I dont know how to solve this
please help
Thanks in advance

first the current red hat is RHEL 6.4
it also is NOT a free operating system
you MUST buy the required support contract
--- there is no way around this ---
--- you have to buy it ---
-- desktop install on ONE machine
https://www.redhat.com/apps/store/desktop/

server install
based on Number of users ( could be over $6,000 )
https://www.redhat.com/apps/store/server/



buy the license or install one of the free rebuilds
CentOS 6.4
http://centos.org/
ScientificLinux 6.3
https://www.scientificlinux.org/


for RHEL 6.4
you need to install a RAID driver provided BY red hat
that you can only install with the paid subscription


CentOS has it as part of the os
that is unless this is a fake Microsoft software raid that is set up
if so turn it off
