Check dayone.log on VxRail manger, do-host query data failed due to it cannot connect to host 9090 port via host IPv6 address fc00:xxxxxxxxx

Cause

IPv6 Auto-configuration is enabled on ESXi hosts and TOR switch, so the ESXi host vmk0 is configured with Auto-configuration IPv6 address fc00:xxxxxxxxx

As a result, VxRail manager cannot communicate with host vmk0 fc00:xxxxxxxxx via VxRail manager eth1 link-local address fe80:xxxxxxxxx.

Resolution

VxRail will fix this issue in future release to let VxRail manager only communicate to host vmk0 link-local IPv6 address.

Before the fix is available, please perform below steps as a workaround.

1. Login vSphere host client UI, edit vmk0 and set IPv6 Auto-configuration to "No".

2. Restart loudmouth service on ESXi host 
/etc/init.d/loudmouth restart

3. Repeat step1 and step2 on each host.

4. SSH to VxRail manger and restart loudmouth service by below command via root user 
service vmware-loudmouth restart

5. Run below command on VxRail manager to check loudmouth output, make sure each host only has one IPv6 address starts with "fe80" 
/usr/lib/vmware-loudmouth/bin/loudmouthc query

6. Lauch cluster deployment UI again.
