3 Post-Discovery Configuration and Verification

Once the Oracle Exalytics Machine has been discovered through Enterprise Manager Cloud Control 13c, you must complete the following post-discovery configuration:

3.1 Configure the Compute Node ILOM SNMP for Enterprise Manager Monitoring

The compute node ILOM targets are responsible for displaying a number of disk failure alerts for their respective compute node that are received as SNMP traps. To configure the ILOM SNMP:

  1. Log in to the ILOM console.
  2. In the left-hand navigation, select ILOM Administration, then select Notifications. Select a rule that has a disable level and click Edit as shown in Figure 3-1:

    Figure 3-1 Creating a New ILOM Alert Rule


    new ilom

  3. In the Edit pop-up window, enter the following information:
    • Level: select Minor from the drop-down menu.

    • Type. select SNMP Trap from the drop-down menu.

    • Address: enter the IP address of the host where agent monitoring the ILOM is running.

    • Destination port: enter the agent port number.

    • SNMP Version: select v2c from the drop-down menu.

    • Community: enter public.

    Click Save to save the changes, as shown in Figure 3-2:

3.2 Verify the Compute Node ILOM SNMP

To verify the ILOM SNMP configuration:

  1. Log in to the compute node host as root and run the following command:
    # ipmitool -I lan -H myhost.mycompany.com -U root -P welcome1 -L OPERATOR event PCIE5/PRSNT absent assert
    

    The results of this command should look like this:

    PCIE5/PRSNT absent assert
    Finding sensor PCIE5/PRSNT... ok
       0 | Pre-Init Time-stamp | Entity Presence #0xa7 | Absent | Asserted
    
  2. Refresh the ILOM target page. An incident should appear in the Incidents section. Once it is verified, clear the incident in Cloud Control.

3.3 Setting Up Enhanced Power Distribution Unit (PDU) Monitoring

This section provides instructions for setting up SNMP for PDU targets.

To complete the setup for Enhanced PDU Monitoring, follow these steps:
  1. Browse the URL for Enhanced PDU. For example, https://<PDU IP Address>.
  2. Use your login credentials to gain access.
  3. Select the Net Configuration tab.
    1. Check Enable SNMP v1/v2. .
    2. Set SNMP Port to: 161.
    3. Select Original-MIB radio button.
    4. In the NMS (SNMP v1/v2) section, set agent IP address and community name (under Read-Only Community).

  4. Select the Parameter tab.
    1. In theinput section: select trap enable and set the appropriate threshold value for each input. Refer to Oracle® Exadata Database Machine Installation and Configuration Guide 13c Release 3 (13.3) to learn more about PDU threshold.

  5. From the PDU’s Monitoring Setting page, change the value to Module 3.

    Note:

    This step is only for 13c target type.
