I am logged onto the remote console of my blade server through ILO, I have the grey and yellow screen.]
I do Alt-F1 to get to the black screen, type "unsupported" put in root password then get the prompt
I then type "vi /etc/hosts
I then add the entries I need to.
This is the bit I am having problems with...
Now I should be able to push the Escape key, get the vi command line type :wq and it will save and quit vi.
I get the exact same problem when doing this in front of the server with a physical keyboard
