Installing the Driver When SCO UNIX is Already Installed
?To update or install the ad160 driver if SCO UNIX is already
?installed, follow the instructions in this section. The procedures are
?similar for all versions of SCO UNIX. Procedures that are specific to
?a SCO version are noted when necessary.
?Caution:
?Improper or corrupt driver updates might destroy
?your existing UNIX file system.
?Back up all important files before proceeding.
?Installing or updating the driver involves the following tasks,
?which must be completed in the order presented:
?Back up the old UNIX kernel and any other important files.
?Use installpkg to load the driver.
?Change the primary host adapter to an Ultra160 Family host
?adapter, if necessary.
?Rebuild the kernel to reflect the new changes.
?Reboot the computer with the new kernel.
?Note: To update or install the driver, you must first enter the
?Single User Mode (System Maintenance Mode). Refer to the
?SCO UNIX documentation for instructions on how to use
?the init(m) or shutdown(m) command to put the system into
?System Maintenance Mode.
?1 Perform a System Backup
?If you have not already done so, back up all important files on
?the computer by following these steps:
?Note: To back up the whole system, refer to your SCO UNIX documentation.
?a Log in as root.
?b To back up the current kernel configuration, type the
?following and press Enter after each line:
?umount /stand
?mount /dev/boot /stand
?cp /stand/unix /stand/unix.orig
?Note: If you ever need to boot up from the pre-update
?kernel, load the unix.orig backup kernel at the UNIX Boot:
?prompt. To do this, type unix.orig and press Enter.
?c This step is optional. For extra security, you may back up the
?mdevice file and the sdevice.d directory. To perform this
?backup, type the following and press Enter:
?copy -rom /etc/conf /etc/conf.bak
?2 To load the driver using installpkg, follow these steps:
?a At the UNIX system prompt, type installpkg and press
?Enter. The screen displays the following messages:
?Confirm
?Please insert the floppy disk
?:
?:
?Strike ENTER when ready
?or ESC to stop.
?b Insert the Ultra160 Family Manager Set disk for SCO UNIX
?and press Enter. The screen displays the following
?messages:
?Installation is in progress - do not remove the floppy disk.
?The following packages are on this disk:
?NAME DESCRIPTION
?ad160 Adaptec Ultra160 Family Driver for SCO
?OpenServer 5.0.5/dxx
?Please enter the names of the packages you wish to
?install, or q to quit:
?c At this point, type ad160 and press Enter. The screen then
?displays this message and various installation status
?prompts:
?Installing ad160
?When the driver is loaded, the following message appears,
?indicating that the ad160 driver has been loaded into the
?Link Kit for kernel addition:
?Installed ad160
?#
?3 Modify the mscsi file, if necessary, to change your primary
?host adapter to an Ultra160 Family host adapter, using the
?procedure below:
?a Enter the following command:
?cd /etc/conf/cf.d
?b Use a text editor to edit this file. Enter the following
?command if using the vi editor:
?vi mscsi
?c Search for all entries with the host adapter number 0 (zero).
?The host adapter number is the third column in each entry.
?For example:
?
? Host Adapter Prefix SCSI Device Type Host Adapter Number Target ID Logical Unit Number Bus*
xx Stp 0 0 0 0
xx Sdsk 0 0 0 0
xx Srom 0 0 0 0
?* This field applies to SCO OpenServer 5 and later.
?d Modify the mscsi file according to your hardware setup:
?- If you are booting from an Ultra160 Family host adapter,
?make sure the host adapter prefix for the host adapter
?number 0 is ad160.
?- If you are not booting from an Ultra160 Family host
?adapter, make sure the host adapter prefix for the host
?adapter number 0 is the appropriate prefix for each
?device on your primary Adaptec host adapter. See the
?table above.
?e Save the file and exit the text editor.
?
?
?4 Rebuild the UNIX kernel by following these steps:
?a Type the following at the # prompt and press Enter after
?each line:
?cd /etc/conf/cf.d
?./link_unix
?Status messages appear on-screen.
?b When the kernel has been built, shut down the system by
?typing shutdown-g0 and pressing Enter.
?c Turn OFF the system power when you are prompted to do
?so.
?If you need to reconfigure your system, you may do so now.
?d Add or remove host adapters or devices as needed.
?5 Boot the new kernel by following these steps:
?a Follow the onscreen instructions to reboot your system,
?usually by pressing Enter.
?b Check the host adapter BIOS messages to verify that all your
?installed SCSI devices are listed.
?If some or all of your installed SCSI devices do not
?appear at this time, your SCSI cables may be loose, or the
?SCSI device setup may not be complete. If so, go back
?and correct any problem before proceeding.
?c Wait for UNIX to boot with the new kernel.
?See the Troubleshooting section if the system crashes or if
?"panic" (UNIX error) messages are displayed at boot
?time.
?The ad160 driver for your Ultra160 Family host adapter should now
?be ready for use. |
