Tested using vSphere version 5.5.
1. Download Gparted and create a bootable usb or mount the ISO file via the iLO/iDrac.
2. Once in Gparted you need to look for two 250MB paritions, shown below:
3. Open a terminal window and type the following commands:
sudo su mkdir /boot /temp mount /dev/sda5 /boot cd /boot cp state.tgz /temp cd /temp tar -xf state.tgz tar -xf local.tgz rm *.tgz cd etc
4. Now we need to edit the shadow file and remote the password. Use vi or nano to open shadow:
vi shadow
or
nano shadow
5. You will then see a file similar to below, you want to remove the data between the first two colons for root:

6. Save and exit
7. Now run the following commands:
cd .. tar -cf local.tgz etc/ tar -cf state.tgz local.tgz mv state.tgz /boot umount /boot reboot
8. Boot back in to Gparted and follow steps 3-7 for the other parition.
9. Once rebooted and back in vSphere DCUI you should be able to log in with username root and a blank password. You can then go in and set the password you require. <comments />
