16.5. Changing Master and Slave Servers IP Addresses¶

If the master server IP address changes for some reason, you have to additionally configure slave servers registered with it:

1. On each slave server, open the /var/opt/pva/agent/etc/vzagent.conf file, locate the <ns1:address> and <host> elements and change the old master server IP address to the new one. For example:

   <node>
   <...>
   <host>10.30.10.101</host>
   <...>
   <ns1:address>10.30.10.101</ns1:address>
   <...>
   </node>
   

2. Restart the va-agent service to apply changes:

   # systemctl restart va-agent
   

If the IP address of a slave server changes for some reason and you want to keep its VA settings, you have to additionally configure the master server:

1. On the master server, open the /var/opt/pva/mn/etc/vzagent.conf file, locate the corresponding <ns1:address> and <host> elements with the old slave server IP address and change it to the new IP address. For example:

   <node>
   <...>
   <host>10.30.10.102</host>
   <...>
   <ns1:address>10.30.10.102</ns1:address>
   <...>
   </node>
   

2. Restart the va-mn service to apply changes:

   # systemctl restart va-mn
   

Alternatively, you can unregister the slave server from Virtuozzo Automator and re-register it with the new IP address, but in this case VA settings for this server will be lost.
