Clearing triggered alarms (legacy system)

If a legacy alarm is triggered, you can clear it instead of acknowledging it.

Before you begin

About this task

Disabling an alarm for an attribute that currently has an alarm triggered against it does not clear the alarm. The alarm will be disabled the next time the attribute changes. You can acknowledge the alarm or, if you want to immediately clear the alarm rather than wait for the attribute value to change (resulting in a change to the alarm state), you can clear the triggered alarm. You might find this helpful if you want to clear an alarm immediately against an attribute whose value does not change often (for example, state attributes).


  1. Disable the alarm.
  2. From the service laptop, log in to the primary Admin Node:
    1. Enter the following command: ssh admin@primary_Admin_Node_IP
    2. Enter the password listed in the Passwords.txt file.
    3. Enter the following command to switch to root: su -
    4. Enter the password listed in the Passwords.txt file.
      When you are logged in as root, the prompt changes from $ to #.
  3. Restart the NMS service: service nms restart
  4. Log out of the Admin Node: exit
    The alarm is cleared.
