Data Domain: How to manually clear alerts

PURPOSE: Determining the current alerts on the Data Domain and clearing the alerts manually using command line and Web Interface.

APPLIES TO:

• All Data Domain Systems

• All Software Releases

PROBLEM: To clear any transient alerts on the Data Domain before starting DDOS upgrades, as upgrades should proceed without active alerts.

SOLUTION USING THE DD CLI:

1. Connect to the DDOS command line through SSH or the serial console.
2. Verify the list of current alerts: 

   # alerts show current

3. Clear the alert manually by running this command: 

   # alerts clear alert-id <alert-id-list>

4. Verify that the alerts have successfully been cleared by checking the current alerts again: 

   # alerts show current

5. You can view the status of the cleared alert in the alerts history by running this command: 

   # alerts show history 

SOLUTION USING the DD Web Interface or UI:

1. Connect to the DDOS Web Interface or UI through a browser.
2. To view all the current alerts, select Health > Alerts > Current Alerts.
3. To limit the number of entries in the current alert list, do the following.
   A. In the Filter By area, select a Severity and Class to expose only alerts that pertain to those choices.
   B. Click Update.
   All alerts not matching the Severity and Class are removed from the list.
4. To display additional information for a specific alert in the Details area, click the alert in the list.
5. To clear an alert, select the alert checkbox in the list and click Clear. A cleared alert no longer appears in the current alerts list, but it can be found in the alerts history list.
6. To remove filtering and return to the full listing of current alerts, click Reset.
