I have installed Centos 4.3 64bit with Kernel 2.6.9-34 using a driver disk for 3ware raid controller. I had partitioned this raid disk with Parted, and made ext3 file system on it. mounted and updated in /etc/fstab. It automatically mounts when I reboot the machine. Now when I do an up2date and update the kernel to 2.6.9-34-0.2 the system doesn’t recognize the raid disk. I have checked the /lib/modules/2.6.9-34.0.2.ELsmp/kernel/drivers/scsi folder and found the files 3w.9xxx.ko and 3w.xxxx.ko. But when the system boots with the new kernel it doesn’t detect the 3 ware Raid disk.
you need to move the updated 3ware driver .ko into the newer kernel's initrd. just copy the drive over, and rerun mkinitrd manually. Scan the mkinitrd docs, that will give you a good idea of what needs to be done.
