<p id="ALM-12072__p15433154881618">This alarm is cleared when the FloatIP resource is normal.</p>
<p id="ALM-12072__p7433164891618"><strong id="ALM-12072__b4433648141611">Resource Type</strong> of FloatIP is <strong id="ALM-12072__b243317487168">Single-active</strong>. Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new FloatIP resources have been enabled on the new active <span id="ALM-12072__text34789336432">MRS</span> Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby switchover.</p>
