Automatic configuration can also be performed by invoking the DTCCNTRL command file inside the NMMGR utility. Refer to Chapter 5 “Configuring Serial Devices (for Host-Based Management)” for detailed steps on the NMMGR DTS host-based management configuration process. To automatically add and configure a DTC within NMMGR, you must still provide the DTC's LAN address. Also, as with performing an automatic configuration outside NMMGR, all serial ports using DTCCNTRL will be configured as nailed, direct connect terminal ports using the terminal profile TR10AUTO.

NOTE: You can only perform automatic configuration of new DTCs if you are operating in a host-based management environment. In a PC-based management environment, NMMGR will report an error if the automatic configuration is invoked.

Step 1: Use Valid Configuration File

You must first already have a valid network configuration file and your HP 3000 must not have experienced any Datacommunication Configurator (DCC) errors during the last reboot. Refer to Appendix D “Error Messages” for more information on DCC error messages.

Step 2: Activate Automatic Configuration Process

The DTC Configuration Selection Screen (Figure 3-1 “DTC Configuration Selection Screen”) is displayed when you press the [Go to DTC] key at the Host Configuration Screen. Here you can access the DTC Automatic Configuration Screen and activate the automatic configuration process.

DTC Configuration Selection Screen

Follow the steps listed here to enter data for this screen.

  1. In the "Automatically add/configure a new DTC (Y/N)?" field, enter a Y and press the [Enter] key.

  2. The DTC Automatic Configuration Screen will appear.

Step 3: Complete Automatic configuration

The DTC Automatic Configuration Screen appears (Figure 3-2 “The DTC Automatic Configuration Screen”).

Follow the steps listed here.

  1. Make sure that the power for the DTC that you want to automatically add and configure is turned on.

  2. Enter the LAN address of the DTC to be configured in the "DTC LAN station address" field. The LAN address can be found on a label inside the front cover or on the back panel of the actual DTC box. Note that the LAN address is different from the IP address which is discussed in step 4 below.

  3. (Optional) Enter the DTC node name in the format node.domain.organization in the "DTC node name" field. If you leave this field blank, a default DTC node name will be created. The default node name created will be DTCxxxx.domain.organization, where xxxx are the last four digits of the DTC's LAN address and domain.organization are taken from the host's node name.

  4. (Optional) Enter the DTC IP address in the "DTC IP Address" field. The IP address is used if your HP 3000 is configured as part of a network and you want the DTC to be able to respond to PING/iX requests.

  5. Press the [Auto Config] function key to invoke DTCCNTRL and start the automatic configuration process.

  6. The following will appear on the screen indicating successful DTC automatic configuration:

    DTCxxxx.domain.organization automatic configuration in progress.....

    (DTC download messages will appear here if you are at the system console.)

    DTCxxxx.domain.organization configured and downloaded successfully.

    All ports configured successfully.

    (Press RETURN when done viewing screen contents)

  7. Press the [Return] key when you have finished viewing the automatic configuration messages. You will return to the DTC Automatic Configuration screen.

    When automatic configuration is complete, a default configuration is created in the NMCONFIG.PUB.SYS file. The default configuration will be saved with DTC name as DTCxxxx where "xxxx" is the last 4 digits on the LAN address.

  8. You may automatically configure other DTCs from this screen by repeating steps 1 through 7 for each DTC. If you have automatically configured all desired DTCs, proceed to step 9.

  9. Press [Prior Screen] to return to the DTC Configuration Selection screen. From here, you may continue with other DTS configuration changes (refer to Chapter 5 “Configuring Serial Devices (for Host-Based Management)” for steps on how to do this) or exit NMMGR. If you decide to exit and have already completed other DTS configuration changes in addition to an automatic DTC configuration, you must first validate and cross-validate your configuration file. Otherwise, you may simply exit NMMGR.
