The cluster replication heartbeat to peer cluster failed

[Satya_Pavan]

Hi Everyone,

In my storage system I'm getting the below alert that heartbeat to peer is failed for some time period. Kindly suggest how to check and troubleshoot the below alert. Current version is 9.7P5

alertTrap: A user-defined trap indicating a condition that should be corrected immediately, such as a failed disk.cluster.repl.peerNW.unreachable:The cluster replication heartbeat to peer cluster 786cb0c6-aa62-11ea-9d0c-000d3a2cf2d3 failed for at least 30

Output of these ?

::> cluster peer health show
::> event log show -message-name *peerNW.unreachable*

set adv:
::*> cluster peer show -fields unreachable-local-nodes

Take a look at the page 289 of the EMS Event catalog:

Also check the output of 

cluster ping-cluster -node node

Thanks for the details they are very useful to check.

We tried to re-configure the cluster ip's again but it's going unreachable after sometime and coming back online not sure what is causing this issue. Is it possible to check what causing these type of issue ?
