This article describes how to troubleshooting the issue
Issue: vSan network alarm 'vSan MTU check (ping with large packet size)'
vSan network alarm 'vSan basic (uncast) connectivity check.
vSan network alarm 'vSan cluster partition"
I recently encountered the issue, witness host and esxi hosts are not communicating each other.
Troubleshooting steps:-
> Login any one of esxi host in cluster and run the below command. > esxcli vSAN cluster get
> Here, witness host not showing on vsan cluster due to connectivity issue.
> # esxcli vsan network list
it showing vsan adapter list which has enabled services on esxi host.
# esxcli vsan cluster unicastagent list
> But we enabled different vmk adapter for witness host communication on each esxi host.
> To fix the issue, we ran the below command on each host
# esxcli vsan network ip add -i vmk6 -T=witness
> After that, it started communicating each other and showing correct information on each host .
> Run the below command again, now showing another adapter also on host
# esxcli vsan network list
