can not login to the physical server

[hsarva]

Hello Guys, 

I can not login(tried user and root ) into the physical server on HP blade and I tried "cold boot" but I could not make it.  Can you please help me login or change the password for user or root .

   Not a very detailed description of anything.  Which hardware model?
Which OS are you running?

   There are forums for each hardware type and OS, almost any of which
would probably be more helpful than this "General Feedback and
Suggestions" forum.

   As usual, showing actual commands with their actual output can be
more helpful than vague descriptions or interpretations.
