This section describes how to install and configure the Dell small
computer system interface (SCSI) device drivers included with your Dell PowerEdge 2300
computer system. These device drivers are designed to work with the Adaptec AIC-7890 LVD
Ultra2 Wide SCSI-3 controller and the Adaptec AIC-7860 Ultra/Narrow SCSI-3 controller on
the system board.
The AIC-7890 supports up to six
internal SCSI hard-disk drives via a standard SCSI backplane board, while the AIC-7860
supports up to three externally accessible SCSI devices in the system's external drive
bays.
The AIC-7890, AIC-7860, and the
optional AHA-2940U2W SCSI controller card are all part of the Adaptec 78xx series of SCSI
controllers, and all use the 78xx series of SCSI device drivers provided by Dell. The
Adaptec SCSI basic input/output system (BIOS), which is stored in your computer system's
flash memory or on the optional AHA-2940U2W SCSI controller card, links these SCSI device
drivers to the AIC-7890 and AIC-7860 SCSI controller chips or the optional AHA-2940U2W
SCSI controller card.
If you are using an optional Dell
PowerEdge Expandable RAID Controllers, refer to the next section, "Installing SCSI
Drivers for a Dell PowerEdge Expandable RAID Controller in Windows NT 4.0," or to
your Dell PowerEdge Expandable RAID Controller documentation for information on installing
your SCSI device drivers.
For instructions on installing SCSI
hardware devices such as hard-disk drives, tape drives, or CD-ROM drives, trained service
technicians should see Chapter 9, "Installing Drives in the External Bays," and
Chapter 10, "Installing Drives in the Internal Bays," in your Installation
and Troubleshooting Guide. After the SCSI devices you plan to use are installed, you
may need to install and configure one or more SCSI device drivers so that your SCSI
devices can communicate with your operating system.
SCSI device drivers are provided for
the following operating systems:
- Microsoft Windows NT Server 4.0
- Novell NetWare 4.11
See "Using
the Dell Server Assistant CD," for instructions on creating a diskette of
drivers for your operating system. For instructions on configuring the SCSI device
drivers, see the appropriate sections in this chapter.
To install SCSI drivers for a PowerEdge
Expandable RAID Controller in Win-
dows NT 4.0, follow these steps:
1. Boot from the Microsoft Windows NT
Server CD, and press <F6> when the first Windows NT Setup screen appears.
This disables automatic detection of
SCSI devices.
2. Load the PowerEdge RAID II NT
driver.
Press <s> for the Specify
Additional Device option. Insert the PowerEdge Expandable RAID Controller driver diskette
into drive A, and select PowerEdge RAID II NT DRIVER from the list of drivers.
3. Press <Enter> and continue
with the setup.
The screen should list the following
SCSI device drivers:
Adaptec AHA-294X/AHA-394X/AIC-87XX SCSI
Controller
PowerEdge RAID II NT DRIVER
The readme.txt files that
are included with your SCSI device drivers (in the device driver subdirectories in the
\pe2300\scsi subdirectory on the CD) provide updates to the information in this chapter.
Use the editor included with your
operating system to view or print the readme.txt file or any other readme
file.
The BIOS for the built-in Adaptec
AIC-7890 and AIC-7860 SCSI controllers includes the menu-driven SCSISelect configuration
utility, which allows you to change SCSI controller settings without opening the computer.
SCSISelect also contains SCSI disk utilities that let you low-level format or verify the
disk media of your SCSI hard-disk drives.
SCSI Select Default Settings
Default settings for the optional
Adaptec AHA-2940U2W SCSI controller and the built-in AIC-7890 and AIC-7860 SCSI
controllers are shown in Table 1. These default settings are
appropriate for most Peripheral Component Interconnect (PCI) systems. Run SCSISelect only
if you need to change any of the default settings.
 |
NOTE: The SCSISelect Utility must be run for both
the AIC-7890 and AIC-7860 SCSI controllers if you need to change the configuration
settings.
|
The term host adapter is used
throughout this chapter to refer to the built-in AIC-7890 and AIC-7860 SCSI controllers or
the optional AHA-2940U2W SCSI controller card.
For situations in which you might want
or need to change the settings, see the descriptions of each setting in the following
subsections. To change any of the default settings or to format or verify a disk, see
"Starting the SCSISelect Utility" found later in this chapter.

The basic host adapter settings are the
SCSISelect settings most likely to require modification:
- Host Adapter SCSI ID -- This option sets the host adapter's SCSI
identification (ID). The default setting is SCSI ID 7, which allows the host adapter to
support narrow SCSI devices in addition to wide SCSI devices. Dell recommends that you
leave the host adapter set to SCSI ID 7.
- SCSI Parity Checking -- This option determines whether the host
adapter verifies the accuracy of data transfer on the SCSI bus. The default setting is
Enabled. You should disable SCSI Parity Checking if any SCSI device connected to the host
adapter does not support SCSI parity; otherwise, leave it enabled. Most SCSI devices
support SCSI parity. If you are unsure if a device supports SCSI parity, consult the
documentation for the device.
- Host Adapter SCSI Termination -- This option sets termination on the
host adapter. The default setting for the Adaptec AIC-7860 host adapters is Enabled; the
default setting for the AIC-7890 host adapter is Automatic. Dell recommends that you leave
this option set to the default.
The boot device settings allow you to
specify the device from which to boot your computer:
- Boot Target ID -- This option specifies the SCSI ID of the device
from which you wish to boot your system. SCSI IDs are set for the hard-disk drive
according to the drive's location on the backplane board (see Figure
2 for the SCSI ID of each drive location). The default setting for Boot Target ID is
SCSI ID 0.
- Boot LUN Number -- If your boot device has multiple logical unit
numbers (LUNs) and Multiple LUN Support is enabled (see "Advanced Host Adapter
Settings" found later in this section), this option allows you to specify a
particular LUN from which to boot on your boot device. The default setting is LUN 0.
The SCSI device/configuration settings
allow you to configure certain parameters for each device on the SCSI bus. To configure a
specific device, you must know the SCSI ID assigned to that device. If you are not sure of
the SCSI ID, see "Using the SCSI Disk Utilities" found later in this section.
- Initiate Sync Negotiation -- This option determines whether the host
adapter initiates synchronous data transfer negotiation (sync negotiation) between itself
and the device. The default setting is Yes.
Synchronous data transfer negotiation
is a SCSI feature that allows the host adapter and its attached SCSI devices to transfer
data in synchronous mode. Synchronous data transfer is faster than asynchronous data
transfer.
The host adapter always responds to
sync negotiation if the SCSI device initiates it. If neither the host adapter nor the SCSI
device initiates sync negotiation, data is transferred asynchronously.
Normally, you should leave the Initiate
Sync Negotiation setting enabled, because most SCSI devices support synchronous
negotiation and because it allows for faster data transfer.
|
NOTE: Some older SCSI-1 devices do not
support sync negotiation. This may cause your computer to operate erratically or hang if
Initiate Sync Negotiation is set to Yes. Set Initiate Sync Negotiation to No for these
devices. |
- Maximum Sync Transfer Rate -- This option sets the maximum
synchronous data transfer rate that the host adapter supports. The host adapter supports
rates up to 80 megabytes per second (MB/sec). The default setting is 80 MB/sec (the
maximum).
If the host adapter is set to not
negotiate for synchronous data transfer, the maximum synchronous transfer rate is the
maximum rate that the host adapter accepts from the device during negotiation. (This is
standard SCSI protocol.)
- Enable Disconnection -- This option (sometimes called
disconnect/reconnect) determines whether the host adapter allows the SCSI device to
disconnect from the SCSI bus. Enabling disconnection allows the host adapter to perform
other operations on the SCSI bus while the SCSI device is temporarily disconnected. The
default setting is Yes.
Leave Enable Disconnection set to Yes
if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus
performance. If only one SCSI device is connected to the host adapter, set Enable
Disconnection to No to achieve slightly better performance.
- Initiate Wide Negotiation -- This option determines whether the host
adapter attempts 16-bit data transfer instead of 8-bit data transfer. The default setting
is Yes.
|
NOTE: Some 8-bit SCSI devices may have
trouble handling wide negotiation, which may result in erratic behavior or a hang
condition. For these devices, set Initiate Wide Negotiation to No. |
When this option is set to Yes, the
host adapter attempts 16-bit transfer. When this option is set to No, 8-bit data transfer
is used unless the SCSI device itself requests wide negotiation. The effective transfer
rate is doubled when 16-bit data transfer is used because the data path for wide SCSI is
twice the size of normal 8-bit SCSI.
- Send Start Unit Command -- This option determines whether the start
unit command is sent to the SCSI device during the boot routine. The default setting is
Yes.
Setting this option to Yes reduces the
load on your computer's power supply by allowing the host adapter to start SCSI devices
one at a time when you boot your computer. When this option is set to No, the devices are
allowed to start at the same time. Most devices require you to set a jumper before they
can respond to this command.
|
NOTE: For many devices, if Send Start
Unit Command is set to Yes, the boot routine time will vary depending on how long it takes
each drive to start. |
- BIOS Multiple LUN Support -- This option provides support for
peripherals that contain multiple SCSI devices, such as autoloading tape drives and CD-ROM
changers.
- Include in BIOS Scan -- This option enables you to set whether the
system BIOS scans this device during system startup. The default setting is Yes.
The advanced host adapter settings
should not be changed unless absolutely necessary. These values are set by Dell, and
changing them may cause conflicts with the SCSI devices.
- Host Adapter BIOS -- This option enables or disables the host adapter
BIOS. The default setting is Enabled.
NOTE: Several SCSISelect options are not valid unless the host
adapter BIOS is enabled.
If you are booting from a SCSI
hard-disk drive connected to the host adapter, the BIOS must be enabled. You should
disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM
drives) are all controlled by device drivers and do not need the BIOS.
- Support Removable Disks Under BIOS As Fixed Disks -- This option
controls which removable-media drives are supported by the host adapter BIOS. The default
setting is Boot Only. The following choices are available.
 |
CAUTION: If a
removable-media SCSI device is controlled by the host adapter BIOS, do not remove the
media while the drive is on or you may lose data. If you want to be able to remove media
while the drive is on, install your removable-media device driver and set this option to
Disabled. |
- Boot Only. Only the removable-media drive designated as the boot
device is treated as a hard-disk drive.
- All Disks. All removable-media drives supported by the BIOS are
treated as hard-disk drives.
- Disabled. No removable-media drives are treated as hard-disk drives.
In this situation, software drivers are needed because the drives are not controlled by
the BIOS.
- Plug and Play SCAM Support -- This option provides automatic
configuration of SCSI devices in operating systems that support Plug and Play. Dell
recommends that you leave this option set to Disabled.
- Reset SCSI Bus at IC Initialization -- This option enables the SCSI
bus to be reset when the controller is initialized. The default setting is Enabled.
- Extended BIOS Translation For DOS Drives > 1 GB -- This
option determines whether extended translation is available for SCSI hard-disk drives with
capacities greater than 1 gigabyte (GB). The default setting is Enabled.
|
CAUTION: Back up your hard-disk drive before you change the
translation scheme. All data is erased when you change from one translation scheme to
another. |
The standard translation scheme for
SCSI host adapters provides a maximum accessible capacity of 1 GB. To support hard-disk
drives larger than 1 GB, the 78xx series host adapters include an extended translation
scheme that supports hard-disk drives as large as 8 GB, with a maximum partition size
of 2 GB under the MS-DOS operating system.
Extended BIOS translation is used only
with MS-DOS 5.0 or later. It is not necessary to enable this setting if you are using
another operating system such as Novell NetWare.
When you partition a hard-disk drive
larger than 1 GB, use the MS-DOS fdisk utility as you normally would. Because the
cylinder size increases to 8 MB under extended translation, the partition size you choose
must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk
rounds up to the nearest whole multiple of 8 MB.
- Display <Ctrl><a> Message During BIOS Initialization --
This option determines whether the Press <CTRL><A> for SCSISelect (TM)
Utility! message appears on your screen during system start-up. The default setting is
Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing
<Ctrl><a> after the host adapter BIOS banner appears.
- Multiple LUN Support -- This option determines whether your system
supports booting from a SCSI device that has multiple LUNs. The default setting is
Disabled. Enable this option if your boot device has multiple LUNs.
- BIOS Support For Bootable CD-ROM -- This option determines whether
the host adapter BIOS provides support for booting from a CD-ROM drive. The default
setting is Enabled.
- BIOS Support For Int 13 Extensions -- This option determines whether
the host adapter BIOS supports disks with more than 1024 cylinders. The default setting is
Enabled.
- Support For Ultra SCSI Speed -- This option determines whether the
host adapter supports the fast transfer rates (20-40 megabytes per second
[Mbps]). The default setting is Enabled.
You can start the SCSISelect utility by
pressing <Ctrl><a> when the following prompt appears briefly during start-up:
Press <CTRL><A> for SCSISelect (TM) Utility!
The first menu displays the
Configure/View Host Adapter Settings and SCSI Disk Utilities options.
SCSISelect uses menus to list options
you can select. To select an option, use the up- and down-arrow keys to move the cursor to
the option; then press <Enter>.
In some cases, selecting an option
displays another menu. You can return to the previous menu at any time by pressing
<Esc>. To restore the original SCSISelect default values, press <F6>.
To access the SCSI disk utilities,
select the SCSI Disk Utilities option from the menu that appears when you start
SCSISelect. When the option is selected, SCSISelect immediately scans the SCSI bus (to
determine the devices installed) and displays a list of all SCSI IDs and the device
assigned to each ID.
When you select a specific ID and
device, a small menu appears, displaying the Format Disk and Verify Disk Media options.
- Format Disk -- This option runs a
utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI disk
drives are formatted at the factory and do not need to be formatted again. The Adaptec
Format Disk utility is compatible with the vast majority of SCSI disk drives.
CAUTION: The Format Disk option destroys all
data on the hard-disk drive.
- Verify Disk Media -- This option runs a utility that allows you to
scan the media of a hard-disk drive for defects. If the utility finds bad blocks on the
media, it prompts you to reassign them; if you select Yes, those blocks are no longer
used. You can press <Esc> at any time to exit the utility.
To exit SCSISelect, press <Esc>
until a message prompts you to exit. (If you changed any 78xx series host adapter
settings, you are prompted to save the changes before you exit.) At the prompt, select Yes
to exit, and then press any key to reboot the computer. Any changes you made in SCSISelect
take effect after the computer boots. (You can select No at the prompt if you are not
ready to exit SCSISelect.)
This section provides the following
information about installing the Dell SCSI drivers for the Microsoft Windows NT 4.0
operating system:
- Installing and/or updating the SCSI drivers for Windows NT
- Removing a host adapter
- Swapping a host adapter
- Restoring a configuration if Windows NT fails to boot
This section provides the information
needed to install and use the Dell SCSI drivers for the 78xx series of SCSI controllers
with Windows NT.
The Windows NT 4.0 driver diskette you
create for the Microsoft Windows NT Server operating system contains the files needed for
driver installation. The scsi subdirectory on the diskette contains the following files
to be used with Windows NT:
- aic78xx.sys -- Adaptec's 78xx series driver for Windows
NT
- oemsetup.inf -- A file used by Windows NT Setup for
driver installation
- readme.txt -- A text file describing the Adaptec 78xx
driver for Windows NT
If you are installing Windows NT for
the first time, see the following subsection, "Installing Windows NT and the
Driver," to begin driver installation. If Windows NT is already installed in your
system, see "Using Windows NT to Install or Update the Driver" found later in
this section.
Windows NT 4.0 has SCSI drivers for the
Adaptec 78xx series of SCSI controllers integrated into the operating system. When you
load the operating system software, the drivers are automatically loaded. However, Dell
recommends that you update the aic78xx.sys driver using the diskette of
drivers that you created from the Dell Server Assistant CD. To install or update
the aic78xx.sys driver for Windows NT 4.0, see the next subsection.
This section describes how to install
or update the aic78xx.sys driver if Windows NT is already installed. If you
are installing Windows NT for the first time, see the previous subsection,
"Installing Windows NT and the Driver."
Follow these instructions only if
Windows NT 4.0 is already installed:
1. Click the Start button, point to
Settings, and click Control Panel.
2. Double-click the SCSI Adapters icon.
3. Click the Driver tab and then click
Add.
4. Click Have Disk.
5. Insert the Windows NT 4.0 driver
diskette you created into drive A.
6. In the Copy Manufacturer's Files
From: field, type a:\scsi\ and click OK.
7. Select Adaptec
AHA-294x/AHA-394x/AHA4944 or 78xx PCI SCSI Controller (NT 4.0). Then click OK.
8. If the following message appears,
click New to replace the existing driver:
The driver(s) for this SCSI Adapter are
already on the system. Do you want to use the currently installed driver(s) or install new
one(s).
9. If the following message appears,
type a:\scsi\ in the dialog box and click Continue:
Please enter the full path to Adaptec's
installation files.
These files are located in \SCSI on the
Dell Windows NT 4.0 Driver diskette.
The driver is copied from the diskette
to your system.
10. Click Yes when prompted to restart
the system, and remove the diskette from drive A.
After the system reboots, the new
driver is active. Some drive letter assignments may have changed from the previous
configuration.
Removing a PCI expansion-card SCSI
controller is as simple as physically removing it from its slot when your computer is shut
down. Windows NT boots and functions properly in this configuration, but a warning message
is generated every time you boot Windows NT.
|
CAUTION: If you have
removed a host adapter but still have other host adapters of the same type installed in
your computer, do not use Windows NT Setup to remove the device driver. |
To eliminate the warning message, you
must update the Windows NT software configuration as follows:
1. Select and start the Windows NT
Setup program.
There is a brief pause while Windows NT
Setup scans your hardware configuration.
2. Select the Options pull-down menu,
and then select Add/Remove SCSI Adapters.
The SCSI Adapter setup program displays
a list of all host adapters currently installed.
3. Select the host adapter you want to
remove, and click Remove. When the Windows NT Setup program asks you for confirmation,
click OK.
Because SCSI device drivers are loaded
during system bootup and because they may be needed to load Windows NT itself, a message
may appear warning you that Windows NT may not start if you remove the SCSI adapter.
4. When you are sure you are removing
the correct host adapter type, click OK.
5. Return to step 3 if you want to
remove driver support for other types of host adapters, or click Close to exit the SCSI
adapters portion of Windows NT Setup.
6. Close the Windows NT Setup program.
When the following message appears, click OK to exit:
The changes you have made will not take
effect until the computer is restarted.
If this message does not appear, no
changes have been made to the Win-
dows NT system configuration.
7. Restart your computer.
|
NOTE: The Windows NT Setup program does
not delete the device driver from your hard-disk drive; it only updates Windows NT
software configuration information so that the device driver is no longer loaded during
system start-up. |
The procedure for swapping one type of
host adapter for another is similar to the procedure for adding a host adapter, except
that you make all software configuration changes while Windows NT is running--before you
make the hardware changes.
1. Install the driver for the new host
adapter by following the steps in "Installing or Updating the Driver With Windows NT
4.0" found earlier in this section.
It is not essential to remove the
device driver for the host adapter you are replacing. Windows NT dynamically detects the
absence or presence of host adapter hardware, and no problems should arise if you leave
the existing device driver installed. You can remove the device driver later, after you
have successfully rebooted Windows NT. However, if you leave the driver in, the system
alerts you with an error message about the extra device driver every time you boot. See
the previous subsection, "Removing a Host Adapter."
2. After the new device driver is
installed, shut down Windows NT and replace the existing host adapter.
3. Restart your computer and Windows
NT.
Some drive letter assignments may have
changed from the previous configuration.
The boot manager for Windows NT
contains recovery logic to allow you to return to the last known good configuration. If
you have changed your host adapter configuration and Windows NT no longer boots, follow
these steps to recover:
1. Undo any hardware changes you have
made to the computer since it was last operational.
2. Reboot the computer. Watch the
display carefully during start-up. If the following message appears, press the spacebar
key, press <l> at the next screen, and then follow the instructions on the screen to
continue booting with the last known good configuration:
Press spacebar NOW to invoke the Last
Known Good menu
3. When your computer is operational
again, check all of the hardware and software configuration changes you want to make. Look
specifically for conflicts with parts of the existing system configuration that are not
being changed.
If you cannot determine the source of
the error, contact Dell for assistance. See Chapter 11, "Getting Help," in the Installation
and Troubleshooting Guide for instructions on contacting Dell for technical
assistance.
This section provides the following
information about installing the Dell SCSI drivers for NetWare 4.11:
- Installing the EZ-SCSI utility
- Installing and/or updating the Dell SCSI driver for NetWare 4.11
- Automatic driver loading using startup.ncf and autoexec.ncf
- Booting a NetWare server from a SCSI drive, formatting media, and
using removable media
- Troubleshooting error messages generated during initialization
This
subsection provides the information needed to install and use the Dell SCSI drivers for
Novell NetWare 4.11. The Dell SCSI drivers for NetWare support the optional Adaptec
AHA-2940U2W and all Adaptec 78xx series SCSI controllers.
Before you begin installation of the
SCSI drivers for NetWare, you must create a diskette of drivers for NetWare 4.11 and a
diskette that contains the Adaptec EZ-SCSI utility. "Using the Dell
Server Assistant CD," provides instructions for creating these diskettes.
The Dell SCSI drivers for NetWare are
fully tested and approved for NetWare. The NetWare scsi subdirectory on the NetWare 4.11
drivers diskette you create contains files to be used with NetWare 4.11. The following
files appear in the scsi subdirectory on the NetWare driver diskette:
- readme.txt -- An American Standard Code for Information
Interchange (ASCII) text file describing Adaptec's drivers for NetWare.
- aic78u2.ham -- NetWare driver for Adaptec's 7890
and AHA-2940U2W Ultra2 SCSI series host adapters.
- aha2940.ham -- NetWare driver for Adaptec's 7860 and
AHA-2940UW SCSI host adapters.
- aspitran.dsk -- Adaptec's ASPI ® transport
layer driver for NetWare.
- aspicd.dsk -- Adaptec's device driver for a CD-ROM
drive.
- nbi.nlm -- File required by the NetWare bus
interface.
- nwpa.nlm -- File required by the NetWare bus
interface.
- nwpaload.nlm -- File required by the NetWare bus
interface.
- cdrom.nlm -- File required by the NetWare bus
interface.
- aic78u2.ddi -- A driver definition information file
for the 78xx Ultra2 SCSI series host adapters that provides setup information to NetWare
during installation; NetWare then prompts you with parameters to be configured for the
device driver during the installation process.
- aha2940.ddi -- A driver definition information file
for the AHA-2940U2W host adapter
- aspicd.ddi -- A device driver definition file.
- aspitran.ddi -- A device driver definition file.
To begin driver installation, first
load the EZ-SCSI utility as described in the following subsection, "Installing
EZ-SCSI." Then see "Installing NetWare 4.11" found later in this section to
install NetWare 4.11 for the first time.
|
NOTE: Your system must have a bootable
version of MS-DOS installed before you can complete the Novell NetWare installation. |
The Adaptec EZ-SCSI utility is an
MS-DOS application that automatically configures the computer to use an Adaptec SCSI host
adapter and the devices connected to it. The Adaptec EZ-SCSI utility also copies
applications and device drivers to the computer's hard-disk drive. The configuration and
installation process is explained with a series of screens. In most cases, the computer
and SCSI devices are configured to take full advantage of all the performance benefits of
SCSI when you accept the default values suggested by these screens.
Follow these steps to install the
Adaptec EZ-SCSI utility:
1. If you have not already done so,
create an Adaptec EZ-SCSI diskette for the version of NetWare you are using.
"Using the Dell Server Assistant CD,"
provides instructions for creating this diskette.
2. Insert your Adaptec EZ-SCSI diskette
into diskette drive A.
3. Type dosinst and press
<Enter>.
A message appears while the EZ-SCSI
utility loads into memory.
4. When the first EZ-SCSI screen
appears, read the text carefully.
You can press <F1> on any screen
for additional help. (Press <Esc> to exit a Help screen.)
5. Press <Enter> to continue with
the installation.
6. Follow the instructions that appear
on the screen. Press <Enter> at every screen to accept the EZ-SCSI default values.
If you accept all the default values,
the EZ-SCSI utility copies the files from the diskette to the c:\scsi
directory. (The EZ-SCSI utility creates this directory if the directory does not already
exist.) The EZ-SCSI utility also adds command lines to your computer's configuration files
(autoexec.bat and/or config.sys) that will load the
required device drivers into memory when you boot your computer.
7. Press <Esc> to continue after
the EZ-SCSI utility enters changes to your system configuration files.
If you want to copy the files to a
different directory or control the changes to your configuration files, follow the
instructions on the screen. Press <F1> on any screen to see more information.
|
NOTE: If the EZ-SCSI utility is unable
to locate the mscdex.exe file in the c:\dos directory, it will prompt for a pathname to
access this file. (Without this file, the utility cannot access the computer's CD-ROM
drive.) |
8. When the message (Adaptec EZ-SCSI
has been successfully installed...)appears on the screen, press <Enter> or
<Esc> to exit the EZ-SCSI utility, and remove the Adaptec EZ-SCSI diskette from the
drive. Then reboot your computer by pressing <Ctrl><Alt><Del>.
This section describes how to install
the aic78u2.ham and aha2940.ham drivers at the same
time you install NetWare 4.11. If NetWare 4.11 is already installed and you wish to
install or update the aic78u2.ham and aha2940.ham
drivers, refer to the NetWare User's Guide for installation instructions. Also, refer to
the NetWare User's Guide for information about partitioning, creating a server name, and
checking the internetwork packet exchange (IPX) network number.
Follow these steps only if you are
upgrading to NetWare 4.11 or installing it for the first time:
1. Make backup copies of all Novell
diskettes, and use those backup copies as your working diskettes.
2. Boot MS-DOS on your computer.
3. Change to the CD-ROM drive prompt.
The installation files are located in
the root directory on the CD-ROM.
4. Type install and press
<Enter>.
5. Select a language at the language
selection screen and press <Enter>.
6. Select whether you want to perform a

The subsections that follow provide
procedures and tips on the following topics:
- Formatting media
- Using removable media
- Using drives that are tested and approved for NetWare
- Using the NetWare tape backup utility
- Setting Up a CD-ROM drive with NetWare 4.11
NetWare's install.nlm program lets you
optionally format a hard-disk drive for use with NetWare. If you are using SCSI drives,
the program allows you to low-level format several SCSI drives simultaneously. The NetWare
format procedure is not the same as using fdisk or format under MS-DOS.
|
CAUTION: You should not use NetWare to format a hard-disk
drive that contains partitions for other operating systems because that information may be
destroyed. |
|
NOTE: When you select a hard-disk drive to format,
the install.nlm program prompts you to enter an interleave value from 1 to 9. You may also
enter an interleave value of 0 (zero). When formatting SCSI hard-disk drives or removable
drives on the Adaptec 78xx host adapter SCSI bus, Dell recommends that you use an
interleave value of 0. This 0 interleave value instructs the hard-disk drive to use its
optimal interleave value. This option was unavailable in NetWare 3.0.
|
The aic78u2.ham
driver module fully supports removable-media disk drives, including magneto-optical
drives. Removable media is treated as a standard SCSI hard-disk drive, with some
exceptions:
- The driver only recognizes and registers media with 512 bytes/sector.
- NetWare allows you to mount or dismount the media and lock or unlock
the media.
These removable media options are
supported by NetWare's monitor.nlm program.
Follow these steps to set up the
removable media:
1. Load monitor.nlm to display the
various options.
2. Select Disk Information.
All system hard-disk drives appear.
3. Select the removable-media device.
Drive status options appear as shown in
Table 2.

Mounting causes a drive to come online
as a NetWare storage device. Dismounted drives are inactive and cannot be accessed.
Before you eject your current media,
you should first dismount it (using menu option 5). When the mount status is
Dismounted, you can eject the media. However, NetWare does not allow you to dismount media
that are locked.
To insert your new media, wait for the
drive to spin up, and then select the Removable Drive Mount Status option.
If your removable-media device supports
the lock/unlock feature, you can lock the media (using menu option 6). The media must be
in the Not Locked state before you can eject it. If the media is locked, it cannot be
ejected when you press the eject button.
To be fully certified as NetWare
"Yes, Tested and Approved," a drive and host adapter must both pass a
qualification process that takes place before you see the product. The goals of NetWare
testing are to simplify installation and provide the highest quality disk subsystem.
Adaptec 78xx series host adapters and
their drivers are fully tested and approved for NetWare. This means that you can purchase
a NetWare drive (certified as "Yes, Tested and Approved") from a vendor, connect
it to your computer system or host adapter, partition it, and create a volume without any
compatibility concerns.
NOTE: Dell recommends using only Dell-tested drives.
Adaptec's aic78u2.ham
driver module is flexible enough to allow you to connect SCSI drives that are tested and
approved for NetWare as well as standard SCSI drives to a single host adapter. The driver
registers each hard-disk drive accordingly.
Drive registration is a
user-transparent process; no user interaction is required. You can tell that the drive has
been detected as NetWare-tested and NetWare-approved if the message NetWare Yes Tested and
Approved is included in the drive description string that appears when you run monitor.nlm
(disk options).
Included with NetWare is a server-based
tape backup utility called sbackup.nlm. This allows backup of server disk drives to a
server tape drive. The sbackup.nlm utility supports Adaptec host adapters. Use the
following procedure to load the backup utility:
1. Load the SCSI adapter driver.
The syntax to load the aic78u2.ham
driver follows:
load [pathname]\aic78u2.ham
[options] slot=x
The ASPI layer (aspitran.dsk) is
automatically loaded.
2. Refer to the Novell NetWare
documentation for additional instructions on loading the server backup software. Refer to
the NetWare Server Backup User's Guide to load the tsa and sbackup modules.
To use a CD-ROM drive with NetWare
4.11, follow these instructions:
1. Ensure that the CD-ROM driver for
NetWare 4.11 (aha2940.ham) is loaded. If necessary, load the driver by
entering the following command line:
load [pathname]\aha2940.ham
slot=x
2. Load aspicd.dsk by entering the
following command line:
load [pathname]\aspicd.dsk
|
NOTE: If aspicd.dsk does not work, unload it and
load it again. The first load initializes the host adapter; unloading and reloading allows
the initialization to complete.
|
3. Load cdrom.nlm as follows:
load [pathname]\cdrom.nlm
4. Enter the following line at the
prompt, and then note the number and name of the CD that appears:
cd device list
5. Enter the number or volume name of
the CD at the command line:
cd mount [number]
or
cd mount [name]
The CD-ROM is now ready to be accessed
as a volume.
The Adaptec 78xx SCSI bus master
firmware increases the SCSI performance of the Adaptec 78xx series host adapters under
multitasking environments. The firmware uses a paging mechanism to handle up to 255
simultaneous SCSI commands. The sequencer can simultaneously manage up to 32 tagged, or 2
nontagged, SCSI commands for each SCSI device, up to a limit of 255 SCSI commands. The
firmware can queue as many commands as the operating system is able to send to the host
adapter. To set this feature, enter the following command:
max_tags=n
In general, a low number for the
max_tags option gives better sequential performance. This value varies with the level of
random disk accesses and drive characteristics.
NOTE: A large value for max_tags can cause starvation problems
with some drives.
Any error
that occurs while the driver is initializing prevents it from loading. If an error does
occur, the driver causes the computer to beep and then display a numbered error message:
xxx message
The xxx indicates the error code, and
message is a descriptive line describing the error. The error codes are divided into three
categories:
- 000-099 -- Non-host-adapter specific
- 100-299 -- Host-adapter specific
- 300-999 -- Reserved
Specific error codes, such as those in
the following subsections, appear only if you have installed the host adapters and drivers
that generate them.
The following error codes alert you to
error conditions caused by factors not related to the host adapter:
000 Failed ParseDriverParameters call
A call to NetWare's
ParseDriverParameters routine has failed for some unknown reason. The command-line
contains errors, or you pressed <Esc> at the port or slot prompt.
001 Unable to reserve hardware, possible conflict
The driver failed in its attempt to
reserve the host adapter's hardware settings (that is, direct memory access [DMA] and
interrupt request [IRQ] settings). Another card in your system may be causing a conflict
with the host adapter.
002 NetWare rejected card Failed AddDiskSystem call
The driver failed in its attempt to
register the host adapter with NetWare. The file server may not have enough memory.
003 Invalid command line option entered > option
An invalid option was entered on the
command line. The invalid option that was entered is also displayed.
004 Invalid command line, please enter correctly
The driver was unable to understand the
command line options you entered. Be sure you have entered these options correctly.
The following error codes alert you to
error conditions caused by factors related to the host adapter:
200 No host adapter found for this driver to register
No Adaptec 78xx host adapter was found
in your computer for the driver to register. Be sure the host adapter is properly
configured and properly seated in the slot.
203 Invalid `device' setting
You have entered an invalid slot
setting on the command line. You can only enter slot numbers for valid host adapters. If
you load without the slot option, you will be prompted to enter a valid value.
204 Invalid `verbose' setting, use `y'
You can only enter y for this option
(verbose=y).
205 Invalid `removable' setting, use `off'
You can only enter off for this option
(removable=off).
206 Invalid `fixed_disk' setting, use `off'
You can only enter off for this option
(fixed_disk=off).
208 SCSI present but not enabled/configured for PCI
A host adapter is present, but its bus
or device entry has not been enabled.
