Booting to GRUB and requiring username and password to continue booting in VCF Operations for Networks

Products

• VCF Operations for Networks

Issue/Introduction

Performing a reboot of platform or collector appliance(s) and continuing to both boot options require username and password and then will prompt for password.

Upon boot you see a screen with "GNU GRUB" and the menu options:

• Ubuntu
• Advanced options for Ubuntu

and a prompt to "Enter username:"

NOTE:  VCF Operations for Networks was formerly named Aria Operations for Networks (AON), and prior to that was named vRealize Network Insight (vRNI).

Cause

 The /boot/grub/grub.cfg file is missing the --unrestricted flag on the menu entry, which enforces authentication for all boot options.

Resolution

1. Access the appliance console.
2. Edit the /boot/grub/grub.cfg file.
3. Locate line 156 (for the relevant menuentry section).
4. Append the --unrestricted flag to the menuentry line.
5. Confirm the line reads:

   menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple<UUID>' --unrestricted 

6. Save the file and reboot the appliance.
