RHEL4 / CentOS 4.x does not detect the Adaptec I2O RAID controller during installation. Affected controllers including the Adaptec 200S, 2005S, 2010S and 2015S Zero Channel SCSI RAID.
There are actually two problems with the installation
The installer does not recognize the adapter and therefore does not load the appropriate device driver. The bootloader is not installed properly so the system will not boot after installation. This symptom also occurs under Fedora Core 3.
Since the installer does not recognize the Adaptec I2O RAID controller, the driver must be loaded manually as following:
At the end of the installation, do not select Reboot. Since the installer does not create the boot loader correctly, it is necessary to perform the following steps:
# chroot /mnt/sysimage # /sbin/grub-install /dev/i2o/hda # exit
If these steps are not performed, the system will not boot. Fortunately, there is a simple procedure to fix the boot sector as described below:
# chroot /mnt/sysimage # /sbin/grub-install /dev/i2o/hda # exit # exit
