Just to give a bit more details, adaptec 1420 SATA2 Raid is not supported by CentOS by default, I have compiled and driver disk.
While running yum update, I notice there are a couple of kernel related updates. (Not sure if the kernel I have in my cd is the latest since I download it 5-6 weeks ago.) I wonder if the Raid driver died because of the kernel update?
How can I tell? How do I troubleshoot this issue?
I am a newbie, thus any suggestions and advice will be appreciated.
