Chapter 5: OS Installation
C. Existing System Installation
Adding or Updating the C8XX Package for LSI SCSI controller. Before you
install the C8XX driver, make a backup copy of the existing kernel:
1. Log on as root.
2. At the shell prompt, type:
# cp /stand/unix /stand/unix.safe
Use this copy of the old kernel to reboot the system if the driver
installation fails. Refer to Troubleshooting for more information.
3. Once the old kernel is saved, insert the “PCI SCSI SCO UnixWare
driver” diskette.
4. Load the driver using the pkgadd command by typing:
# pkgadd -d diskette1
5. Select C8XX and press Enter. The C8XX driver is then loaded onto
the system.
6. The system will again prompt you to load a driver even if loading was
successful. Type q (quit) and press Enter.
7. Verify that the driver is now loaded successfully by typing:
# pkginfo c8xx
8. The package information should look like this: “system c8xx Symbios
IHV HBA”
9. After the C8XX package is loaded, a message indicating a system
reboot is necessary may appear. To reboot the system, type the
following command:
# init 6
During the boot process, the driver scans the SCSI bus and lists the
devices found on it. If the kernel panics during boot, then reboot the
system with the saved copy of the old kernel. Booting from the saved copy
of the kernel is described in the following section titled “Troubleshooting.” If
the reboot is successful, the system is ready to use.
