Hi, all!
I want to change current RHEL 4.0 ES into CentOS 4.2 on Sun X4100 server. The server has SAS SCSI based two 2.5" hard disks. I could only install RHEL 4.0 Update 1 because the server is equipped with RHEL 4.0 Update 1's device driver only.
This means that you installed a driver when you installed the OS ... do you still have the RHEL kernel what shipped with update 1 .. or have you upgraded the kernel since then.
Have you done any other updates (besides the kernel) since update 1?
What is the output of this command:
uname -a
I've included below the boot process messages concerned with SCSI controller. If it's possible for me to install CentOS 4.0 on my X4100, I am ready to switch to it.
TIA

More important than anything else is figuring out what kernel you need to use. There is a forzen CentOS-4.1 tree at http://vault.centos.org that has all the 4.1 kernels.
(In CentOS ... 4.0 is the original release, 4.1 is update 1, 4.2 is update 2, etc.)
After the kernel issues are defined, a plan for doing a switch can be put together. Is there a driver source so that you can build a new driver for new kernels (if required)?
