‭How to change the main IP address on a Compute Resource in SolusVM 2

Answer

Note: it is recommended to have an alternate option to access nodes like IPMI in case a remote connection gets lost

1. Change the IP address on the host where Compute Resource resides for br-ext bridge using native Linux tools
2. Restart the network and verify that access to the node is possible.
3. Create a backup of the current state of SolusVM 2 database:

5. Update IP address in 'host' field of compute_resources table:

   MYSQL_LIN: # update compute_resources set host='NEW_IP' where id = NODE_ID;
   UPDATE 1

   Replace NEW_IP and NODE_ID with your values.
6. Restart solus-agent service on CR node:
   # systemctl restart solus-agent
7. Verify the connection to the CR node is restored.
