Description

This procedure explains how to change GCP CVO DNS IP address.

Procedure

WARNING

DNS change can have a very slightly impact, which can happen if a dns query arrives during the modification time (which normally takes couple of milliseconds). Hence for highly productive and sensitive systems we recommend to schedule a maintenance activity for the change.
  1. Connect to the cluster via SSH and switch to advanced mode (set advanced)
  2. dns modify -vserver <vserver> -domains <domains> -name-servers <name_servers>
  3. vserver services name-service cache hosts forward-lookup delete-all -vserver <vserver>
  4. vserver services name-service cache hosts reverse-lookup delete-all -vserver <vserver>

Note: DNS services can be tested with vserver services name-service getxxxbyyy commands.
