1-2 Installing MP-RAS

Completing a Factory Installation

Completing a Factory Installation

If your system was pre-loaded at the factory with NCR UNIX SVR4 MP­RAS, you need to complete the factory installation of the server by
configuring the network.

If you ordered NFS OE (Operating Environment) or C/S OE, STREAMware
TCP for MP-RAS is automatically installed on your server.

Procedure

To complete the software installation, follow these steps:

1. Boot the server. When the UNIX MP-RAS 3.01.01 operating environment
displays, you are asked to configure the network.

2. Answer no to the configuration questions if you do not have the required
information, or type Control+D to exit the configuration screens.

3. Decide if the default pre-installed OE meets your needs. You may need to
re-install the OE if you want to change the file system type for the root file
system or change the system disk layout.

If you want to re-install for these or other reasons refer to the Installing
NCR UNIX SVR4 MP-RAS guide.

If the pre-installed OE is suitable, get the necessary STREAMware
information (contained in the documents listed below), then continue with
Step 4.

– STREAMware TCP for MP-RAS Transition Guide (D1-4790-C)
– STREAMware TCP for MP-RAS Administrator Guide (D1-4788-C)
– STREAMware for MP-RAS TCP User Guide (D1-4787-B)

4. Bring the system to run level 2 (if NFS is running) by typing the
following:

# init 2

5. Configure the network by running the following script:

# /etc/inet/script/tcpconfig.b

NCR S46 Server MP-RAS Support Guide 1-3

Completing a Factory Installation

The symbolic link is /usr/sbin/tcpconfig.

6. Bring the system back to the original run level of

# init original_run_level. For example, init 3.
During the change of the run level, you may be prompted to answer

questions concerning further customization. Questions are based on the
list of packages already installed and on the operating environment (OE)
already loaded.

1-6 Installing MP-RAS

Confirm Hardware Setup

When you set up your hardware, follow these steps:

• Ensure all SCSI devices are not manually set to an ID. SCSI ID’s within

the Hot Dock are dynamically configured by drive location. Ensure drives
are firmly seated in the hot-docking backplane. Drive termination is
provided by the hot-docking backplane.

• Ensure all bus cards are seated properly in the system. For maximum

performance, use EISA or PCI cards, not ISA cards.

• Bootable devices must be attached to either the on-board Adaptec SCSI

channel A or a Mylex DAC960PL adapter in slot 1 of PCI bus 2 (third
slot from the bottom, marked P4).

If a Mylex 960PL adapter is installed in P4, the first bootable system
drive on this controller is considered the boot device if BIOS is enabled.
This interpretation is due to the baseboard device scan order.

Performing a Full Installation

Confirm CMOS Configuration

To use the BIOS setup Utility to confirm the CMOS configuration, follow
these steps:

1. Reboot your system and press F1 when prompted to access the BIOS

Setup.

2. Under Main, verify the following:

– The correct date and time.
– That the Floppy Options parameter is set to “1.44/1.25 MB 3-1/2”

for Floppy A: Type.

3. Under Advanced, Peripheral Configuration Menu, verify the following:
– COM2, 2F8h is enabled if an external UPS is supported with UNIX

MP-RAS.

4. Press F10 to save and exit then press Enter at the Exit Saving Changes
prompt.

NCR S46 Server MP-RAS Support Guide 1-7

Performing a Full Installation

Refer to Chapter 5, “Using the BIOS Setup Utility,” in the NCR S46 Server
User Guide for additional information on CMOS configuration.

Obtain Necessary Media

Before you begin to install MP-RAS, make sure that you have the following
media:

• NCR S-Series Platform CD

• UNIX SVR4 MP-RAS Core CD

• Boot diskette #1 and #2

• License diskette

• Blank 3.5” High Density diskette for creating an emergency repair disk

Configure Disk Arrays Using the Mylex DAC960PL
Adapter

Installing a Mylex DAC960PL Adapter

To prepare the system for Mylex DAC960PL Disk Array Adapter installation,
if not pre-installed at the factory, follow these steps:

CAUTION: Use a grounding strap to prevent harmful static discharge when
handling, installing and cabling host adapters.

CAUTION: A trained service technician should add or remove boards in the
server.

1. Turn off the power to the console and the system. Disconnect the system
power cord from either the rear panel of the system or from the wall
outlet.

2. Refer to the NCR S46 Server Service Guide, Chapter 5, “Servicing
Add-In Boards” for information about inserting and removing add-in
boards.

1-8 Installing MP-RAS

Performing a Full Installation

3. Install the Mylex DAC960PL adapter in Slot 1 of PCI Bus 2 (third PCI

slot from bottom, marked as P4) as instructed in the Mylex DAC960PL

Disk Array Controller User’s Manual and the NCR S46 Server User
Guide. Note that the bottom 4 slots are EISA slots, and the top 6 slots

PCI slots. Even though the Mylex adapter will fit into an EISA slot, the
installer should make sure that it is not installed there; if it is, the adapter
will be damaged.

4. Refer to Chapter 6 “Servicing the SCSI Hot-Docking Backplane” in the

NCR S46 Server Service Guide for cabling your Mylex Disk Array
Adapter in an S46 server. Cabling should be done by a qualified service
technician.

5. Connect the desired disk drives to the Mylex DAC960PL Adapter.

Internal drives are automatically terminated correctly by the Hot-docking
backplane in the S46 server. See the NCR S46 Server User Guide for
more details on the SCSI.

6. Ensure that the CD-ROM and tape drives are connected to the narrow

SCSI cable and to the on-board SCSI Channel A (marked as “SCSI A”).

Configure RAID Disks

To configure RAID Disks, follow these steps:

1. If there are disk drives connected to both the on-board Adaptec controllers

and the Mylex controllers, decide on which disk you want to install the
operating system. Only install the operating system on disk drives
connected to Adaptec controller A (SCSI A) or to the Mylex controller on
PCI BUS 2, Slot 1 (P4).

2. If you want to install the operating system to an array connected to the

Mylex DAC960PL Adapter, ensure the following:

– The Mylex BIOS is “enabled” for the adapter in slot P4.
– The BIOS is “disabled” for all other plug-in SCSI or RAID adapters

in the EISA slots or PCI slots P1 and P2, if any.
The BIOS can remain “enabled” for the on-board Adaptec controllers,

since they are scanned by the BIOS after the Mylex DAC960PL
Adapter in slot P2-1.

NCR S46 Server MP-RAS Support Guide 1-9

Performing a Full Installation

If you want the operating system installed on the Adaptec, ensure the
following:

– The BIOS is “enabled” for the Adaptec controllers.
– The BIOS to “disabled” for all Mylex controllers (using Alt+M) and

any other plug-in SCSI or RAID adapters.

3. Boot to the Diagnostic Partition and run Utilities and Diagnostics.

4. Select “System Config Utils,” “Adapter Config Utils,” then “RAID ­Mylex” and press Enter. Refer to the NCR S46 Server User Guide,

Chapter 6, “Configuring Adapters,” for information about configuring
disk arrays. Also refer to the DAC960PL Disk Array Controller User’s
Guide, if necessary.

5. For best performance, configure the operating system disk(s) as RAID 1
or RAID 6. Other disks should be configured to match the application,
normally as RAID 5. Leave one disk as a hot standby, if desired.

Special Considerations

• If two Mylex Disk Array adapters are used, install the second adapter in
any of the other available PCI slots. Additional Mylex adapters can be
used for external disk expansion cabinets.

• As the system is booting make sure that the Mylex DAC960PL BIOS is
set to DISABLED (using Alt+M) for all additional adapters, except the
adapter in bus 2, slot 1.

• Any external disk expansion cabinet attached to a second Mylex adapter
has proper SCSI terminations at the end of each SCSI bus.

• If the system has disk drives connected to the on-board Adaptec SCSI
controller and to the Mylex DAC960PL-2 controller, the system is
installed either on c100t0d0s0 (Adaptec) or c120t0d0s0 (Mylex),
depending on which one is enabled and scanned first.

• For best performance configure the root and dump disk(s) as RAID 1 or
RAID 6. Other disks should be configured to match the application,
normally as RAID 5. Leave one disk as a hot standby if desired.

1-10 Installing MP-RAS

Performing a Full Installation

• When system reboots after UNIX install, the DAC960PL-2 driver,

“dac960sh” RAID Manager and the “dacmon” monitor have been
installed successfully.

Configure the Server Using the System Configuration
Utility (SCU)

Use the information in this section to configure your server using the SCU.
First consider the information below, then perform the configuration
procedure under “Configuring the Server.”

SCSI Adapters

One Adaptec on-board SCSI controller must be assigned to IRQ 14. The other
controller can be assigned to either IRQ 11 or IRQ 14.

Note: Dissimilar adapter types (SCSI versus Ethernet) should not share the
same IRQ.

Network Adapters

• All PCI Ethernet adapters should be assigned to IRQ 9.
Refer to Chapter 4, “Configuring Your Server” of the NCR S46 Server User

Guide for additional information on the System Configuration Utility.

Configuring the Server

To configure the server using the SCU, follow these steps:

1. At system startup, press D when prompted to boot to the Diagnostic

Partition.

2. At the MS-DOS startup menu press Enter to select “Run Utilities and

Diagnostics (Default - Press “Enter” to Accept).”

3. From the Diagnostic Partition main menu select “System Config Utils,”

select “Execute SCU” and press Enter. When the blue System
Configuration Utility banner page displays, press any key to continue.

NCR S46 Server MP-RAS Support Guide 1-11

Performing a Full Installation

4. From the main SCU menu, highlight “Step 3: Change Configuration
Settings,” and press Enter.

5. Specify an administrative boot/configuration password. If the password
has not been specified, you may press Esc when prompted to bypass this
password, or you may specify a new password and then verify. This
password may be disabled from the System Board setup screen.

Note: Except for EISA and ISA cards, no board names are used, but are
referenced by class name (for example “PCI SCSI Device”), PCI “Bus
number,” and “Dev letter.”

The device scan order, as specified in the NCR S46 Server Users Guide,
Chapter 2, “Getting Started,” can help you determine which specific
vendor card occupies which PCI slot.

“PCI Undefined Device” denotes the INCA (Interrupt and Control ASIC)
chip which arbitrates bus and control handshaking, and can be enabled to
checks such things as internal voltages, temperature, fan failures and
chassis intrusion.

“PCI RAM Device” denotes the Orion Memory Controller (OMC) chip.

6. Highlight “System Board” and press Enter.
– Under “MP Spec Version (Systems Group),” verify that “MP Spec

V1.1” is selected.

– Under “PCI System Error Detection (Management System Group),”

verify that “PCI System Error Detect” is Enabled.

– Under “Secondary IOAPIC Control Option(System Performance),”

verify “Disable Secondary IOAPIC” is listed.

– Under “Shadowing ISA ROMs Options (Memory Subsystem

Group),” verify that all memory regions are “Enabled” except for
regions used as “shared memory” (memory shared between an adapter
and the system, such as on the EiconWAN adapter or the Server
Monitor Module) or regions assigned as memory-mapped I/O. An
adapter’s memory assignments can be viewed from the Global
Resources Map in the SCU.

Note: ROM Shadowing is automatically disabled for an adapter whose .CFG
file contains the string “CACHE=NO” in its memory references.

1-12 Installing MP-RAS

Performing a Full Installation

– Under “Extended Memory Options(Memory Subsystem Group),”

verify that “Cache Mode” is set to “Enable” and that “1MB ISA Hole
Control” is set to “Disable.”

– Set the On-Board Communications Devices as follows, if necessary:

Serial Port 1 Configuration: COM1:3F8h -IRQ4
Serial Port 2 Configuration: COM2:2F8h -IRQ3
Parallel Port Configuration: LPT1:378h - IRQ7

– If you want your server to be accessed from a remote console (for

instance from a remote support center or from a remote help desk) via
the remote support modem, perform the following:

– Enable “Console Redirection Control” for the COM port to which

your modem is attached.

– Set the “Serial Port Baud Rate” to “38400 Baud.”
– Set “Hardware Flow Control” to “CTS/RTS & Carrier Detect.”

Note: Enabling Console Redirection increases the Diagnostic Partition boot
timeout from 10 seconds to 2 minutes. This allows more time to dial into a
system as it is rebooting - for example after setting a remote password.

– When all of the options on this System Board screen have been set,

press Esc to return to the previous screen.

7. Before beginning to change device configuration settings, consider the

following:
– Ensure that the IRQ, port address and I/O address for the device are

not in conflict with any other device on the system. Conflicts are
typically detected by the SCU automatically.

– Ensure that any device-specific configuration options are set

correctly. For example, for network cards with multiple connectors,
specify the connector type as appropriate for your system.

Highlighting a PCI entry and pressing Enter displays the “Enabled:
Current Configuration” option by default. To change the device’s IRQ
assignment, press Enter to change to “Enabled: Manual Configuration.”
Press F6 which enables you to change “Resources.”

Overview

Overview

Servers have special requirements regarding high availability and fast mean­time-to-repair (MTTR). If a server is down, the system’s users are also down
and losing productivity.

NCR recommends that you connect a modem to your server to enable remote
serviceability and availability of the system. You can set up your system so
that a knowledgeable person at a remote console can perform server
management and support functions. You can also use the modem for other
purposes when it is not required for remote support.

Using the server’s remote support capabilities, skilled personnel can perform
the following tasks from a remote location:

• Configure a system

• Diagnose problems

• Perform some system repairs

• Transfer files

They do not need to be on site to solve most problems.
This chapter deals mainly with configuring and using the remote support

capabilities of your server. It discusses server management software only as it
pertains to remote support.

This section provides an overview of the components involved in remote
access and management.

Definitions

In this chapter, “the server” refers to a server which is being managed from a
remote location. “Remote location” or “remote terminal” refers to the console
or client machine from which remote server management is being performed.

“Console redirection” is the ability to redirect the system console and
manipulate it from a remote location.

Overview

Server Monitor Module

The Server Monitor Module (SMM) is an ISA adapter card that has its own
processor, memory, and battery power. The SMM provides additional
diagnostic, monitoring, and management capabilities that supplement those
available in your server management software.

For information about using the SMM to perform remote management
functions, refer to the section, “Using the Server Monitor Module for Remote
Management,” at the end of this chapter.

2-4 MP-RAS Remote Support

Preparing the Server for Remote Management

Preparing the Server for Remote
Management

Remote management functions and console redirection support are available
through the following:

• Base BIOS and operating system services used with the remote support

modem

• The Server Monitor Module (SMM) and its associated software

For information on using the SMM, refer to the section, “Using the Server
Monitor Module for Remote Management,” at the end of this chapter.

To use the base BIOS and operating system services for remote management,
you must perform the following actions:

• Enable console redirection. Refer to the section, “Console Redirection,”

later in this chapter for more information.

• Enable remote access through a Hayes-compatible modem. Refer to the

section, “Configuring a Remote Support Modem,” later in this chapter for
information about configuring the modem.

• Verify that the system is correctly set up for remote management by

performing the test described in the section, “Verifying That Remote
Support Is Functioning Properly,” later in this chapter.

Note: If you want to run hardware diagnostic and configuration utilities from
a remote location with no user intervention, make sure that the server’s boot
disk contains the Diagnostic Partition. Refer to the NCR S46 Server User
Guide, Chapter 3, “Hardware-Related Utilities and Applications,” for a
discussion of the Diagnostic Partition.

NCR S46 Server MP-RAS Support Guide 2-5

Console Redirection

Console Redirection

Console redirection is a BIOS and operating system feature that enables a
person at a remote location to control your server’s console operations.

Enabling Console Redirection

You can enable console redirection at the BIOS level with either the System
Configuration Utility (SCU) or the BIOS Setup Utility. Normally you use the
SCU to perform this function.

You can also enable console redirection through your operating environment.
Refer to your operating environment documentation or to the operating
system-specific sections at the end of this chapter for more information.

Enabling console redirection increases the Diagnostic Partition boot timeout
from 10 seconds to 2 minutes. This permits more time to dial into a system as
it is rebooting - for example, after you set a remote password.

Note: Before changing console redirection parameters via BIOS Setup or the
SCU, make sure that there is no active modem connection.

Enabling Console Redirection with the SCU

The following table defines the SCU options that must be set to enable console
redirection. These options are found in various functional groups of the
System Board device definition. (Use the SCU’s “Step 3: Change
Configuration Settings” menu option to configure System Board options.)

How Redirection Works

During console redirection, the remote terminal (a system with a modem
running a package such as PROCOMM PLUS) sends keystrokes to the local
server, which then passes back video information.

Information from the local server’s video buffer is sent to the remote terminal
for display. Keyboard information from the remote terminal is forwarded to
the local server’s application using the INT 16h BIOS Keyboard Services
interrupt.

Console Redirection

Keyboard Input

Keyboard strings are based on the ANSI BBS terminal standard. Since these
terminals do not support all of the keys on the standard 101-key U.S.
keyboard, some combinations of keyboard characters are defined to represent
keys such as the following:

• F5 through F12

• Alt+A through Alt+Z

• Alt+0 through Alt+9

• Page Up and Page Down

The server application must interpret these non-standard character
combinations correctly.

Keyboard strings are fully defined in the “Key Mapping for Non-ASCII Keys”
section later in this chapter.

NCR S46 Server MP-RAS Support Guide 2-9

Console Redirection

Video Display

A screen is not painted/repainted at the remote terminal until the local video
console is updated. Therefore, when you first connect a remote terminal to the
local server, nothing may display at the remote site. This is because no video
changes have occurred since the last screen was output to the COM port.

If you connect to the local server and no video information displays at the
remote terminal, press the Enter key to generate a change to the local screen.
This should trigger the output of the video buffer to the local terminal.

Note: DOS-based applications should be tested to verify BIOS redirection
support since this support relies on BIOS video and keyboard services in order
to operate.

Console Redirection Limitations

Following are some console redirection limitations:

• BIOS console redirection does not transmit bitmap graphics (such as the

server logo screen that displays before the SCU is invoked); only
character-based data are transmitted. Therefore, a blank screen (or gray
screen in PROCOMM) may display on the remote terminal. Press Enter
to continue.

• When the server reboots, there is no output from the COM port until the

POST sequence initializes this port. This process may take some time if a
large amount of memory must be tested. The remote terminal screen
continues to display the last contents of the video buffer before the system
reboot until BIOS POST initializes the COM port.

• To reboot the server remotely, you must either enter the init command

from UNIX or select the reboot option provided on the Diagnostic
Partition and Platform CD-ROM menus, and in the SCU, BIOS Flash,
and Diagnostics Utilities. (If you enter Control+Alt+Delete at a remote
terminal, only the remote terminal is rebooted.)

• You cannot execute the DOS edit.exe program remotely because the

program uses Alt + keystrokes in its menu code. Use other DOS utilities,
such as the type command, to view text files.

2-10 MP-RAS Remote Support

Console Redirection

Timing problems in the remote interface can occur since the Esc key is both a
valid keystroke (for example, to exit a program) and the initial character in a
string that represents a keystroke (for example, Esc+OP represents F1).

Using the F1 example above, if the system takes too long to receive the
“OP” string following the Esc keystroke, redirection interprets this string
as several distinct characters. The Esc keystroke is forwarded to the
server application, followed by the “O” and “P” strings.

• For keyboard redirection to work, the application on the server must use

the INT 16h BIOS services to receive keystrokes. If the application uses
INT 9h or INT 15h services, console redirection does not work.

• Unusual key combinations (such as Control+F1) for non-ASCII keys are

not supported.

• WordPerfect does not work due to its extensive use of Shift+F1 and

Control+F1 key combinations.

NCR S46 Server MP-RAS Support Guide 2-11

Configuring a Remote Support Modem

Configuring a Remote Support Modem

NCR recommends that you connect a modem to your sever. You can use this
modem for general purpose communications and for remote management. You
can also use a Hayes-compatible modem similar to the one provided with your
server to enable remote support.

We recommend that you reserve the modem for remote support so that the
system is appropriately configured if a problem occurs.

This section discusses how to use the Diagnostic Partition menus to configure
a remote support modem. You can also perform many of these configuration
tasks through your operating system. Refer to your operating system
documentation or the operating system-specific sections at the end of this
chapter for more information.

Terms and Definitions

You should be familiar with the following terms before configuring your
remote support modem.

auto-answer mode

Mode in which your modem is configured to answer incoming calls
automatically and permit remote connections.

call-back password

Modem password associated with a call-back phone number. When you
enter a call-back password at the modem password prompt, the modem
disconnects the phone line and dials the specified call-back number.

call-through password

Modem password with no call-back phone number. When a call-through
password is entered at the modem password prompt, the remote user is
directly connected to the local server’s COM port.

2-12 MP-RAS Remote Support

Modem and System Security

The security of the server system is of primary concern when enabling remote
management. Any mechanism that permits a remote support person to enter a
system can permit an unauthorized user to enter as well.

The following security measures are recommended for enabling remote
management:

• By default, console redirection should be disabled in BIOS Setup and the

System Configuration Utility (SCU), as well as in the operating
environment. The modem should not be initialized for auto-answer mode.

• The safest mechanism for allowing remote access by expert personnel is

to define call-back passwords to assure the integrity of the remote user.
However, this is not possible in all cases, especially if modem pools are
used by support personnel (like NCR support).

Configuring a Remote Support Modem

• If call-back passwords are not possible in your support environment,

remote access should typically be disabled.
Access can be permitted in server down situations by locally enabling

redirection and locally setting a modem for auto-answer.
A person sitting at the machine needing service enables redirection in the

BIOS and/or operating environment and initializes the modem for auto­answer. Someone should watch what is happening on the local console to
verify the integrity of the caller (to prevent unauthorized access at just the
wrong moment).

• When setting up a modem for auto-answer, always enable modem

passwords and define call-back or call-through passwords. You can
configure your modem with the Diagnostic Partition or Platform
CD-ROM utilities or with direct modem (AT) commands from your
operating environment. The sections that follow discuss modem
configuration in more detail.

• It may be impossible to enable the server for redirection locally due to the

location of the hardware or the lack of computer knowledge by local
personnel.

NCR S46 Server MP-RAS Support Guide 2-13

Configuring a Remote Support Modem

In this case, call-back passwords are required for security reasons.
Console redirection should be ENABLED by default and the modem set
for auto-answer with one or more call-back numbers defined.

A user can then dial into the modem, enter the password, receive the call­backs and perform necessary remote debug, configuration and update tasks. In
addition, if more expert support is required, you can define a call-through
password remotely.

You can use the following methods to define a call-through password:

• The “Set Remote Password” Diagnostic Partition or Platform CD-ROM

menu option

• An operating system application that transmits manually entered modem

(AT) commands to COM1 or COM2

Refer to the “Using a Remote Password” section later in this chapter.
Note: Enable call-through passwords only for the minimum time necessary to

debug and correct a system problem.

Other Modem Security Issues

The modem provides many different features. The “Remote Support” utilities
do not use some of these features.

Predefined Telephone Numbers

One of the features that is not used is the ability to store predefined telephone
numbers within the modem. This represents a security risk for your system.

The modem stores pre-defined phone numbers in the same data space as call­back and call-through passwords. Therefore, a predefined telephone number is
also interpreted as a valid password.

It is recommended that you not store telephone numbers in the modem.

2-14 MP-RAS Remote Support

Configuring a Remote Support Modem

Password Checking

Another modem feature is the ability to disable modem password checking.
The Diagnostic Partition and Platform CD-ROM modem utilities support this
feature. You can access it from the “Administer Passwords” menu of the
“Configure Modem” utility.

From the “Administer Passwords” options list, you can select “Disable All
Passwords” to disable password checking. You should not use this command
in normal operations.

If you execute the “Disable All Passwords” command after enabling the
modem for auto-answer, a caller has free access to your system console.
Although passwords are provided in the operating system environments, this is
not true at the BIOS or Diagnostic Partition and Platform CD-ROM levels.

It is recommended that you never disable password checking in the modem.

Configuring a Modem

You can access the Modem Utilities menu from either the Diagnostic Partition
or the Platform CD-ROM. The Modem Utilities menu contains functions that
enable you to do the following:

• Configure your modem type, passwords and command strings.

• Set or delete a call-through password remotely.

• Enable or disable the modem for auto-answer.

• Hang up an existing connection.

Operating system-specific utilities and commands also exist to configure your
modem. For information about these utilities and commands, see your
operating environment documentation or the operating system-specific
sections found later in this chapter.

NCR S46 Server MP-RAS Support Guide 2-15

Configuring a Remote Support Modem

This section discusses the steps necessary to configure a modem for remote

4. Select “Modem Utilities” from the Remote Support menu.

2-16 MP-RAS Remote Support

Configuring a Remote Support Modem

The system displays the Modem Utilities menu.

Enabling the Remote Support Modem

To enable the remote support modem, follow these steps:

1. Access the Modem Utilities menu as detailed in the previous section.

2. Select “Configure Modem” from the Modem Utilities menu.
Note: You must enable console redirection before you can run the Configure

Modem utility. This utility uses the COM port and baud rate specified for
redirection to program the modem.

3. The first time that you run the Configure Modem utility, verify the modem

vendor and country information. Use the following steps to perform this
function:

a. Verify the modem vendor by choosing the “1. Select Modem Vendor”

menu option. Currently, the only modem vendor is “Lasat.” If you
have any other type of modem, choose “2. Other” from the modem
vendor option menu.

If you change the modem vendor to “Other,” verify all modem (AT)
command strings using the “Configure Modem” menu option “4.
Define Modem Strings.”

If your modem provides password and/or country support, or if it
does not operate correctly after you define your modem strings,
contact the appropriate NCR support center defined in the NCR S46
Server Support Log.

b. Verify the country information by choosing the “3. Configure Country

Code” menu option. From the “Configure Country Code” menu,
press 1 and Enter to view and verify country code information.

If the country information is not correct, select menu option “2.
Change Country Code” from the “Configure Country Code” menu.
This menu option allows you to define the modem to operate in
another country.

NCR S46 Server MP-RAS Support Guide 2-17

Configuring a Remote Support Modem

If your country does not display for selection, contact the appropriate
NCR support center defined in the NCR S46 Server Support Log.

4. Using the “Configure Modem” utility, define one or more modem
passwords to protect your server from unauthorized use. Define call-back
or call-through passwords using the “2. Administer Passwords” option
from the “Modem Configuration” menu.

5. From the “Administer Passwords” menu, you can view all currently
defined passwords, define and delete individual call-back or call-through
passwords, and enable and disable all password checking at the modem.

For remote support, you must define at least one password and enable
password checking. Press 2 and Enter to define a password. Provide
password and optional callback number information when prompted by
the utility. After providing the information, press 4 and Enter to “Enable
All Passwords.”

Note: Password 0 contains the remote password. This is a call-through
password that can be manipulated remotely. Password 0 is automatically
modified when you enable or disable the remote password using the “Set
Remote Password” and “Delete Remote Password” programs on the Modem
Utilities menu. The next section discusses the remote password in detail.

Never enable passwords without defining at least one call-back or call-through
password. If you enable passwords but do not define a password, remote
modem access is impossible.

6. Exit from the “Configure Modem” utility by pressing 6 and Enter to exit
from the “Administer Passwords” menu, and then pressing 5 and Enter to
exit from the modem utility’s main menu.

Although the “Configure Modem” utility instructs you to reboot, do not
reboot at this time.

7. Select “Enable Auto Answer” from the “Modem Utilities” menu.

Note: For some modems, Enable Auto Answer automatically enables
password checking for security. If this is the case with the modem installed on
your server, define at least one call-back or call-through password so that you
can connect to the server from a remote location.

2-18 MP-RAS Remote Support

8. Press the keyboard’s left arrow or Esc two times to return to the main

menu of the Diagnostic Partition or Platform CD-ROM. Select “Reboot
System” from this menu.

Since both console redirection and the modem utilities interface with the
COM port, you must reboot your server to re-initialize console redirection
fully.

In some instances, redirection may not be operational when you finish
configuring the modem. Rebooting your server corrects this problem.

Using a Remote Password

When you run the modem utilities from the Diagnostic Partition or Platform
CD-ROM, they initialize the COM port and modem. The utilities transmit
modem command strings through the COM port.

Configuring a Remote Support Modem

Using the COM port and transmitting commands to the modem disrupts
console redirection functions provided by the system BIOS. A person who is
accessing the server remotely relies on console redirection to view the server
screen and input keyboard data. If redirection is disrupted by the modem
utilities, there is no remote indication of what is happening on the server
screen or what to enter at the keyboard. For these reasons, you cannot run
most of the modem utilities remotely.

For security reasons, two modem applications on the Diagnostic Partition and
Platform CD-ROM are written especially for remote use. These applications
set or delete a Remote Password.

It is important to be able to set and delete the Remote Password from a remote
location. This allows remote management of a server in a “lights out”
environment, if the server console and keyboard hardware are not easily
accessible, or if local personnel are not sufficiently trained.

In these situations, call-back passwords are required to be defined for the
server’s modem, for security reasons. Console redirection should be enabled
by default and the modem set for auto-answer with one or more call-back
passwords defined.

NCR S46 Server MP-RAS Support Guide 2-19

Configuring a Remote Support Modem

A user can then dial into the modem, enter the password, receive the call-back
and perform necessary remote debug, configuration and update tasks. In
addition, if more expert support is required, the capability exists to define a
call-through password remotely.

This call-through password is the remote password. It is automatically stored
in the modem as Password 0. When you select “Delete Remote Password,”
Password 0 is automatically cleared.

The “Set” and “Delete Remote Password” utilities are designed to initialize
and command the modem only when all necessary information has been
obtained from a remote user. After this, the COM port and modem are
initialized, the current connection is hung up, the modem is commanded, and
the system is reset to restore console redirection capabilities. No other
passwords (but Password 0) are affected. No other modem strings (except the
update password command string, at*p) are transmitted.

Note: As mentioned in the “Modem and System Security” section, you should
enable a call-through password only for the minimum time required for
support purposes. When you enable the call-through password, inform a
support person immediately and allow them access to the server through the
modem.

Configuring Other Modems

There are certain modem configuration settings required for remote
management. Review this section if you selected “Other” as your modem
vendor while running the “Configure Modem” utility.

If you do not have a Lasat Safire modem, you must verify (and maybe also
modify) the modem (AT) command strings that are used by the modem
utilities on the Diagnostic Partition and Platform CD-ROM. The exact
settings of the strings depend on the command set supported by your modem.
The following information provides guidelines regarding how to configure
your modem.

2-20 MP-RAS Remote Support

Configuring a Remote Support Modem

You can use the Configure Modem utility to edit the modem (AT) commands
used by the Diagnostic Partition and Platform CD-ROM modem utilities.
Refer to the “Enabling the Remote Support Modem” section earlier in this
chapter and to the NCR S46 Server User Guide, Chapter 3, “Hardware-
Related Utilities and Applications,” for additional information about using the
Configure Modem utility.

Note: You can edit any modem (AT) command strings used by the modem
utilities on the Diagnostic Partition or Platform CD-ROM. However, because
the CD-ROM is a read-only device, these changes are made to a RAMDisk
file. The changes are in effect from the time you enter them until the next
reboot of the system. At system reboot, the RAMDisk and its contents are
lost.

General Modem Configuration Requirements

Configure the remote access modem to perform as follows:

• Operate at the same line speeds as console redirection. Some modems

remember the last line speed used. These modems might not operate
correctly if they are initialized at one speed (for example, 9600 baud) and
redirection is set for a different speed (for example, 19.2 K baud).

• Force the Carrier Detect line to follow Off-Hook/ On-Hook.

• Not return result codes or only provide result codes in originate mode.

• Operate with echo off.

• Maintain settings across sessions.

• Ignore the DTR signal line. The modem must ignore DTR since this line

toggles low when the server is rebooted. Ignoring the DTR line allows the
modem to maintain a session through system reboot.

For example, assume that a remote reboot invokes a new hardware
configuration. In this case, the modem must maintain the remote session
so that support personnel can verify that the system boots correctly and
problems have been resolved.

Preparing the Remote Location

Preparing the Remote Location

This section describes how to prepare a system to act as a remote terminal
when remote management of your server is required.

This section provides instructions to configure PROCOMM PLUS, Version

3.0. PROCOMM PLUS is the only communications program tested to date
that fully supports the ANSI BBS standard and ANSI color. In addition, you
can configure extended keyboard mapping information with PROCOMM
PLUS.

General Requirements

To support a system from a remote location with PROCOMM PLUS, Version

3.0, you need the following:

• Analog phone line (digital phone lines do not work with the modem)

• High speed modem (a 28.8 Kbps modem is recommended if you are

running console redirection at 38.4 K baud speeds. However, you can also
use a 14.4 K bps modem if you reduce the redirection speeds
accordingly.)

• Windows operating environment (Windows 3.1, Windows NT, or

Windows 95)

PROCOMM PLUS Settings

Information in this section is based on the following assumptions:

• You performed an Express Install of PROCOMM PLUS, Version 3.0.

• PROCOMM is defined to operate on COM1 or COM2 with your remote

support modem

• You selected a default window setup

NCR S46 Server MP-RAS Support Guide 2-23

Preparing the Remote Location

To connect to the server, run the PROCOMM PLUS Terminal application.
You can select this application from the PROCOMM PLUS Program

software:

1. Press Alt+F8 to start the PROCOMM PLUS Keyboard Editor utility. Use
the keyboard mapping information provided in the sections “Keyboard
Input” and “Key Mapping for Non-ASCII Keys” to define valid keystroke
combinations required by the console redirection software. Save the
keyboard information to a keyboard file, S46.kbd.

2. Using the PROCOMM PLUS Connection Directory, define a new Data
entry that represents the server to be managed remotely. As part of this
definition, provide the following information:

– Phone number of the analog line that connects to the server
– The type of connection: internal, local, long distance or international
– Selection of COM1 or COM2 and your remote support modem for the

“Data Connection.” This may be the “Current Connection”
PROCOMM default.

– Terminal type = ANSI BBS
– Parity = None
– Data bits = 8
– Stop bits = 1
– Protocol = Zmodem

3. After defining the data entry, select “OK” to continue and then select
“File/Save” from the Connection Directory action bar. You can now
return to the “Terminal” window to continue defining the terminal
parameters.

4. Select the Setup/Data/Terminal Options menu items from the “Terminal”
action bar. Define the following parameters on the “Terminal Options”
window:

– Terminal Size = 25 Rows and 80 Columns

2-24 MP-RAS Remote Support

Preparing the Remote Location

– Terminal Keyboard File = S46.kbd (You can edit this file from the

Terminal Options menu by pressing the “Edit Keyboard File” button.)

– Toggle support OFF for “Line Wrap” and “Destructive Backspace”
– Select the “Advanced” button and toggle “Treat Music sequence as

Delete Line” ON

5. From the button list at the left of the current window, select “Data

Connection.” Verify that the “Use hardware flow control” toggle is ON.

6. From the button list at the left, select “Terminal Fonts.” Verify that the

“PCPlus 437” font is selected.

background color to black.

8. Press the “OK” button at the bottom left corner to save the terminal

parameter settings.

9. To dial the modem, open the “Connection Directory” and the “Data”

window. Highlight the entry that represents the S46 server to be remotely
managed. Select the “Dial” button at the bottom right of the window.

Additional PROCOMM settings may be required to transfer files. Several
options are possible. Refer to the “Transferring Files To and From a Remote
Location” section later in this chapter for details.

NCR S46 Server MP-RAS Support Guide 2-25

Preparing the Remote Location

Keyboard Input

The local server maps keyboard input from the remote console as follows:

If the key... Then...

Has an ASCII mapping
(such as A or

Does not have an ASCII
mapping (such as F5 or

Page Down

Control+A

)

)

The ASCII character typed at the remote console
is transmitted directly to the local server and
placed in the local server’s keyboard buffer.

The character typed at the remote console is
translated by the PROCOMM software to the
keystroke combination defined in the Keyboard
File. This combination is then transmitted to the
local server. The local system translates the
keystroke combinations back to the appropriate
keyboard character and places the character in
the local keyboard buffer.

The tables in the following sections define key mappings expected by BIOS
and UNIX MP-RAS console redirection software. You can define these
mappings in PROCOMM PLUS by performing the following actions:

• Pressing Alt+F8 in the “Terminal” window to start the PROCOMM
Keyboard Editor utility

• Selecting a key to be defined from the displayed keyboard by tabbing to
the key or pressing the left mouse button when the cursor is positioned
over the key

• Pressing the Spacebar to edit the key’s mapping

• Defining the “Normal” key combinations as documented in the sections

that follow

2-26 MP-RAS Remote Support

If you do not want to define all of the keyboard mapping settings individually,
you can obtain a PROCOMM keyboard file, REMCON.KBD, from the NCR
World Wide Web site. To this file, perform the following:

• Use a Web Browser to connect to the www.ncr.com Web site.

• The URL to obtain the REMCON.KBD file is

http://www.ncr.com/support/pc/pcdesc/library/4300.shtml.

• Select “Remote Console (S40 and 4300) keyboard remapping file for

Procomm.”

NCR S46 Server MP-RAS Support Guide 2-29

Verifying That Remote Support Is Functioning Properly

11. Define a call-back or call-through password for the modem, as described
in the “Enabling the Remote Support Modem” section earlier in this
chapter. (If you are defining a call-through password, define it as
Password 0.)

12. From the Modem Utilities menu, select “Enable Auto Answer.”

13. Press the keyboard’s left arrow or Esc twice to return to the main menu of
the Diagnostic Partition or Platform CD-ROM. Select “Reboot System”
from this menu.

14. Press D (when prompted) to enter the Diagnostic Partition, or boot from
the Platform CD-ROM.

15. Select “Run Utilities and Diagnostics from the MS-DOS Startup menu if
you booted to the Diagnostic Partition. Select “Run CD Utilities and
Diagnostics” if you booted from the Platform CD-ROM.

The main menu of the Diagnostic Partition or Platform CD-ROM should
display.

At this point, a remote location must be configured to access your server and
verify the operation of the remote management components. You can do this
yourself, or contact the appropriate NCR support center. A list of NCR
support numbers is available in the NCR S46 Server Support Log.

Verifying Remote Management Operation

To verify the operation of the remote management components, follow these
steps:

1. Configure and dial from a remote terminal with PROCOMM PLUS as
described in the “Preparing the Remote Location” section earlier in this
chapter.

2. Enter your call-back or call-through password when prompted by the
modem.

– If you use a call-through password and enter it successfully, you

should see the Diagnostic Partition or Platform CD-ROM main menu
on your remote terminal.

2-30 MP-RAS Remote Support

Verifying That Remote Support Is Functioning Properly

– If you use a call-back number, your current call is disconnected and

the modem dials the call-back number. The server transmits the
Diagnostic Partition or Platform CD-ROM main menu to the remote
terminal after the call-back connects successfully.

3. From the remote terminal, select the following in sequence from the

Diagnostic Partition or Platform CD-ROM menus:

– System Config Utils
– View Version Information
– View S/W Version

Verify that the version information displays exactly as it displays when
“View S/W Version” is selected from the local console.

4. Press Esc twice to exit the “View Version Information” utility and return

to the Diagnostic Partition or Platform CD-ROM main menu.

5. If you accessed the server with a call-through password, select the

following in sequence from the menus:

– Remote Support
– Modem Utilities
– Delete Remote Passwd

As part of the “Delete Remote Passwd” processing, the system disables
the call-through password, disconnects your call, and reboots the server.

6. If you accessed the server with a call-back password, disconnect the call

using the Hang Up button in the upper right corner of PROCOMM’s
“Terminal” window.

7. Remove all non-production or test-related call-back or call-through

passwords from the local console. To do this, follow the instructions in the
next section.

NCR S46 Server MP-RAS Support Guide 2-31

Disabling Remote Support Passwords and Modem Access

Disabling Remote Support Passwords and
Modem Access

Remote management capabilities are disabled differently in different
situations. This section discusses these situations in detail.

Disabling Modem Passwords When Operating Remotely

If you are using a call-through password to operate remotely and have
completed debug and repair of a system, it is necessary to delete the password.

From the Diagnostic Partition or Platform CD-ROM environments, select
“Delete Remote Password” from the Modem Utilities menu. It is important to
perform this function because the remote password is a call-through password
that permits anyone who types it correctly to access your server’s console.

If you are using a call-back number to operate remotely and have completed
debug and repair, you do not need to do anything to disable remote support.
You should hang up the current connection using PROCOMM’s Hang Up
button in the upper right corner of the “Terminal” window.

You cannot disable a call-back password remotely. This requires the ability to
execute the modem utilities remotely on the Diagnostic Partition or Platform
CD-ROM. As discussed in the section, “Using a Remote Password,”
execution of most of the modem utilities is not possible from a remote
location.

Disabling Modem Passwords and Access from the Local
Server

To disable remote support when operating from the local server, first select
“Hang Up” from the Modem Utilities menu on the Diagnostic Partition or
Platform CD-ROM.

If you defined a call-through password (or a call-back password that is no
longer needed), follow these steps to delete this password:

2-32 MP-RAS Remote Support

Disabling Remote Support Passwords and Modem Access

1. Select “Configure Modem” from the Modem Utilities menu on the

Diagnostic Partition or Platform CD-ROM.

2. From the Configure Modem main menu, press 2 and Enter to Administer

Passwords.

3. From the Administer Passwords menu, press 3 and Enter to Delete

Password.

4. At the prompt, enter the number of the password to be deleted.
If you are operating locally and want auto-answer mode to remain active, no

further action is required.
If you are operating locally and want to disable modem call-back or call-

through access, select “Disable Auto Answer” from the Modem Utilities menu
on the Diagnostic Partition or Platform CD-ROM. After you disable auto­answer, remote modem access is prevented until you select “Enable Auto
Answer” or until you dial out from the server through the modem.

Note: If you enable your modem for auto-answer, the command string that
performs this function also enables password checking.

Limitations of “Disable All Passwords”

You cannot disable remote access by selecting the “Disable All Passwords”
option from the Configure Modem menu. This option disables password
checking only.

If you select “Disable All Passwords” after enabling the modem for auto­answer, a caller has free access to your system console. Although operating
system environments provide passwords, this is not true at the BIOS or
Diagnostic Partition and Platform CD-ROM levels.

It is recommended that you never disable password checking for the modem.

Transferring Files To and From a Remote Location

Transferring Files To and From a Remote
Location

This section explains how to send files to and from your server.
You can perform the following types of file transfers from the Diagnostic

Partition or Platform CD-ROM menus:

• Download files from a remote location to the server

• Upload files from the server to a remote location

After you download or upload files, the server must be rebooted before you
can perform further operations from the remote console. By default, the
download and upload commands reboot the server after the file transfer is
complete.

You can prevent these commands from rebooting automatically. However, if
you do so, you must reboot the server locally using the Reboot System menu
item in the Diagnostic Partition or Platform CD-ROM menus. Until the
system is rebooted, remote management of the server is disabled.

PROCOMM Settings

You can use either the default ZMODEM protocol or the YMODEM protocol
to transfer files.

ZMODEM Settings

The following table shows the PROCOMM software settings required to use
the ZMODEM protocol.

Option Required Setting

Receiver Crash Recovery Crash Recovery Off
Receiver Overwrite Options Always Overwrite
Sender Crash Recovery Crash Recovery Off
Sender Overwrite Options Always Overwrite

NCR S46 Server MP-RAS Support Guide 2-35

Transferring Files To and From a Remote Location

Option Required Setting

Transmit Window 2k - Window

This setting is necessary when transmitting
large files to your server at 38.4K baud. This
alleviates (but does not eliminate) a problem
where ZMODEM detects “Bad CRC” and
resends many packets. If file downloads are
terminated due to excessive retries, use

19.2K baud.

Verify these settings (and modify them if necessary) by selecting
Setup/Data/Transfer Protocol from PROCOMM’s Terminal window action
bar. Follow these steps from the Transfer Protocol window:

1. Select “Change Settings” for “Receiver Crash Recovery” Settings.

2. Set the individual “Crash Recovery” and “Overwrite” options as specified
in the table.

3. Select “Change Settings” for Sender Crash Recovery Settings.

4. Set the individual “Crash Recovery” and “Overwrite” options as specified
in the table.

5. Select “Transmit Method” and select “2K-Window.”

YMODEM Settings

If you plan to use the YMODEM protocol, make sure that you select the crash
recovery option, “Overwrite existing file.”

Note: You can change the transfer protocol from ZMODEM to YMODEM
by selecting “Setup/Data/Transfer Protocol” from PROCOMM’s Terminal
window action bar. From the Transfer Protocol window, select the down
arrow button to the right of the Current Transfer Protocol list box.

Downloading Files

To download files from a remote location to the server, follow these steps:

1. Boot to the Diagnostic Partition or Platform CD-ROM.

2-36 MP-RAS Remote Support

Transferring Files To and From a Remote Location

2. Select “Run Utilities and Diagnostics” from the MS-DOS Startup menu

of the Diagnostic Partition. Select “Run CD Utilities and Diagnostics” if
you booted from the Platform CD-ROM.

3. Select “Remote Support” from the main menu.
Note: If the Diagnostic Partition is not installed and you are executing from

the Platform CD-ROM, you must first select “Execute Utils from CD.”

4. Select “File Transfer Utils” from the Remote Support menu.

5. Select “File Download” from the File Transfer Utilities menu.

The system transfers you to a DOS shell and displays a DOS prompt.

6. Use the rf command to download files. The next section explains how to

use this command. You can obtain a list of valid command line options by
entering rf -h at the DOS prompt. Default settings for the various rf
command line options are defined in the file transfer configuration file,
ft.cfg, discussed later in this section.

7. If you specify the -r command line option for the rf command, your server

does not reboot after the file transfer, and console redirection is disabled.
Be sure to reboot the server locally using the Control+Alt+Delete key
sequence from the DOS prompt, or the “Reboot System” menu item from
the Diagnostic Partition or Platform CD-ROM main menu.

Using the rf Command

Use the rf (receive file) command to download files from a remote location to
the server. Note the following when using the rf command:

• By default, the rf command uses the ZMODEM protocol for file transfer.

You can specify a command line option that lets you use the YMODEM
protocol.

• By default, the rf command automatically reboots the server after file

transfer is complete. You can specify a command line option that prevents
automatic reboot. If you specify this option, you must reboot the server
locally before you can perform further remote operations.

NCR S46 Server MP-RAS Support Guide 2-37

Transferring Files To and From a Remote Location

• To reboot the server, use the Control+Alt+Delete key sequence from the
DOS prompt or select “Reboot System” from the Diagnostic Partition or
Platform CD-ROM main menu.

• The requirement to reboot your server after executing the rf command
implies that you should download all files with one rf command rather
than using a series of rf commands.

Note: If you do not automatically reboot your server after executing the rf
command, you may experience screen corruption. To correct this, immediately
perform a system reboot.

The syntax for the rf command is the following:

Seconds to wait before sending file(s) from a
remote location

Note: You have approximately 30 seconds
after the specified wait period to send the file
from a remote location. If the file is not
received in this time period, the rf program
assumes that the file transfer failed. For
example, using the default of 8 seconds, you
must send the file from a remote location
between 8 and 38 seconds after the entering
the rf command.

-y Use YMODEM for file transfer.

Note: When running the rf utility from the Platform CD-ROM, be sure to
download a file to a “real” directory. When running from the Platform CD­ROM, your current directory may be a RAMDisk. (You can determine if you
are in a RAMDisk directory by entering the DOS dir /p command and
checking the volume name. If the volume name is MS-RAMDRIVE, then you
are running from a RAMDisk directory.)

If the current directory is a RAMDisk directory and you did not override the
download directory setting, files are downloaded to the RAMDisk. In this
case, when the server is rebooted (which must occur after the execution of the
rf command), the RAMDisk directory and its contents are lost.

NCR S46 Server MP-RAS Support Guide 2-39

Transferring Files To and From a Remote Location

Download Filenames

The rf utility assigns the filenames specified at the remote (sending) location.
You cannot override these filenames.

rf Example

Use the rf command to start the receive file program on the remote server.
If the file transfer configuration file (ft.cfg) has not been modified, the

program waits about 8 seconds before it expects to start receiving files from
the remote location. If ft.cfg does not specify a download directory and you
did not specify a directory name with the -dd option, files are placed in your
current directory. The filenames are the same as those specified at the remote
(sending) location.

Uploading Files

To upload files from the server to a remote location, follow these steps:

1. Boot to the Diagnostic Partition or Platform CD-ROM.

2. Select “Run Utilities and Diagnostics” from the
MS-DOS Startup menu of the Diagnostic Partition. “Select Run CD
Utilities and Diagnostics” if you booted from the Platform CD-ROM.

3. Select “Remote Support” from the main menu.

Note: If the Diagnostic Partition is not installed and you are executing from
the Platform CD-ROM, you must first select “Execute Utils from CD.”

4. Select “File Transfer Utils” from the Remote Support menu.

5. Select “File Upload” from the File Transfer Utilities menu.
The system transfers you to a DOS shell and displays a DOS prompt.

6. Use the sf command to upload files. The next section explains how to use
this command. You can obtain a list of valid command line options by
entering sf -h at the DOS prompt. Default settings for the various sf
command line options are defined in the file transfer configuration file,
ft.cfg, discussed later in this section.

2-40 MP-RAS Remote Support

Transferring Files To and From a Remote Location

7. If you specify the -r command line option for the sf command, your server

does not reboot after the file transfer and console redirection is disabled.
Be sure to reboot the server locally using the Control+Alt+Delete key
sequence from the DOS prompt, or the “Reboot System” menu option
from the Diagnostic Partition or Platform CD-ROM main menu.

Using the sf Command

Use the sf (send file) command to upload files from the server to a remote
location. Note the following when using the sf command:

• By default, the sf command uses the ZMODEM protocol for file transfer.

You can specify a command line option that lets you use the YMODEM
protocol.

• By default, the sf command automatically reboots the server after file

transfer is complete. You can specify a command line option that prevents
automatic reboot. If you specify this option, you must reboot the server
locally before you can perform further remote operations.

• To reboot the server, use the Control+Alt+Delete key sequence from the

DOS prompt or select “Reboot System” from the Diagnostic Partition or
Platform CD-ROM main menu.

• The requirement to reboot your server after executing the sf command

implies that you should upload all files with one sf command rather than
using a series of sf commands.

Note: If you do not automatically reboot your server after executing the sf
command, you may experience screen corruption. To correct this, immediately
perform a system reboot.

The syntax for the sf command is:

-y Use YMODEM for file transfer

1-60 (8)

Seconds to wait before sending file(s) to a
remote location

Note: You have approximately 30 seconds
after the specified wait period to send the
file(s) to a remote location. The wait period
allows time to prepare the remote system to
receive the file(s). If the remote location does
not acknowledge the request to send the
file(s) in this time period, the sf program
assumes that the file transfer failed. For
example, using the default of 8 seconds, the
remote system must acknowledge and begin
processing the request to send file(s)
between 8 and 38 seconds after you enter the

sf command.

Specifying sf Filenames

You can send multiple files using a single sf command. If you enter multiple
file names on the sf command line, separate file names with a blank space.

Alternately, you can define a list of filenames in an ASCII file (one name per
line). Use the -l command line option to specify this ASCII file name when
you enter the sf command.

sf Examples

The following command sends the config.sys and autoexec.bat files from the
server to a remote location via ZMODEM:

sf c:\config.sys c:\autoexec.bat

The following command sends one or more files which are listed (one per line)
in the c:\files.txt file:

sf -l c:\files.txt

NCR S46 Server MP-RAS Support Guide 2-43

Transferring Files To and From a Remote Location

For example, the c:\files.txt file might contain the following list of files to be
sent:

c:\autoexec.bat
c:\config.sys
c:\log\error.txt

File Transfer Configuration File

You can use the file transfer configuration file, ft.cfg, to set default options for
the sf and rf commands. Unless you move this file, it is located in the same
directory as the sf and rf executable files, \REMOTE.

Runtime options that you specify on the command line override default
options specified in the configuration file.

Editing the ft.cfg File

You can use any DOS ASCII file editor to modify the ft.cfg file in the
Diagnostic Partition. You can also edit the ft.cfg file if you boot from the
Platform CD-ROM.

Because the CD-ROM is a read-only device, you must follow these steps to
edit and use the ft.cfg configuration file on the CD:

1. Copy the file from CD to RAMDisk (x:\tmp where x is the RAMDisk
directory) or some other writeable file system (for example, the A:\ drive).

Note: You can determine whether you are in a RAMDisk directory by
entering the DOS dir /p command and checking the volume name. If the
volume name is MS-RAMDRIVE, then you are running from a RAMDisk
directory.

2. Use any DOS ASCII file editor to change and save the file.

3. Use the -f command line option to specify the correct configuration file
directory when you enter an sf or rf command.

Modem Configuration in UNIX MP-RAS

Modem Configuration in UNIX MP-RAS

To enable console redirection while UNIX MP-RAS is running, enter the
following command:

contty -s /dev/tern/00 -b 38400 -p

where the -b parameter specifies the redirection baud rate.
To access the server’s BIOS and MP-RAS consoles from a single remote

terminal running PROCOMM PLUS, you must specify the “ansi-bbs”
terminal type in MP-RAS. Use the following instruction to specify this:

TERM = ansi-bbs

To send an initialization string to the remote support modem, use the
following command:

/usr/lib/uucp/setmodem -d -m safire288init /dev/term/00
Note: The setmodem command uses information in the /etc/uucp/Dialers file

to initialize the modem. The modem command in the Dialers file is designed to
work with the default settings of the Diagnostic Partition and Platform CD­ROM modem utilities, and the default configuration of BIOS-level console
redirection.

If you change the modem command string in the Dialers file and send the
modified command to the modem, it might configure the modem incorrectly
for BIOS redirection. A similar problem might occur if an MP-RAS
application reconfigures the modem.

If you experience problems when performing BIOS-level redirection, go to the
Diagnostic Partition or Platform CD-ROM’s Modem Utilities menu and select
“Enable Auto Answer.” This synchronizes your modem with the current
BIOS-level redirection settings.

Setting Modem Passwords in UNIX MP-RAS

Some modems provide call-through and call-back password support. The
modem provided with your server supports these passwords.

NCR S46 Server MP-RAS Support Guide 2-47

Modem Configuration in UNIX MP-RAS

When using call-through passwords, the modem does not connect to the server
system until the user at the remote system enters a valid call-through
password. Do not confuse this with the operating system login password. The
call-through password must be entered first and is in addition to any operating
system login password.

For modem setup for remote management, the call-through password provides
a level of security when the server is out-of-service (for example, when the
operating system is not running).

Call-back passwords are similar to call-through passwords except, a call-back
password requires a call-back phone number as well as a password.

With MP-RAS, there are two basic ways to set up either type of modem
password. One is to include the passwords in the modem initialization strings
in the /etc/uucp/Dialers file. You can edit the initialization string directly with
any editor program or modify it using the sysadm menus under the following
tasks:

<network_services>
<modem_setup>

Another method for defining a modem password is to connect directly to the
modem using the cu utility and issue the appropriate modem commands.

For the Lasat Safire 288 modem, there are up to four passwords for use as
either call-back or call-through passwords. The format of the modem
command to set passwords is as follows:

AT*Px:password:call-back_number

where

• x is the password number (0-3)

• password is the modem password, comprised of at least 6 and no more

than 12 alphanumeric characters

• call-back_number is the optional call-back phone number. The call-
back_number is comprised of up to 22 numbers and dialing characters

(dashes, commas and parentheses). When you set a call-through
password, omit the call-back number and its preceding colon.

2-48 MP-RAS Remote Support

Modem Configuration in UNIX MP-RAS

Note: If you enter a password that contains less than 6 or more than 12
characters, the password currently stored at the specified password number is
deleted. Also, the modem returns an error indicating that an invalid password
was entered. Use this mechanism to manually delete a password.

The following table lists other password-related AT commands:

Command Description

at*c1 enable password checking at the modem
at*c0 disable password checking at the modem
at*l list all currently defined passwords

Sample cu Session

Following is a sample cu command session that shows how to set the modem’s
password 0 to NCRONLYS46 in call-through mode. The example assumes
that you have a Lasat modem connected to the COM1 serial port. Commands
typed by the user are in bold, system responses are in normal font, and
comments on the sequence are in italics.

1. Starting at the shell prompt, enter:

# cu -lterm/00

The system displays:

Connected

2. Enter:

ATE1Q0

This command enables echo and OK responses. The modem may not echo
this command back to you. The system displays:

OK

3. Enter:

AT*P0:NCRONLYS46

This command sets the call-through password. The system displays:

OK

NCR S46 Server MP-RAS Support Guide 2-49

Modem Configuration in UNIX MP-RAS

4. Enter:

AT*C1

This command enables password checking. The system displays:

OK

5. Enter:

ATZ

This command restores the modem state to no echo.

6. Enter the following to end the cu session:

~

The system displays:

Disconnected
#

Note: Password 0 contains the remote password. The remote password is a
call-through password that can be manipulated from a remote location. It is
discussed in detail earlier in this chapter in the “Using a Remote Password”
section.

Password 0 is automatically modified when you enable or disable a password
using the “Set Remote Password” and “Delete Remote Password” menu items
on the Diagnostic Partition and Platform CD-ROM Modem Utilities menu.

Setting Passwords in the Dialers File

The alternate way to set modem passwords involves adding initialization
strings to the /etc/uucp/Dialers file.

For example, assume that you want to define a call-through password of
NCRONLYS46 and a call-back password of NCRSUPPORT that dials 1-800­555-1212.

You would add the following line to the Dialers file:

safire288passwd =,­, “” \MATQ0 OK\r AT*P0:NCRONLYS46 OK\r AT*P1:NCRSUPPORT:1,80
0,555-1212 OK\r AT*C1 OK\r ATZ

2-50 MP-RAS Remote Support

To initialize the passwords specified in the Dialers file, enter the following
command at the MP-RAS system prompt:

/usr/lib/uucp/setmodem -d -m safire288passwd /dev/term/00

Other Modem Command Strings

When using the server’s modem in a UNIX MP-RAS environment, you may
also need the following command strings:

• Enable Auto-Answer - at&f0&d0l3*k1*c1e0s0=1

• Disable Auto-Answer - ats0=0

• Hang Up - ath0

• Store Current Modem Setup Permanently - at&w0&y0

• Enable Password Checking - at*c1

Modem Configuration in UNIX MP-RAS

• Disable Password Checking - at*c0

• Query Country Code - ati5

You can send these strings to the modem using the MP-RAS cu utility or the
modem utilities on the server’s Diagnostic Partition or Platform CD-ROM.

NCR S46 Server MP-RAS Support Guide 2-51

Dialing into a UNIX MP-RAS System

Dialing into a UNIX MP-RAS System

UNIX MP-RAS provides two levels of access through a system’s COM ports:

• If the contty command has been issued, or BIOS-level console redirection
is active, MP-RAS transfers control of the system console to a remote
user connected through the system COM port.

• If the contty command has not been issued, and BIOS-level redirection is
disabled, port monitor services control the system’s COM ports and
present a normal login prompt to a remote user.

Using the Server Monitor Module for Remote Management

Using the Server Monitor Module for
Remote Management

The Server Monitor Module (SMM) is an ISA adapter with an on-board
battery-backed CPU. It provides server management and remote access
capabilities for a server system.

SMM Features

Following is a summary of some of the features of the Server Monitor Module
hardware:

• Temperature monitoring of both an on-board and remote temperature

probe

• Voltage monitoring of key voltages in the server system

• Ability to remotely reset or power up and down the server system

• Delivery of alerts to a monitoring system or to a pager

• Ability to redirect the server console to a remote system

• Logging of system state changes and BIOS diagnostic information

The SMM provides alerts and system information to a remote console even
when the host is down or powered off.

Installing the SMM

To install the SMM, refer to the LANDesk Server Monitor Module
Installation and User’s Guide packaged with the adapter hardware. After

completing the installation of the adapter, run the SCU (System Configuration
Utility) from the Diagnostic Partition or Platform CD-ROM. See Chapter 5
for additional information about the SCU.

Add the SMM adapter to your system configuration using the SMM
configuration file, !INT0016.CFG. The default resources required by the
adapter are:

NCR S46 Server MP-RAS Support Guide 2-53

Using the Server Monitor Module for Remote Management

Parameter Default

Address C8000
IRQ 5
DMA 3

PCMCIA Modem

To provide alerting when the server is powered off or to support console
redirection functions, a PCMCIA modem (14.4 to 28.8 KB) must be installed
on the SMM. This modem can communicate with remote and server
management software or a paging service. Setting up the modem is dependent
upon the operating environment and the server administration application
installed on the system.

Software

NT users can install the NCR Server Availability Manager (SAM) to operate
with the SMM. SAM does not support console redirection at this time, but it
does support server management through the SMM.

On UNIX MP-RAS systems, add the servermon package included with the
operating system.

Information on installing and using servermon and SAM is available with
your operating system documentation.

In order to use the server management and console redirection capabilities of
the Server Monitor Module, you must install monitoring console software on a
remote system. Available software includes SAM for NT and the smmremote
package for UNIX MP-RAS. You can also use the Intel LANDesk
Manager application (Release 1.3) as a remote server management and remote
console application, running on a Windows95, 3.x or NT system.

Redirection Support With LANDesk

The Server Monitor module provides the ability to redirect console operations
to a LANDesk console system. This means that the server’s console display is
duplicated at the remote LANDesk console, and that keyboard input entered at
the LANDesk console has the same effect as keyboard input at the server
console.

The MP-RAS data file /etc/default/servermon defines operating defaults for
the Server Monitor Module. One of the parameters in this file disables and
enables console redirection. By default, console redirection is enabled at
installation. You can use the following command to disable redirection:

defadm servermon CONSOLE_REDIRECT=0

To enable console redirection at a later date, use the following command:

defadm servermon CONSOLE_REDIRECT=1

After either of these commands, you must reset the Server Monitor Module to
enable the new option settings.
