Published: 25 Feb 2021 Last Modified Date: 08 Jul 2022
Issue
Ask Data process failed to start up after some topology change is made, for example adding a new node on Tableau Server
Environment
Tableau Server
Resolution
Use [netsh interface ipv6 show prefixpolicies] command to check the current precedence of multiple IP addresses, and use [netsh int ipv6 set prefixpolicy] command to modify the precedence.
Below is an example where IPv6 ispreferred over IPv4. Precedence Label Prefix ---------- ----- -------------------------------- 50 0 ::1/128 40 1 ::/0 35 4 ::ffff:0:0/96 30 2 2002::/16 5 5 2001::/32 3 13 fc00::/7 1 11 fec0::/10 1 12 3ffe::/16 1 3 ::/96
To change the precedence to make sure IPv4 is preferred, you need to execute the following steps: a) Run [tsm stop] command to stop Tableau Server. b) Run the following commands to adjust precedences of IP addresses. netsh int ipv6 set prefixpolicy ::ffff:0:0/96 50 0 netsh int ipv6 set prefixpolicy ::1/128 40 1 netsh int ipv6 set prefixpolicy ::/0 30 2 netsh int ipv6 set prefixpolicy 2002::/16 20 3 netsh int ipv6 set prefixpolicy 2001::/32 5 5 netsh int ipv6 set prefixpolicy ::/96 1 4 c) Reboot OS to restart Tableau Server administrative services. d) Run [tsm start] command to start up Tableau Server.
Cause
IPv6 address is preferred to IPv4 address.
Additional Information
Also use [netsh interface ipv4 show interface] command to check if there is multiple NICs and they are in expected order.
