How to set critical event alert filtering

Last Updated:

Applies to

E- Series Storage Array


This article provides the procedure to set critical event alert filtering.

The set event alert commands manage alert event notification by either disabling or enabling notification related to a specific alertable event. To prevent notification about a specific alertable event, block it. To enable notification about a specific alertable event, unblock it.

When you define your storage array, you can configure the alerts and define how the event alerts are managed. If you have configured the storage array to send alerts, a notification is sent to a designated recipient when an alertable event occurs. That notification can be one or all of the following types:

  • Email
  • Syslog
  • SNMP trap notifications

The set event alert CLI commands work on a single storage array. When the commands are run on a storage array, only that storage array is affected by the commands. Other storage arrays that have not had the CLI command run against them have the default behavior.


  • Blocking an event alert does not prevent the event from being posted to the system event log. All events continue to be posted to the event log.
  • Non-alertable events cannot be made alertable using this command.

In the event, where hundreds/thousands of critical alerts are reported every day, temporarily suspend the critical alerts, until the issues are resolved from a Technical Case.
