Creating SNMP alert notifications—originating from the event monitor

The MD storage management software can notify you when the status of a storage array or one of its components changes. This is called an alert notification. You can receive alert notifications by three different methods: email, SNMP traps originating from the storage management station where the event monitor is installed, and SNMP traps originating from the storage array (if available). This topic describes how to create SNMP traps originating from the event monitor.

To configure an SNMP alert notification originating from the event monitor, you specify the community name and the trap destination. The community name is a string that identifies a known set of network management stations and is set by the network administrator. The trap destination is the IP address or the host name of a computer running an SNMP service. At a minimum, the trap destination is the network management station.

Keep these guidelines in mind when configuring an SNMP alert notification:
  • Host destinations for SNMP traps must be running an SNMP service so that the trap information can be processed.
  • To set up alert notifications using SNMP traps, you must copy and compile a management information base (MIB) file on the designated network management stations.
  • Global settings are not required for the SNMP trap messages. Trap messages sent to a network management station or other SNMP servers are standard network traffic, and a system administrator or network administrator handles the security issues.
  • For more specific notifications, you can configure the alert destinations at the storage management station, host, and storage array levels.
  1. Do one of the following actions based on whether you want to configure alerts for a single storage array or for all storage arrays.
    • Single storage array – In the Enterprise Management Window (EMW), select the Devices tab. Right-click the storage array that you want to send alerts, and then select Configure Alerts.
    • All storage arrays – In the EMW, select the Setup tab. Select Configure Alerts, and then select the All storage arrays radio button, and then click OK.
    The Configure Alerts dialog is displayed.
  2. Select the SNMP - Event Monitor Origin Trap tab.
    Any SNMP addresses that you had previously configured appear in the Configured SNMP addresses area.
  3. In the Community name text box, type the community name.
    A community name can have a maximum of 20 characters.
  4. In the Trap destination text box, type the trap destination, and click Add.
    You can enter a host name, IPv4 address, or IPv6 address.
  5. (Optional) To verify that an SNMP alert is configured correctly, you can send a test message. In the Configured SNMP addresses area, select the SNMP destination that you want to test, and click Test.
    A test message is sent to the SNMP address. A dialog box is displayed with the results of the validation and any errors. The Test button is disabled if you have not selected a community name.
  6. Click OK.
    An alert icon is displayed next to each node in the Tree view for which an alert is set.
