Setup Event Notification

Overview

Operating Procedures

Overview

This function specifies whether to report events that are detected in the storage system.

There are five methods for event notification: Host Sense Key Code Qualifier, SNMP Trap, E-Mail, syslog, and REMCS.

A notification setting can be selected for each type of event.

Caution

For the SNMP Trap notification, performing the following functions is required.
- [Setup SNMP Agent Basic Interface]
- [Setup SNMP Manager]
- [Setup SNMP Agent MIB Access View]
- [Setup SNMP Agent User]
- [Setup SNMP Agent Community]
- [Setup SNMP Agent Trap]
For E-Mail notification, performing [Setup E-Mail Notification] is required.
For syslog notification, performing [Setup Syslog] is required.
For REMCS notification, performing [Setup Remote Support] is required.
If ETERNUS SF Storage Cruiser is used and configured to automatically obtain the component status of the storage system, event notifications by SNMP traps for the following events are automatically enabled (notified).
- Remote Path Error of no Data Transfer
- Recovery module
- Temperature restoration
- FC CA Port Link Status Changed
- iSCSI CA Port Link Status Changed
- Remote Path Recovery
- Events whose notification is enabled by default, but is disabled manually
If the storage system is deleted from ETERNUS SF Storage Cruiser, event notifications of the SNMP traps revert to the default value. However, if the event notifications of the SNMP traps are changed from a storage system after being automatically changed, the event notifications do not revert to the default value even if the storage system is deleted.

Settings

The events are classified into three levels: "Error Severity Level", "Warning Level", and "Informational Level".

Click the [Setting based on Severity] tab, [Error Severity Level] Tab, [Warning Level] Tab, or [Informational Level] Tab to display the setting fields for each level.

Setting based on Severity

Select whether to notify of an event by levels. Checkboxes are displayed for selectable notification methods.

When enabling the notification, select the method from "Host Sense Key Code Qualifier", "SNMP Trap", "E-Mail", "syslog", or "REMCS" (multiple selections can be made).

When setting the notification method for each event, move on to the setting fields for each level.
