I have 3 ESXi 6.7.0u3 hosts and trying to make vsan cluster. After configuring networking, and start setting up cluster on first host:
esxcli vsan cluster new
result:
[root@srv1:~] esxcli vsan cluster get
Cluster Information
Enabled: true
Current Local Time: 2020-09-02T11:46:22Z
Local Node UUID: 5f4630de-4f35-4760-fd8f-9440c92e6eb8
Local Node Type: NORMAL
Local Node State: MASTER
Local Node Health State: HEALTHY
Sub-Cluster Master UUID: 5f4630de-4f35-4760-fd8f-9440c92e6eb8
Sub-Cluster Backup UUID:
Sub-Cluster UUID: 52cffc95-a360-d292-7279-b6304d366ae5
Sub-Cluster Membership Entry Revision: 0
Sub-Cluster Member Count: 1
on the other 2 hosts:
esxcli vsan cluster join -u 52cffc95-a360-d292-7279-b6304d366ae5
result cluster has 3 members:
[root@srv1:~] esxcli vsan cluster get

As soon as I add storage, it doesn’t matter on which of the 3 hosts, the host is not in the cluster anymore:
[root@srv1:~] esxcli vsan storage add -s mpx.vmhba0:C0:T64:L0 -d mpx.vmhba0:C0:T66:L0 -d mpx.vmhba0:C0:T67:L0 -d mpx.vmhba0:C0:T68:L0 -d mpx.vmhba0:C0:T69:L0

Any clues what causes this, and how to solve?
