MAP1305 Isolating SNMP notification problems

This MAP provides guidance on how to isolate SNMP Notification problems.

About this task

The HMC can send SNMP Trap messages to the customer’s LAN when it requires service or to notify the customer of certain information events. The HMC generates Simple Network Management Protocol (SNMP) traps and supports a read-only management information base (MIB) to allow monitoring by the customer’s network.
Notes:
  1. SNMP is required for PPRC status reporting for Copy Services in Open Systems environments. For SNMP to function, the HMC must be attached to the customer LAN. The configured SNMP traps are sent to the TCP/IP addresses of the Trap Destinations that are configured by the IBM® service representative through the Service Agent/Customer Notification panels.
  2. These addresses must be the dotted TCP/IP address form.

Procedure

  1. Verify that the SNMP notification is configured per the Customization worksheets. The SNMP is configured as follows:
    1. From the navigation area, click Service Management.
    2. In the right work area, go to the Connectivity section and click Manage Serviceable Event Notification.
    3. On the Customer Notification panel, click SNMP Trap Configuration.
    4. Ensure that the customer-supplied trap destinations are listed. Click on each of the destinations, select Change and verify that the required events are selected for notification.
      Note: To test SNMP notification, make sure that Problem Log Entry Created is selected.
    5. Click OK.
  2. Test SNMP notification by creating a Test PMH. (The side effect of this is that it will create a Problem Log Entry and a corresponding SNMP event). Perform the following steps:
    1. From the navigation area, click Service Management.
    2. In the right work area, go to the Connectivity section and click Manage Serviceable Event Notification.
    3. On the Customer Notification panel, click SNMP Trap Configuration.
    4. Ensure that the customer-supplied trap destinations are listed. Click on each of the destinations, select Change and verify that the required events are selected for notification.
      Note: To test SNMP notification, make sure that Problem Log Entry Created is selected.
    5. Click OK.
  3. Did the customer receive an SNMP event from the HMC?
    • Yes, the problem is resolved.
    • No, continue with the next step.
  4. Verify if a Problem Log Entry (Serviceable Event) was created. Perform the following steps:
  5. Was a serviceable event created with an SRC of BEB20010?
    • Yes, continue with the next step.
    • No, contact your next level of support.
  6. Attempt to 'ping' the SNMP server(s) as specified on the Customization worksheets. Perform the following steps:
    1. From the navigation area, click HMC Management.
    2. In the right work area, go to the Operations section and click Test Network Connectivity. The Test Network Connectivity window opens.
    3. Type the gateway IP address in the input field.
  7. Was the 'ping' test successful?
    • Yes, continue with step 9.
    • No, continue with the next step.
  8. The ping test might have failed because of customer firewall settings. Check with the customer to ensure that they have not chosen to block 'ping' through the customer firewall. If that is not the case, go to MAP6580 Customer Ethernet connection problem.
  9. It appears that there is connectivity to the SNMP server and that SNMP configurations settings are correct.
    1. Ask the customer to verify that SNMP traffic is not being blocked by a customer firewall.
    2. Ask the customer to test the customer SNMP server with events from another source.
    3. If none of the above resolve the problem, contact your next level of support.
