Using the Node Management Services (NMS) Utilities: HP 3000 MPE/iX Computer Systems > Chapter 3 Using NMMGR in Screen Mode![]() Selecting a Configuration Path |
|
Once a configuration file is successfully opened or created, NMMGR displays the Main screen, shown in Figure 3-2 “Main Screen”. This screen presents a menu from which you select the group of NMMGR screens you need to configure the appropriate subsystem.
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:
Each of the configuration subbranches are described. Terminals, printers, and other serial devices are connected to HP 3000 Series 900 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 “Host Configuration Screen”), 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. You will perform a number of tasks using these screens, including the following:
See the following manuals for more information on configuring DTCs and serial devices:
The NS 3000/iX product consists of NS 3000/iX Network Services and NS 3000/iX links. NS 3000/iX Network Services contain software that allows you to access data, initiate processes, and exchange information between all the systems on a network. NS 3000/iX links provide connections between systems (either HP 3000s or personal computers) in a network. To use NS 3000/iX Network Services, the systems must be connected by an NS 3000/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 “NS Configuration Screen”), the first screen in a progression that lets you configure NS. 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.)
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 “Network Transport Configuration Screen”. 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. 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.
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 “Unguided Configuration Screen”. From this screen, you can move to the screens that let you:
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 NS 3000/iX Screens Reference Manual for information on the unguided NS configuration screens. Hewlett-Packard provides a number of networking products that make it possible to establish communication links between HP 3000 Series 900 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 “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. |
