I need to build a Centos ISO with a 3.2 Kernel to setup a new server, how I can do this?
The server has a Raid Controller that's not supported in previous Kernel Versions, which means I can not install Centos 6.3 and change later the Kernel as the HDD are not showed.
Check with the RAID card manufacturer to see if they have a driver disk available for RHEL/CentOS installations. There is a driver disk functionality in the RH installer that allows modules for unsupported hardware to be inserted at install time.
Sometimes the manufacturer of the server provides the enhanced driver.
Are you even sure that this RAID controller is supported by CentOS in general?
Can you provide the server manufacturer and RAID card model?
