To Begin the Configuration Process
The procedures that follow describe how to modify the NMMGR configuration
filefor the introductory screens.
To Start NMMGR
Run the NMMGR program.Node manager (NM) or network administrator (NA)
capabilities are required to run this program.
To run NMMGR:
1. Type NMMGR.PUB.SYS at the system prompt (:).
2. Press [RETURN].
NOTE As of version 4.0 of the operating system, you can modify the link
configurations in NMCONFIG.PUB.SYS when the Network Services are
active. However, the network must be stopped and restarted for the
changes made in NMMGR to be implemented.
If NS is down, you will see the following two messages in response
to the NETCONTROL STATUS command:
TRANSPORT NOT ACTIVE. (NETEXPORTWARN 0001)
ENCOUNTERED ONE OR MORE WARNINGS WHILE PROCESSING
COMMAND. (CIWARN 4437)
To Open the Configuration File
The Open Configuration/Directory File screen (#1) in figure 5-2 is the
first screen displayed when you run NMMGR.
Figure 5-2. Open Configuration/Directory File Screen
Follow the steps listed here to enter data for this screen. Refer to
Fields subsection on the next page for detailed information about each
field on the screen.
Steps.
1. Verify that the correct configuration file name, backup
configuration file name, and network directory file name are in
the appropriate fields.
2. If you have assigned a write access password, enter it in this
field. If you are not using the password feature, leave this
field blank.
3. Press the [Open Config] key. If you are creating the
configuration file for the first time, NMMGR will ask you to
verify creation. Press the [Open Config] key again to continue.
Fields.
Configuration file name The only configuration file name the system
recognizes for use by the network subsystem is
NMCONFIG.PUB.SYS. You can, however, create or
modify a configuration file using a different
name and save it as an offline configuration
file. You can use offline configuration files
as a means of creating and storing
configurations that you want to use in the
future or that you are preparing for use on a
different system. When you are ready to use an
offline configuration file, rename it as
NMCONFIG.PUB.SYS and reboot the system. (Keep
in mind that any file you use as a
configuration file must be successfully
validated before you try to use it.)
Backup configuration A backup file namemust be specified whenever a
file name configuration file is opened or created. The
default backup configuration file name is
NMCBACK.group.account. The backup file will be
automatically updated with the contents of the
configuration file each time the configuration
file is successfully validated.
Network directory file For LAN links using domain name services, you
name do not need to configure the network directory.
For LAN links using probe or ARP, you need to
configure the network directory only for nodes
that are to communicate with an internetwork or
if non-HP nodes are on the LAN. The only
network directory file name supported by HP is
NSDIR.NET.SYS. This file is part of a KSAM
pair. A key file is created at the same time
as this data file. The key file will
automatically be named using the first six
letters of the network directory file name,
appended with the character K. For example,
NSDIRK.NET.SYS is the name of the key file
associated with the data file NSDIR.NET.SYS. If
the name of the data file is less than six
letters long, then the entire file name would
be appended with a K.
Write access password The password is an optional feature. If a
password has been assigned, you must enter it
in the password field to update the
configuration file or the directory file. It
is still possible to open an existing file
without using an assigned password, but the
file will be in read only mode and NMMGR will
not accept changes.
If a password has not been assigned, you should
ignore the password field.
If you want to assign a password for the system
you are configuring, see Using the Node
Management Services (NMS) Utilities.
To Select NS Configuration
The Main screen (#2)in figure 5-3 is displayed after you create or open a
configuration file by pressing the [Open Config] key from the Open
Configuration Directory File screen (#1) in figure 5-2.
Figure 5-3. Main Screen
NOTE NS/SNA is no longer offered as a product and has been removed from
the Corporate Price List. The product is obsolete with no plans
for support.
Steps.
1. Ensure that the information in the fields on this screen is
correct. If not, or if the information has not been entered,
specify the correct information and press the [Save Data] key.
(See Configuring Systems for Terminals, Printers, and Other Serial
Devices for information about configuring the information on this
screen.)
2. When you are satisfied with the information as configured, press
the [NS] key to select the NS configuration branch.
Fields.
Local node name The local node name is the name by which the
Series 900 HP 3000 computer is known in the
network. The format of a node name is
nodename.domain.organization where the total
number of characters is 50 or fewer, and each
field contains 16 or fewer characters
(alphanumeric, underscore, or hyphens). The
first character of each field must be
alphabetic.
The nodename portion of each node name must be
unique within the node's network. The
nodename.domain portion of each node name must
be unique within the internetwork. HP
recommends that all nodes on the network be
assigned the same domain and organization.
Assign meaningful node names. For example,
MKTG.BND.HP and LAB.BND.HP are meaningful names
for two nodes on the same network within
Hewlett-Packard. One node (MKTG.BND.HP) is
used by the marketing department. The other
node (LAB.BND.HP) is used by the lab. The
domain field is the same because the nodes
belong to the same network. The organization
field is the same because the nodes belong to
the same internetwork.
Are you using OpenView If you answer yes to this question, NMMGR
DTC Manager? assumes you are using a PC to manage your
system and takes you to the corresponding set
of screens when you configure DTS. If you
answer no, NMMGR assumes you are using
host-based network management and takes you to
a different set of DTS screens. You should
already have answered this question when you
configured DTS.
Do you have X.25 If you answer yes to this question, NMMGR
system-to-system or PAD assumes you are configuring X.25 connections
connections? and takes you to the set of screens required to
configure DTC X.25 Network Access Cards when
you configure DTS. If you answer no, NMMGR
assumes you have no need to configure X.25
connections and takes you to a different set of
DTS screens. You should already have answered
this question when you configured DTS.
To Select Guided Configuration
The NS Configuration screen (#166) in figure 5-4is displayed if you press
the [NS] key at the Main screen (#2) in figure 5-3.
Figure 5-4. NS Configuration Screen
Steps.
1. If you are using domain names for network access, replace the node
name in the field at the bottom of the screen with this system's
domain name and press the [Save Data] key. If not using domain
names, leave the node name as is.
2. Press the [Guided Config] key to proceed with guided configuration
of LAN.
Guided/Unguided Configuration
Hewlett-Packard recommends that you press the [Guided Config] key to
select the guided configuration branch whenever you need to initially
configure a network interface. Guided configuration supplies many
default values for your configuration and requires that you visit a
minimal number of screens. This manual provides information on every
screen available to you through unguided NS configuration.
The [Unguided Config] key is used to modify configuration values that are
not available in the guided screens. To use the unguided configuration
screens, refer to the NS3000/iX NMMGR Screens Reference Manual.
Fields.
Local Domain Name The name of this system in the ARPANET standard
format. This name can be used by other nodes on the
network to access this host.
The domain name is composed of labels, with each
label separated by a period. Each label must start
with a letter or digit, and have as interior
characters only letters, digits, hyphens (-), or
underbars (_). A domain name may have any number of
labels, but its total length, including periods, is
limited to 255 characters.
label[.label][...]
Domain names are not case sensitive.
Use of domain names is optional. If you are not
using domain names for network access, leave the
local node name in this field.
To Perform Guided Network Transport Configuration
The Network Transport Configuration screen (#42) in figure 5-5 is
displayed if you press the [Guided Config] key at the NS Configuration
screen (#166) in figure 5-4.
Figure 5-5. Network Transport Configuration Screen
Steps.
1. Next to the words Enter a network interface:, enter a name for the
selected network interface (for example, LANNI).
2. Next to the words Enter a network type:, enter the selected
network type number indicated on the above screen. (For example,
enter a 1 to indicate that the NI is a LAN NI.)
3. Press the [Config Network] key. (There may be a short pause
before the next screen appears.)
4. Proceed to the chapter of the network interface selected above for
screen information. Refer to chapter 6 for information on LAN,
token ring, and FDDI; and chapters 7, 8, and 9 for information on
point-to-point, X.25, and Gateway Half respectively.
NOTE NS/SNA is no longer offered as a product and has been removed from
the Corporate Price List. The product is obsolete with no plans
for support.
Fields.
Enter a network The network name (NI name) is used to easily identify
interface one of the types of network interfaces: X.25, LAN,
FDDI, point-to-point (router), gateway half, SNA, or
token ring. The name can be up to eight alphanumeric
characters, starting with a letter. The maximum
number of NIs that can be configured on a node is 12.
One of the 12 allowable NIs is reserved for loopback.
(Loopback is configured for you automatically.)
If a node interfaces to more than one network, give
each NI on that node a unique name. Although all
nodes on the same network do not have to have the
same
NI name, it will be easier to remember if you make
the NI name the same for all nodes on the same
network (for instance, LANNET). You will use the NI
name with the NETCONTROL command to start the
transport and network link.
Enter a network Number that indicates the type of network interface
type you are configuring. You must enter a network type
if you are configuring a new network interface.
Enter 1 for a LAN NI, 2 for a point-to-point (router)
NI, 3 for an X.25 NI, 4 for an SNA NI, 5 for a
gateway half NI, 6 for a token ring NI, or 7 for an
FDDI NI.
