Introduction

This document presents very important information that you need to install SCO UNIX.

The first section of this document is a list of helpful tips on NOS installation, the second

section is a step-by-step installation guide.

NOTE: Hewlett-Packard has more than one Disk Array Controller (DAC) for the

NetServer product family. In this document the term "HP Disk Array" refers to

the EISA and PCI Disk Array Controller models C3609A and C3610A,

respectively. The term "HP NetRAID" refers to the HP NetRAID and NetRAID-

1 PCI Adapters models D4943A and D4992A, respectively. The term “HP

NetRAID 1Si refers to model number D2140A. The term “HP NetRAID 3Si”

refers to model number D5955A. The term “HP Embedded RAID” refers to the

built in RAID controller on the HP NetServer LH 3 and LH 4.

The HP NetServer E 30 does not support either DAC.

The HP NetServer E 40 , E 45 and E 50 support the HP NetRAID DACs only.

The HP NetServer E 60 only the HP NetRAID 1Si and HP NetRAID 3Si.

SCO MPX 3.0 does not work correctly on multiprocessor systems using the Intel

Pentium Pro, Pentium II or Pentium III processor (e.g. the NetServer LC II, LC 3,

LD Pro, LH Pro, LH II, LH 3, LH 4, LPr, LX Pro, LXe Pro, LXr Pro and LXr

8000).

SCO Open DeskTop 3.0, OpenServer 3.0, and MPX 3.0 are not supported on the

NetServer LC 3, LH 3, LH 4, LXr 8000, and LXr8500.

SCO OpenServer 5.0.x is supported on the NetServer E60, E 800 LPr, LC2000,

LC3, LH3, LH3000, LH4, LXr 8000 and LXr8500

Section 1. General Tips

Introduction

The following subsections discuss problems that you may encounter when installing SCO

UNIX 3.2v4.2, Open Desktop (ODT) 3.0, OpenServer 3.0, MPX 3.0, and OpenServer

5.0.x.

SCO UNIX installation procedures include installing SCO UNIX files, loading all

required drivers (including BTLD (Boot Time Loadable Driver) packages), and linking

information to the kernel.

As a rule, select fully configurable, rather than automatic, initialization.

CaSe SeNsItIvE

All version of UNIX are very case sensitive and you need to be absolutely sure that you

type in the commands exactly as instructed. Almost all UNIX commands are in lower

case so if you are unsure try lower case first.

Start Counting At Zero

In almost all cases a UNIX system will start counting at ZERO. Therefore, SCSI

Controller 0 is the first controller, SCSI Channel 0 is the first channel, Hard Disk 0 is the

first hard disk, etc.

Set Up All Cards In ECU or BIOS Setup Utility

SCO UNIX likes to have all cards and disk drives configured in CMOS to work properly.

SCO can actually read the system configuration information. This means that before you

try to configure SCO to use a particular adapter card in the system go in and make sure

that it is set up in the ECU or BIOS setup utility. Even if it is an ISA adapter without a

config file go into the ECU and add a "Generic ISA Adapter" and assign the appropriate

resources such as DMA, Memory, and IRQ to match the settings of the card. (There is a

config file for a Generic ISA Adapter on the NS#2 diskette or Navigator CD-ROM. Add

it as a non-HP board).

Installation To Disk Arrays

Installation to a logical drive, on a disk array, larger than 2048 MB is not recommended.

For SCO versions 5.0.x, larger drives are possible but for backwards compatibility and

ease of system administration logical drives smaller than 2 GB are recommended for your

root drive. Utility Partition Access Disabled

During SCO UNIX installation, access to the Utility Partition built by the Configuration

Assistant is disabled. Select "Skip" if Configuration Assistant asks you to build the

Utility Partition.

Installation Media

The following installation media is required in addition to the main product CD-ROM or

tape to install SCO UNIX.

For UNIX 3.2.4.2: N1, N2, and M1 diskettes, and the HP Drivers Diskette.

For ODT 3.0 and OpenServer 3.0: N1, N2, and the Release Supplement diskettes, and the

HP Drivers Diskette.

For MPX 3.0: MPX 3.0.0j, APIC 1.1 from the AHS 3.4.0 distribution, and SLS

UOD393E (or later) "Performance Supplement" diskettes. You may also want to use

SLS UOD421A (or later) to get the latest APIC driver which supports MPS Specification

1.4.

For OpenServer 5.0: The Boot Disk, the Release Supplement 5.0.0d (or later) diskettes,

and the AHS 5.2.0 (or later) BTLD for the latest arad and alad SCSI drivers, and the HP

Drivers Diskette.

For OpenServer 5.0.2: The Boot Disk, and the AHS 5.2.0 (or later) BTLD for the latest

arad and alad SCSI drivers, and the HP Drivers Diskette.

For OpenServer 5.0.4: The Boot Disk, the Release Supplement 5.0.4c, and the HP

Drivers Diskette.

For OpenServer 5.0.5: The Bootable CD-ROM, the Release Supplement 5.0.5a, and the

HP Drivers Diskette.

For OperServer 5.0.6: The Bootable CD-ROM and the HP drivers Diskette.

Swap Space

You may wish to increase the swap space from the default provided. UNIX uses the

swap space to swap the least-recently used pages in and out of memory. If you have the

disk space available, you might consider using the default, or doubling the size of the

physical memory, whichever is greater.

Additional File Systems

Selecting "/u file system", or some other file system in Release 5.0.x, sets up a separate

file system in addition to the root file system. If you select an additional file system, you

will then be asked to allocate disk space between your root and your additional file

system.

Be sure to leave enough space in your root file system for installing future applications.

Remember that any application files that you place in your /u file system reduce the space

left for user data files.

A scratch division is an area that FSCK (file system check) uses to record data in case of

a problem. It is probably safer to accept a scratch division, so that FSCK can function

properly if you ever need it.

Configuring a Mouse

All HP NetServers have a PS/2 style mouse. This is also know as a mini-DIN or

keyboard mouse. If you want to configure such a mouse as part of the operating system

installation, choosing "Low resolution Keyboard mouse" is the safest choice for

specifying mouse type. If this is not correct, it can always be changed after the system is

up and running.

Configuring Video for UNIX

When configuring the video for UNIX, standard VGA is the safest choice. You can enter

the correct video driver after the system is up and running. The following video chips are

used in the HP NetServers:

E 30: S3 Trio 64V+, 1MB or 2MB video memory

E 40, LC II, LC 3, LH 3, LH 4, LPr, LXr 8000: Cirrus Logic CL-GD5446, 1MB or 2MB

video memory

E 45, E 50: Cirrus Logic CL-GD5446, 2MB video memory

E 60: ATI Rage IIc AGP video card, 4MB video memory

LC Plus, LD Pro, LH, LH Plus, LH Pro and LH II: Trident TVGA9000I, 512KB video

memory

LS, LX Pro, LXe Pro, LXr Pro: Cirrus Logic CL-GD5424, 512KB or 1MB video

memory

LC 2000, LH 3000 LH 6000, LT 6000r: ATI Rage II c on board card, 2MB video

memory

E 800: ATI Rage XL on board card, 4MB video. Driver and install guide can be copied

from Navigator CD SCO Driver diskette

The wrong video driver can produce blank or unreadable screen displays at the higher

(greater than 640 x 480 VGA) resolutions.

BTLD Tips

The HP NetServers use the BTLD for the internal SCSI controllers. The BTLD is a

driver that can be link-edited into the UNIX system kernel during the booting process.

The link-editing is done by boot (HW) after the driver is loaded into memory, but before

the kernel is started. The HP NetServer Manager CD creates a diskette containing the

SCO UNIX BTLDs.

For the UNIX 3.2v4.2 and 3.0 products, you need an HP disk controller driver diskette

that is created by the HP NetServer Navigator CD. This diskette contains the alad, arad,

amird, and mdac drivers.

For OpenServer 5.0.x, the SCSI controller drivers are built into the SCO product. HP

recommends that you use the latest arad and alad drivers that SCO ships. These drivers

are available from SCO on their AHS 5.2.0 (or later) BTLD disk. HP only ships the

drivers for the HP Disk Array Controller (mdac), the HP NetRAID Controller (amird),

the Adaptec alad driver (use alad325 on the link line), the Adaptec blad driver for SCSI

Ultra 2 (use blad325 on the link line) and the Symbios slha driver (use symha on the link

line), but not the Adaptec arad driver, on the driver diskettes that are created by the HP

NetServer Navigator CD.

Driver Names for HP-Supplied Controllers

The following table lists the names of required drivers for the HP-supplied controllers.

NOTE: HP currently does not support ultra SCSI mode on the AIC7880

controllers when they are connected to the HP Storage System 6. Ultra SCSI

mode is supported for disks installed in the HP NetServer cabinet and in the HP

NetServer Rack Storage System 8 and 12.

Troubleshooting

SCO OpenServer is very specific about the hardware configuration it expects when

installing. The following limitations apply:

The root hard disk and the install device should both be on the primary SCSI channel.

The root hard disk must be SCSI ID 0. The first SCSI tape drive must be SCSI ID 2.

The first SCSI CD-ROM drive must be SCSI ID 5, or for an IDE CD-ROM use the

CD-ROM as the master device.

The correct SCSI ID is especially important if you are installing from the tape or CD-

ROM drive. If you have a complicated hardware configuration, install SCO

OpenServer using only the minimum system required to install. All additional

hardware can be added afterwards.

N1 and N2 Diskettes

SCO OpenServer comes on floppies, QIC525 tape, or CD-ROM. All versions prior to

OpenServer 5.0.5 require booting the system off the N1 Installation diskette, and perhaps

using the N2 diskette, to build a rudimentary UNIX system as part of the installation

process. OpenServer 5.0.5 has a bootable CD-ROM for installation.

Any error that occurs when you first boot off the N1 diskette is a hardware problem.

Either some piece of hardware is bad or there is a serious hardware configuration error.

Fix this problem before trying to install SCO OpenServer.

When booting off the N1 diskette, always use the link command to link the appropriate

SCSI driver into the system (alad for the E 30, E 40, E 45, E 50, E 60, LC II, LC 3, LD,

LH, LS, or LX; symha for the LH 3, LH 4, LPr, LXr 8000, or LXr 8500). Refer to the

SCO Installation Manual for how to use the link command and the SCO OpenServer

drivers disk for the various NetServers. This driver is not permanently linked into the

kernel until the end of the SCO OpenServer installation.

Most installation errors will occur after inserting the N2 diskette.

Common Errors

The following is a list of error messages and solutions.

WARNING: HD: NO ROOT DISK CONTROLLER

This usually indicates that the NetServer SCSI driver (e.g. alad) was not linked into the

system. One way this can happen is when the installation reaches the point where you

have the following choices:

1. Continue with Installation

2. Install additional packages and you chose 1.

This is the wrong choice when you are adding a BTLD driver such as alad to the

system. You must choose 2 to complete the installation of the alad driver. This may

also happen if the root hard drive is not on the primary SCSI channel.

ALAD: ADAPTER 0 ERROR: SELECTION TIMEOUT

This error could occur if the root hard disk SCSI ID is some value other than 0. The boot

HD must be SCSI ID 0. This could also occur if the hard disk is on the wrong channel in

systems that have the dual channel SCSI.

ALAD: ADAPTER 0 ERROR: SELECTION TIMEOUT: COULDNOT EXTRACT

FILES FROM /DEV/...

The ... in the error message indicates that device that you are using to install SCO

OpenServer. For example, it will be: /dev/Stp0 if you are installing from the QIC525

tape. This message says that SCO OpenServer could not access the device. Check that

the device is working. Check that the SCSI ID is correct. Using any SCSI ID other than

the ones previously listed will not work.

The System Hangs without any Error Messages

This is probably a SCSI bus problem. Check the SCSI setup for errors. Make sure all the

SCSI devices are seen on boot up. One symptom of a SCSI bus termination error is that

some devices are not seen on boot up. Check for bad SCSI devices, bad SCSI

connectors, bad termination, duplicate SCSI IDs.

Serialization Fails

Once you have verified that you have entered the correct serial number/activation key,

check the permissions on the /tmp directory (l -d/tmp). The /tmp directory should have

the following permissions: drwxrwxrwt.

If the permissions differ, enter the following command: chmod 1777 /tmp.

Section 2. Installation Guide

Large Memory Access

SCO UNIX 3.2v4.2, Open DeskTop 3.0, OpenServer 3.0, and MPX 3.0 are limited to 512

MB of physical memory (RAM). The system will ignore any memory above 512 MB.

SCO OpenServer 5.0.0 and 5.0.2 can access 512 MB of physical memory (RAM) without

any patches. The systems can access up to 4 GB of memory by installing the SCO Large

Server Supplement. OpenServer 5.0.0 requires Large Server Supplement version 1.0.0.

OpenServer 5.0.2 requires Large Server Supplement version 1.1.0. OpenServer 5.0.4,

and later, supports 4 GB of memory without requiring patches.

When installing OpenServer 5.0.0 or 5.0.2 on systems with more than 2048 MB (2 GB)

of memory you will need to limit the memory search during the installation process. To

limit the search add the following string to the boot line you use to start the system

installation:

mem=1m-1024m

After the system is installed you can set the correct memory size in the file

“/etc/default/boot”. See the man page for “boot” for the syntax of this file.

There is a defect in OpenServer 5.0.0 and 5.0.2 that causes the system to report a negative

memory size on systems with more than 2 GB of memory. This defect does not appear to

cause operational problems but it may cause problems for shell scripts that use the

“memsize” command.

SCSI Extended Translation Setting

The SCSI extended translation setting for disks with a capacity larger than 1 GB should

be set to ‘disabled’ for all versions of SCO UNIX, Open DeskTop, and OpenServer 3.0.

For OpenServer 5.0.x you can use SCSI extended translation. (Run the EISA

Configuration Utility, or the AIC SCSI BIOS utility <Ctrl>-A, or <Ctrl>-C for Symbios

BIOS utility to set this parameter.)

MPS Table Setting On NetServer LS and LX for SCO MPX

For the HP NetServer LS and LX with multiprocessors, you must set the MPS

configuration parameter to the correct MPS Table setting.

1. Run the EISA Configuration Utility.

2. Move to the MPS Table selection.

3. Select the MPS table value 1.1 for SCO MPX 3.0. You may use MPS table value 1.4

if you install SCO patch /SLS/uod421a (available on SCO's FTP site).

Select MPS table value 1.4 for SCO OpenServer 5.0.x.

Logical Disk Size for the HP Disk Array Controller and the HP

NetRAID Adapter

During system configuration, the DAC configuration utility on the HP NetServer

Navigator CD-ROM helps you set logical disk size in the disk array configuration

process. If the boot drive is on the disk array controller, set the logical disk size to 2048

MB or less.

HP Disk Array Controller Logical Disk Addressing

The logical disks configured on the HP Disk Array controller are all addressed as LUN

(logical unit number) 1. The individual logical disks are addressed through the SCSI ID

field in the SCO "mkdev" command. For example, the first logical disk is SCSI ID 0,

LUN 1 and the second logical disk is SCSI ID 1, LUN 1.

HP NetRAID Controller Logical Disk Addressing

The logical disks configured on the HP NetRAID controller are all addressed as SCSI ID

0. The individual logical disks are addressed through the LUN (logical unit number)

field in the SCO "mkdev" command. For example, the first logical disk is SCSI ID 0,

LUN 0 and the second logical disk is SCSI ID 0, LUN 1.

HP NetRAID Controller Utilities

Two utility programs are installed on the system when the HP NetRAID driver is

installed. The first utility is the HP NetRAID controller monitor program "amirdmon".

Amirdmon is started when the system enters multi-user mode. The second utility is the

controller configuration program "megamgr". Megamgr can be run when the system

administrator needs to reconfigure the HP NetRAID controller.
