Cause

- while there could be multiple reasons for a failover to take place , in this particular case the reason for the failover was a system shutdown of gateway node gn1s-a-1 due to overheating.

Then the cluster starts shutting down.

-- customer talked to the data center team and they did have a cooling outage on Sunday.

Fix

- there was no need for any workaround or fix , the fsg services failed over from gn1s-a-1 to gn1-a-1

- gn1-a-1 is now the active primary and gn1s-a-1 is the supplementary primary

- reset the failover count from the NMS
