path> = the path of the trap configuration file /nas/sys/emccelerra.mib = the Celerra MIB file <trap_number> = the unique trap number for the event <facility_id> = the ID number of the facility generating the event <event_id> = the event ID number <event_id> = the event ID number <description> = the description of the trap

    • The following example shows how to send a critical alert:

      /nas/sbin/nas_snmptrap /nas/site/em_trap.cfg -m /nas/sys/emccelerra.mib -r 2 -f 64 -i 2 -s 2 -d "Test SNMP trap Critical Alert"

    • The following example shows how to send a warning alert:

      /nas/sbin/nas_snmptrap /nas/site/em_trap.cfg -m /nas/sys/emccelerra.mib -r 3 -f 65 -i 3 -s 3 -d "Test SNMP trap Warning Alert"

  3. Verify the alerts as follows:

    1. Log in to Grid Control.

    2. Go to the EMC Celerra Target. Under the Reports Tab, view the EMC Celerra SNMP Trap-based Alerts Report. This should list the alert corresponding to the trap test that is sent.

    3. Go to the Grid Control Console Home Page. Under All Targets Alerts, Click the Critical or Warning link. Filter the targets by EMC Celerra Server type. You should see the alert corresponding to the trap test that is sent. You can then select and clear the alert.

Undeploying the Plug-in

Follow these steps to undeploy the plug-in from an Agent:

  1. Log in to Enterprise Manager Grid Control as a Super Administrator.

  2. Select the Targets tab, then the All Targets subtab. The All Targets page appears.

  3. Select the EMC Celerra Server Plug-in target and click Remove. You must do this step for all targets of the plug-in.

  4. Make sure that the preferred credentials are set on the Agents where the plug-in was deployed.

  5. Click the Setup link in the upper right corner of the All Targets page, then click the Management Plug-ins link on the left side of the Setup page. The Management Plug-ins page appears.

  6. Click the icon in the Undeploy column for the EMC Celerra Server Plug-in. The Undeploy Management Plug-in page appears.

  7. Check all the Agents that are currently deployed with the EMC Celerra Server Plug-in and click OK.

    You must undeploy the plug-in from every Agent in the system to completely remove it from the enterprise.

  8. Select the EMC Celerra Server Plug-in on the Management Plug-ins page and click Delete.
