HI,

I am getting one error when I run the pre installation check.

Can someone please tell me what to check??

Code:

I think the errors that you are getting is in relation to ssh keys and the oracle/grid user. Make sure that you can ssh between all RAC hosts in our RAC cluster as your oracle user and grid user without using passwords.
