说明

  • Open a browser session to the vSphere Web Client and authenticate with an administrator account.
  • Browse the inventory to find the PowerProtect Appliance (PPDM) and take a virtual machine snapshot.
  • Launch the VMware Remote Console window for the PowerProtect Appliance.
  • Select the "Restart Guest OS" option for the PowerProtect Appliance.
  • While rebooting, press the "ESC" button in order to access the GNU GRUB boot loader screen.

  • Select the first option and type "e" to edit the boot command. (NOTE: Hold the Shift key if the GNU GRUB options screen is not loading)


  •  In the GNU GRUB boot loader page, add the option to start a bash shell with write permissions in the Linux line (See screenshot): rw init=/bin/bash

  • Press "CTRL+x" to boot the appliance in single user mode with the new Linux kernel option.
  • Type the passwd command to set the new root password: passwd

  • Restart the PowerProtect appliance: reboot
  • If the reboot command does not work (error = "failed to talk to init daemon"), use the force option:  sudo systemctl reboot --force --force
