help me friends
i am new to field of Red hat ,i just installed linux server virtulaziation
but i am not able to configure my wifi setting and it does not show me the other drive that is present in my system

Can you confirm the exact distribution you are using, "Red Hat" refers to a legacy Distribution. Do you mean Red Hat Enterprise Linux or something else? It might be however the Drivers for the wifi are not installed, when you say you are unable to configure it, is it detected/listed or not?

Are you sure it does not see your other drive? It's more likely just not mounted, if you could confirm by doing "ls /dev/ | grep sd". This should list the active drives + partitions that the server can see (assuming you are using SATA/SAS based drives)

please inform us as to what version you are using

and also CALL your paid for tech support
Red Hat Enterprise Linux is not free
you NEED to buy a license
