<div id="body1547193420658"><div class="section" id="ALM-12072__section626017484164"><h4 class="sectiontitle">Description</h4><p id="ALM-12072__p15433448121614">HA checks the floatip resources of Manager every 9 seconds. This alarm is generated when HA detects that the floatip resources are abnormal for 3 consecutive times.</p>
<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 FusionInsight Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby switchover.</p>
