Using the Node Management Services (NMS) Utilities

Selecting a Configuration Path 

Once a configuration file is successfully opened or created, NMMGR
displays the Main screen, shown in figure 3-2.  This screen presents a
menu from which you select the group of NMMGR screens you need to
configure the appropriate subsystem.


          Figure 3-2.  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  The product is obsolete with no plans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.


The main screen also contains three data fields that you must complete in
order to configure the local node name and determine which type of
network configuration is appropriate for the node.

The following steps describe the action you should take at the Main
screen:

   1.  Enter the node name of the system you are configuring in the local
       node name field (if it is not already present).

   2.  In the field next to the question Are you using OpenView DTC
       Manager?, enter a "Y" if you are using PC-based network management
       for this node, enter an "N" if you are using host-based network
       management.  If you are using PC-based network management, an
       OpenView workstation must be present on the network.

   3.  In the field next to the question Do you have X.25
       system-to-system or PAD connections?, enter a "Y" to indicate you
       will be configuring a DTC/X.25 Network Access card for this node,
       otherwise, enter an "N".

   4.  Press the [Save Data] key to save the node name in the
       configuration file (create the data record).  The Data flag will
       be set to "Y" when the data record exists.

   5.  Proceed to one of the NMMGR configuration subbranches by pressing
       the appropriate function key.

Each of the configuration subbranches is described below.

Configuring Terminals, Printers, and Other Serial Devices 

Terminals, printers, and other serial devices are connected to 900 Series
HP 3000 computers through a device called the Datacommunications and
Terminal Controller (DTC). In order to connect to a device, the system's
configuration file must contain information that makes it possible for
the DTC, as well as the devices attached to the DTC, to establish
communications with the system.  DTCs and their devices are configured
through NMMGR's distributed terminal subsystem (DTS) configuration.

If you press the key labeled [DTS] at the Main screen, you will be taken
to the Host Configuration screen (figure 3-3), the first screen in a
progression that lets you configure DTS for PC-based network management
only.  The Host-based management screen will vary slightly.


          Figure 3-3.  Host Configuration Screen 

You will perform a number of tasks using these screens, including the
following:

   *   Define the DTS link configuration for the system.

   *   Define connection capabilities for terminals, printers, and other
       serial devices that will be able to communicate with the system.

   *   Define terminal, printer, and other serial device profiles
       specifying sets of characteristics that can be applied to various
       terminals, printers, or other serial devices connected to the
       system and associate the profiles with individual devices.  The
       screen in figure 3-3 reflects PC-based network management only.
       The Host-based management screen will vary slightly.

See the following manuals for more information on configuring DTCs and
serial devices:

   *   Configuring Systems for Terminals, Printers, and Other Serial 
       Devices.

   *   (Host-based X.25 configuration only) Configuring and Managing 
       Host-Based X.25 Links.

   *   (PC-based configuration only) Using the OpenView DTC Manager.

Configuring NS3000/iX 

The NS3000/iX product consists of NS3000/iX Network Services and
NS3000/iX links.  NS3000/iX Network Services contain software that allows
you to access data, initiate processes, and exchange information between
all the systems on a network.  NS3000/iX links provide connections
between systems (either HP 3000s or personal computers) in a network.  To
use NS3000/iX Network Services, the systems must be connected by an
NS3000/iX link and each link must be properly configured through NMMGR.

If you press the key labeled [NS] at the Main screen, you are taken to
the NS Configuration screen (figure 3-4), the first screen in a
progression that lets you configure NS.


          Figure 3-4.  NS Configuration Screen 

NMMGR provides two methods of creating or updating configuration
information for an NS link.  The methods are referred to as guided HP
configuration and unguided HP configuration respectively.  You determine
which method you will use by making a choice at the NS Configuration
screen.

You also use this screen to configure a domain name for the node you are
configuring if using domain names for network access.  To configure a
domain name, replace the local node name in the field at the bottom of
the screen and press the [Save Data] key.  (If you are not using domain
names, leave the local node name as is.)

   *   To perform guided configuration, press the key labeled [Guided
       Config] and refer to the HP 3000/iX Network Planning and 
       Configuration Guide for information.

   *   To perform unguided (manual) configuration, press the key labeled
       Unguided Config and refer to the NS3000/iX NMMGR Screens Reference 
       Manual for information.


NOTE  Hewlett-Packard strongly recommends using guided configuration
      whenever you need to initially configure a network interface.  You
      can also take advantage of its convenience later for most network
      maintenance and updating.  Guided configuration supplies many
      default values for your configuration and requires that you visit a
      minimal number of screens.  Use unguided configuration only if you
      need to modify configuration values that are not available on the
      guided screens.


Guided HP Configuration.   

If you press the key labeled [Guided Config] at the NS Configuration
screen, you will be taken to the Network Transport Configuration screen
shown in figure 3-5.  From this screen, you choose the specific task you
want to perform using guided NS configuration.  These tasks include
configuring or modifying a network interface, modifying logging
parameters, and fine tuning global or network transport configuration
parameters.


          Figure 3-5.  Network Transport Configuration Screen 

Guided configuration is a procedure that automates part of the
configuration process.  It "guides" you through the configuration screens
for a specific task.  It assumes and supplies default values wherever
possible to furnish most of the configuration file's data.

When you run guided configuration, you use only a minimal number of
configuration screens.  You will normally use fewer screens than you
would if you were performing the same task using unguided configuration.
Many of these screens are different from those used for unguided
configuration.


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.


Unguided Configuration.   

If you press the key labeled [Unguided Config] at the NS Configuration
screen (#166), you will be taken to the Unguided Configuration screen
shown in figure 3-6.


          Figure 3-6.  Unguided Configuration Screen 

From this screen, you can move to the screens that let you:

   *   Configure or modify a network interface.

   *   Configure or modify an NS link.

   *   Configure or modify logging parameters.

   *   Configure or modify a network interface.

If you choose to create or modify an NS configuration using unguided
(manual) configuration, you must take care that you know which screens
you need to use to completely create or modify a configuration.  The
unguided nature of manual configuration makes it possible to get "lost"
or to miss some necessary screens entirely.

Under most circumstances, HP recommends that you use guided
configuration.  Unguided configuration can be useful, however, if you
only need to use a few screens and you know exactly which screens you
need.

Refer to the NS3000/iX Screens Reference Manual for information on the
unguided NS configuration screens.

Configuring HP-IBM Connections 

Hewlett-Packard provides a number of networking products that make it
possible to establish communication links between 900 Series HP 3000s and
IBM mainframe computers.

If you press the key labeled IBM at the Main screen, you are sent to the
HP-IBM Configuration screen shown in figure 3-7.


          Figure 3-7.  HP-IBM Configuration Screen 

From this screen, you can choose any of the IBM subsystems for
configuration by pressing the appropriate function key.  You can also
choose to configure logging for all of the IBM subsystems, or you can
choose SNANODE configuration (SNA node, SDLC link, X.25 link, and token
ring link).

The HP-IBM Configuration screen presents you with more choices than there
are available function keys.  For this reason, the screen includes a Next
Key Labels function key that lets you toggle between two sets of function
key choices.  If the choice you want does not currently appear on any of
the "Go to" function keys, press the [Next Key Labels] key.  You can then
make the choice you need to configure the HP-IBM subsystem you want to
configure.

For more information on configuring any of the HP-IBM products, see the
Node Manager's Guide for that product.  For information on HP-IBM
subsystem logging or SNANODE configuration, see the SNA Link/iX Node 
Manager's Guide.
