Configure an Appliance to Display the GRUB Menu at Boot Time

You must configure an NSX-T Data Center appliance to display the GRUB menu at boot time if you want to reset the root password of the appliance.

Important: If the configuration is not performed after deploying the appliance and you forget the root password, resetting it is not possible.

Procedure

1. Log in to the VM as root.
2. Change the value for the parameter GRUB_TIMEOUT in the /etc/default/grub file.
   GRUB_TIMEOUT=2
3. (Optional) Generate a new password by running the following command:
   grub-mkpasswd-pbkdf2
4. (Optional) Replace the existing GRUB password in the /etc/grub.d/40_custom file.
   The default password is VMware1.
5. Update the GRUB configuration.
   update-grub
