    If any service activity is required, a notification is sent. Event reporting process The following methods are used to notify you and the IBM Support Center of a new event: v If you enabled Simple Network Management Protocol (SNMP), an SNMP trap is sent to an SNMP manager that is configured by the customer.

  • Page 130: Describing The Fields In The Event Log

    Event notifications Storwize V7000 can use Simple Network Management Protocol (SNMP) traps, syslog messages, and Call Home email to notify you and the IBM Support Center when significant events are detected. Any combination of these notification methods can be used simultaneously. Notifications are normally sent immediately after an event is raised.

  • Page 131: Power-On Self-Test

    Each event that Storwize V7000 detects is assigned a notification type of Error, Warning, or Information. When you configure notifications, you specify where the notifications should be sent and which notification types are sent to that recipient.
