Solaris : Determine WWN for HBA Cards, without fiber connection

Ramdev

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/

    Hi Ramdev,

    Just being rookie as linux admin, would like to prepare for RHCE certification. Kindly suggest on how to go with self preparatory.. Thanks

    • Ramdev says:

      Hello siva, for your self learning I would recommend you to prepare your home setup with virtualbox from virtualbox.org) and download oracle Linux from oracle site ( it is having same kernel and packages as rhel). Go through the access.redhat.com site and create a normal account for the free articles and information on course curriculum. All the best. I will try to add clear setup information sometime next week.
