Tape, Disk, and CD-ROM Support

Tape drive support is available to the Mylex Disk Array Controller under
NetWare by means of the NWTAPE.CDM. Most NetWare applications that
communicate through ASPI on the server will work with the controller when
the NWASPI.CDM module is loaded. Disk drive support is provided through
the SCSIHD.CDM module.

Manual No. 775079 2-1

Installing the Mylex Disk Array Controller as the Primary NetWare 4.2 Controller

Similar to tape drive support, the controller also supports CD-ROM for use
under NetWare. The SCSICD.CDM provides support to the CD-ROM
application running on the server. A CD-ROM driver will also have to be
loaded. These are included with the Novell NetWare releases.

Installing the Mylex Disk Array Controller as the
Primary NetWare 4.2 Controller

If the Mylex Disk Array Controller will be the primary (bootable) controller,
you must install the controller driver at the time of NetWare 4.2 installation.

Installing NetWare 4.2 Drivers

NetWare version 4.2 is available on CD-ROM. Drivers provided in the \DOS
subdirectory of the NT4/NW Drivers Software Kit diskette (packaged with
the Mylex Disk Array Controller) are required to install NetWare 4.2 from a
CD-ROM drive connected to a Mylex Disk Array Controller.

The procedure below assumes that the CD-ROM drivers are available.

1. Boot the system from a newly created DOS boot drive, and then create
(or edit) the CONFIG.SYS and AUTOEXEC.BAT files to include the
drivers required for accessing the CD-ROM as a logical drive under
DOS. The following example assigns the CD-ROM as drive D: under
MS-DOS 6.00 or above. CONFIG.SYS contains the statements:

device = [pathname]\aspidac.sys

device = [pathname]\btcdrom.sys /D:[devicename]

AUTOEXEC.BAT contains the statement:

[pathname]\mscdex /v /m:10 /D:[devicename]

The device name is that of the specific CD-ROM drive
(e.g., MSCD001).

2. Boot the system with the new CONFIG.SYS and AUTOEXEC.BAT,
and make sure the NetWare CD-ROM files are accessible under DOS.

3. Follow the standard NetWare 4.2 upgrade or installation procedure, as
described in the NetWare 4.2 documentation.

4. Insert the DOS-formatted NT4/NW Drivers Software Kit diskette into
the floppy disk drive when the installation program prompts you to

2-2 PCI Disk Array Controller Drivers Manual

NetWare

insert the vendor-supplied disk. The installation program will scan the
diskette for all available drivers. Select the NetWare 4.2 driver from the
list:

MDAC.HAM

Installing Peripherals Under NetWare 4.2

Non-disk peripheral devices, such as tape or CD-ROM drives, can be
installed on any channel of the controller. Each disk or non-disk device will
require a unique SCSI ID, different from any other device connected to the
same channel.

Each device requires a driver module connecting it to the DAC adapter.
These modules are best loaded in the STARTUP.NCF file before the
MDAC.HAM driver.

The common devices and required modules are:

SCSI disk drives SCSIHD.CDM

(including Mylex RAID
system drives)

SCSI CD-ROM SCSICD.CDM

SCSI tape drive NWTAPE.CDM

Magneto optical drive SCSIMO.CDM

DLT t ape d rive DLT TA PE . CDM

Creating a Driver Diskette for SCO UNIX

Creating a Driver Diskette for SCO UNIX

Before installing the Mylex Disk Array Controller Drivers for SCO UNIX,
a SCO UNIX driver diskette must be created according to the instructions in
Appendix A, “Creating PCI Driver Installation Diskettes.”

This diskette will be used in both the primary and secondary installation
processes and when updating a previously installed driver wherever
instructed to insert the “Software Kit SCO OpenServer Driver diskette.”

5-2 PCI Disk Array Controller Drivers Manual

SCO OpenServer

Installing the Mylex Disk Array Controller as the Primary Controller

This section provides guidelines for the system administrator to follow
during the installation of SCO UNIX to prepare it for using the Mylex Disk
Array Controller (DAC) as the primary controller. The following guidelines
will focus mainly on the important steps for installing the SCO UNIX
drivers. For detailed information about the operating system installation,
consult the SCO UNIX documentation.

If a tape drive connected to the controller is being used for installation, make
sure that the tape drive is set to SCSI ID 2, that the configuration utility has
been run with the tape drive installed, and that the configuration has been
saved. The same is also true when using a CD-ROM, except the CD-ROM
needs to be set to SCSI ID 5.

Prepare the system to receive the SCO OpenServer 5.0.x driver by
performing the following procedure:

1. Insert the OpenServer Boot Disk into the primary floppy and boot the
system. The following prompt will be displayed:

Boot
:

2. Type ahslink at the colon(:) and press <Enter>.

: ahslink ↵

When running SCO 5.0.x on a system with an additional SCSI
controller, to install the controller at the boot prompt, enter:

Boot: defbootstr ahslink=mdac Sdsk=mdac(0,0,0,1)

If installing onto a system that is SISL capable and using a SISL
capable DAC, it is recommended to disable the SCSI chip driver on the
system by entering the following at the boot prompt:

Boot: defbootstr ahslink=mdac Sdsk=mdac(0,0,0,1)

disable=[scsi chip driver name]

3. The system will display the following message

What packages do you need linked in the system,
or q to quit?:

5

S
C

4. The system then displays standard UNIX messages, such as loading
Kernel fd(64) UNIX.text, UNIX.data, UNIX.bss, etc.

The system will then provide the following message prompt:

Please insert the fd(60)mdac volume and press
<Return>
or 'q' to quit

5. Insert the Software Kit SCO OpenServer Driver diskette into the
primary floppy drive and press <Enter>:

☛ Note

When installing SCO OpenServer 5.0.x, you will be
asked if you would like to try a replacement of the
existing mdac package. Type ‘r’ for try replacement.

6. Follow the standard SCO UNIX installation procedure until you see the
following message:

Please insert (mdac) package BTLD disk into the
floppy drive so that it can be extracted onto the
hard disk for incorporation into the link-kit.

This is where the driver package diskette is inserted a second time.

7. Insert the Software Kit SCO OpenServer Driver diskette and press
<Enter>. The system will respond with the following message:

Extracting BTLD distribution for mdac...

8. From this point forward, follow the standard procedure for SCO UNIX
installation. Make sure the entire Extended Utilities of SCO UNIX are
installed. Near the end of the installation, the following description is
displayed:

The following packages are on this disk:

NAME DESCRIPTION

mdac <Mylex Controller Description>

Please enter the names of the packages you wish to
install, or 'q' to quit
[default: mdac]:

-or-

** Press any Key to Reboot **

where [controller] is the base model of the controller.

10. This concludes the installation of SCO UNIX and the Mylex Disk
Array Controller driver. Reboot the operating system from the System
Drive that was just installed.

Installing Additional Mylex Disk Array Controllers

The driver for both the primary controller and any secondary controllers are
installed simultaneously as a part of the previous SCO UNIX installation. No
further procedures are required in order to use additional Mylex Disk Array
Controllers as secondary controllers in the installation.

Installing Mylex Disk Array Controller Tape Drivers

The driver that provides support for tape drives also gets installed as a part of
the standard controller SCO UNIX driver installation. It is recommended
that a tape drive installed on any Mylex Disk Array Controller channel be set
to SCSI ID 2.

To install UNIX from a tape drive, follow the standard SCO UNIX
OpenServer installation for tape as described in the SCO UNIX
documentation.

After SCO UNIX 5.0.x is installed, the tape drive is configured as a standard
tape device, and can be accessed by using the device /dev/rStp0. Also, any
tape control operation can be done using the tape command. Refer to the
SCO UNIX manuals for more details on using a tape drive.

If the installation of UNIX was not done from tape, use the mkdev tape
command to configure the tape drive. When prompted for the LUN of the
device, make sure to specify a LUN of 0.

Installing Mylex Disk Array Controller Tape Drivers

The tape drive may be placed on any channel. However, if another device
with the same SCSI ID is present on a lower channel, the tape may not
function properly.

Mylex Disk Array Controller CD-ROM Drivers

The driver that provides support for CD-ROM devices also gets installed as
a part of the standard controller SCO UNIX driver installation. It is
recommended that a CD-ROM drive installed on any controller channel be
set to SCSI ID 5.

Use the View/Update Configuration option of the Mylex Disk Array
Controller Configuration Utility to configure the CD-ROM. Save the new
configuration before trying to use the CD-ROM under SCO UNIX.

To install UNIX from a CD-ROM drive, follow the standard SCO UNIX
OpenServer installation instructions for CD-ROM. A screen will prompt you
for the type of installation being performed. You can choose either TAPE
(default), or CD-ROM, etc. From here you can select the SCSI option as
described in the SCO UNIX documentation.

If UNIX was not installed from CD-ROM, then a CD-ROM drive may be
configured using the mkdev cdrom command. The LUN of this device should
always be set to 0.

A CD-ROM drive may be placed on any channel. However, if another non­disk device with the same ID is present on a lower channel, only the non­disk device on the lower channel will be accessible.

Installing the Mylex Disk Array Controller as a Secondary Controller

This section provides guidelines for the system administrator to follow
during the installation of SCO UNIX to prepare it for using the Mylex Disk
Array Controller as a secondary controller. The following guidelines will
focus mainly on the important steps for installing the Mylex Disk Array
Controller SCO UNIX drivers. For detailed information about the operating
system installation, consult the SCO UNIX documentation.

If a tape drive connected to the controller is being used for installation, make
sure that the tape drive is set to SCSI ID 2, that the configuration utility has
been run with the tape drive installed, and that the configuration has been
saved. The same is also true when using a CD-ROM, except the CD-ROM
needs to be set to SCSI ID 5.

Secondary Controller Installation Procedure

The procedure for installing the Mylex Disk Array Controller as a secondary
controller under SCO UNIX using Mylex drivers varies slightly depending
on the type of device that is installed as the primary controller:

• If the primary controller is IDE or EIDE, start at Step 1.

• If the primary controller is SCSI, start at Step 6.

1. Make sure the following SCO SCSI modules are enabled before
attempting to install the Mylex controller SCO mdac drivers into an
existing SCO system.

Sdsk :SCSI disk
Stp :SCSI tape
Srom :SCSI CD-ROM

2. Change to the sdevice.d subdirectory

# cd /etc/conf/sdevice.d

3. Enable the SCO UNIX SCSI modules by editing the files: Sdsk, Stp,
and Srom. Change the second field on all three files from N to Y.

Example of Sdsk file before edit (where x could be any digit):

Sdsk N xxxxxxxx

After edit:

Sdsk Y xxxxxxxx

Tuning SCO for Maximum Performance

Best system performance can be achieved when using the Mylex Disk Array
Controller SCO UNIX mdac driver by fine-tuning certain UNIX parameters.

To perform this system tune-up, use the scoadmin utility. Select Hardware/
Kernel manager. Under the Kernel option select Tune Param eters . The
SDSKOUT parameter is located under Miscellaneous device drives and

hardware parameters and the NMPBUF parameters is located under Buffers
management. Refer to the SCO UNIX on-line documentation for

information on the scoadmin utility.

Manual No. 775079 5-11

Installing Mylex Disk Array Controller Tape Drivers

Tune the following parameters:

SDSKOUT – Set this value to a number equal to 126 divided by the number
of system drives being used. If required, round down the result to the next
lower value so that its multiple does not exceed 126.

NMPBUF – Set this parameter for controller driver version 4.x or above.

Use the sar -h command to find the Scatter/Gather Buffer utilization and the
Out of scatter/Gather buffers condition to set the buffer parameters.

Since the system configuration and the test suites differ significantly, the
best way to tune either of these parameters is to evaluate the system activity
report data. Refer to the SCO UNIX documentation for more information on
methods and procedures that relate to acquiring and interpreting sar data.

Changing the Controller Configuration

If there is a need to change the IRQ of the controller at any time, refer to the
UnixWare manual under DCU. If a Mylex Disk Array Controller is the
primary controller, and a second, third or fourth Mylex Disk Array
Controller is to be added, set the interrupt for the secondary controller, then
power-cycle the system (power off, then power on).

When the system restarts, UnixWare identifies the controller and displays
the message “New hardware instance mapped to static driver...” The
controller should be detected automatically during the start up sequence.
Use DCU to verify the interrupts after logging-on the system.

Creating a Driver Diskette for Solaris

Creating a Driver Diskette for Solaris

Before installing the Mylex Disk Array Controller Drivers for Solaris,
a Mylex MDAC Supplemental Driver Diskette (MDAC Supplemental
Diskette) must be created according to the instructions in Appendix A,
“Creating PCI Driver Installation Diskettes.”

This diskette will be used in both the primary and secondary installation
processes and when updating a previously installed driver wherever
instructed.

How to use the Mylex Supplemental Driver Diskette

You can use the Mylex Supplemental Driver Diskette you just created in the
previous section in one of two ways:

• To use new drivers to install or upgrade the Solaris operating
environment on a system with new hardware (primary installation), or

• To add new drivers to support (update) new hardware on an already
installed booted system (secondary installation).

Installing Solaris Using the Solaris Device
Configuration Assistant Diskette for a
Primary Installation

The steps below describe how to use drivers on the Solaris Device

Configuration Assistant Diskette
(Intel Platform Edition) on a new system.

These instructions assume that you are installing Solaris 7 onto a x86 system
using the Mylex MDAC driver.

Use the appropriate Solaris Device Configuration Assistant Diskette as the
boot diskette.

1. Insert the Solaris Device Configuration Assistant Diskette into your

computer’s disk drive. Also, insert the Solaris Installation
CD-ROM. If you have a network installation, verify with your system
administrator that the Solaris Network Installation image is available
on your network.

2. Turn on your computer.

3. When the Solaris Device Configuration Assistant screen is displayed,
choose the F4 option (on Solaris 7, this is labeled as, F4_Add Driver).

You will see the Bus Enumerating screen with the following message:

Determining buses...is displayed.

4. Follow the directions on the next screen, the Install Supplemental
Drivers screen.

5. Now, remove the Solaris Device Configuration Assistant Diskette from
the disk drive, then insert the MDAC Supplemental Diskette.

6. Press <F2> to continue. (F2 means “Continue”)

The Select Solaris System Version screen is displayed. Press <Enter>
to choose the Solaris operating system. It will show up as:

[ ] Solaris OS 2.7

7. Select the appropriate Solaris Operating System and press <F2>.
Two screens will be displayed.

• The Loading Supplemental Driver Software screen is displayed,

along with a progress bar that shows the percentage of drivers that
have been extracted from the diskette. Drivers are read into memory
and survive long enough for the system to successfully boot to its
installation program. The drives loaded are:

mlx.itu and mdac.itu

• The Continue Supplemental Driver Installation screen is displayed

when all the new drivers on the diskette have been processed.

10. Press <F2> to continue.

 Caution

DO NOT REMOVE the Solaris Device Configuration
Assistant Diskette from the disk drive until you see
the following message displayed in a dialog box:

Message: If you want to bypass the device
configuration and boot screens when the system
reboots, eject the Solaris Device Configuration
Assistant/Boot diskette now.

11. Continue with Sun Microsystems’ installation instructions and follow
the screen prompts.

12. Near the end of the Solaris operating system installation, you will be
asked to insert the Mylex Supplemental Driver. Insert the diskette at
that time.

The system will automatically reboot when the Solaris operating
system has been completely installed.

Installing Solaris Using the Mylex MDAC Supplemental Driver Diskette for a Secondary Installation

Before you begin to add or update your drivers, check that your newly
supported hardware devices are installed and configured according to the
instructions in the corresponding Device Reference Page, if any. See Device
Reference Manual for Solaris (Intel Platform Edition).

These instructions assume that you are working with a x86 system using
either the Mylex MDAC driver.

☛ Note

When the Solaris Intel Platform Edition software is
already installed, the simplest way to add new or
updated drivers is to install the supplemental driver
diskettes as patches on your system.

Follow the steps below for a secondary (existing) installation.

release directory (sol_27 for Solaris 7). For example:

# /mnt/DU/sol_27/i86pc/Tools/install.sh -i

The install.sh script searches for all new or updated drivers on the
diskette. When a new or updated driver is found, the following message
is displayed:

Unconditionally installing ITUs <mlx mdac>
Installing package <MYLXmlx>

7. You will see the following message:
