vSphere HA agent can't reach gateway ip address

[thuso607]

Good day,

My vCenter server appliance is displaying this error: "vSphere HA agent on this host could not reach isolation address 192.168.1.1".

The 192.168.1.1 is the gateway address that I have assigned on the esci host and the vCenter server appliance. what can I do to mitigate this error?

Thanks in advance.

Regards

Thuso

I think the error message is pretty clear. HA tries to ping the isolation address to ensure it can validate an isolation situation when the network has failed. That isolation address is usually the default gateway. As such the selected IP address or the default gateway, needs to be an ip-address that can be pinged from the management network!
