Configuring the NSX-T Data Center appliance to display the GRUB menu at boot time is required to reset the root password of the NSX-T Data Center appliance.

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

Procedure

  1. Log in to the VM as root.
  2. Change the value for the parameter GRUB_HIDDEN_TIMEOUT in the /etc/default/grub file.
    GRUB_HIDDEN_TIMEOUT=2
  3. (Optional) Change the GRUB password in the /etc/grub.d/40_custom file.
    The default password is VMware1.
  4. Update the GRUB configuration.
    update-grub
