1 Introduction to DTC Manager/UX This chapter describes the DTC Manager/UX software and the types of DTCs it can manage. The DTC Manager/UX software provides management functions for Data Communications Terminal Controllers (DTCs) that enable you to create and maintain DTC configuration files. The DTC Manager/UX runs on the HP 9000 Series 7001 and 800 computer systems. The HP 9000 system is called the host system.
1 DTC Manager/UX overview As a LAN-based communications controller, each DTC can be located wherever it is most convenient for you. You may choose to locate DTCs close to the devices they control. Alternatively, you may locate them some distance away from the computer systems to which they provide access. The design of the DTC enables you to tailor your physical layout to your own needs. The maximum number of ports available on a DTC depends on the DTC type and the combination of boards installed in it.
DTC Manager/UX overview DTC Manager/UX commands Note All DTC Manager/UX commands require superuser privileges.
1 DTC Manager/UX overview Required daemons The following daemons must be running on the HP 9000 host computer for the configuration information to be downloaded to the DTC. Note These daemons must be run with superuser privileges. • rbootd—remote boot server daemon • dtcnmd—DTC network management daemon • dtcnmp—DTC state machine daemon The rbootd daemon waits for a boot request packet from the DTC.
DTC Manager/UX overview DTC 16 The DTC 16 can be fitted with two boards of eight ports, giving a maximum of 16 ports. It can provide connections for up to 16 directly-connected devices, or 12 remote devices using modems, or a combination of both. The back of the DTC 16 actually has three slots; two slots for connector cards and one empty slot. DTC 48 The DTC 48 can be fitted with six boards of eight ports, giving a maximum of 48 ports.
1 IP addresses IP addresses IP (Internet Protocol) addresses are composed of 32-bit integers and are used to identify an IP node in the Internet. An IP address can be assigned to a DTC as well as to an individual port on a DTC. IP addresses are usually represented in the following form: x.x.x.x where x is a decimal number in the range 0 to 255. Be sure that you: • Assign a unique IP address to each IP node in your network • Do not assign network addresses or node addresses that are all 1s or all 0s.
Special DTC terminology Special DTC terminology The following specialized terms are used in this manual. Board and card The terms board and card are used in this manual to mean the same thing. For the DTC 16 and DTC 48, the term card is employed, for example, SIC (Serial Interface Card) or connector card. The DTC 72MX and, in general, all other DTC types now use the term board. CPU/LAN or LAN processor board Each DTC has a processor board that handles the overall management of the DTC.

2 Before installing DTC Manager/UX This chapter describes requirements that must be satisfied before DTC Manager/UX can be installed. Even though the product supports up to 4 LAN devices, it is recommended that all LAN devices be located on a single LAN, lan0 (to facilitate the installation procedure), and that DTC Manager/UX be located on this same LAN. DTC Manager/UX is, however, compatible with other LAN devices that are connected to the LAN by means of a bridge or hub.
2 Note This note only applies to DTC 48s and DTC 16s. DTC 48s with a date code less than 3110 require a memory extension and must be upgraded with the DTC 48 Upgrade Kit (HP product 2348A). DTC 48s with a date code of 3110 or later and DTC 16s do not require a hardware memory extension. Note The following DTC-installable cards are not supported on a DTC being managed on an HP 9000 system by the DTC Manager/UX software: - X.25 Synchronous Network Processor card - Telnet Access Card.
3 Installing DTC Manager/UX This chapter describes how to install DTC Manager/UX software and prepare the environment for the required daemon processes. Instructions are provided for HP-UX 10.x and HP-UX 9.x. It is presumed that the HP-UX operating system, LAN/9000, and Internet Services are installed and operational on your site. Installation considerations You can install the DTC Manager on an upgraded HP-UX 10.x system in much the same way as if you were installing from scratch.
3 Installing DTC Manager/UX with HP-UX 10.x Installing DTC Manager/UX with HP-UX 10.x You install DTC Manager/UX software with the swinstall utility program. Refer to the man pages for instructions on how to use swinstall. HP software is delivered in bundle form (bundles contain one or more software products, subproducts and related filesets). The name of the DTC Manager/UX bundle is J2120A.
Installing DTC Manager/UX with HP-UX 10.x 6 Use the space bar (or mouse) to highlight the product and then select Mark For Install from the Actions menu. A screen appears with information about various dependencies required for the operation of DTC Manager/UX. 7 Select OK. Yes appears to the left of the product name. 8 Select Install (analysis)... from the Actions menu. The Install Analysis screen appears.
3 Installing DTC Manager/UX with HP-UX 10.x Preparing the environment for the required daemon processes Before you can run DTC Manager/UX, you must configure certain parameters in the /etc/rc.config.d/netdaemons file. This is necessary to ensure that the required daemons will be started automatically when your system is rebooted. Checking the name of LAN device file 1 Execute the lanscan command to display the list of physically connected LAN devices on your system.
Installing DTC Manager/UX with HP-UX 10.x Note Quotation marks are mandatory if you are declaring more than one device and a space is not allowed after the equal (=) sign. Caution Do not remove any existing LAN device declarations from this line. This information might be needed for other system functions. 3 Save the file (if you made any modifications) and exit the editor. Running the daemons without rebooting DTC Manager/UX cannot run without the required daemon processes.
3 Installing DTC Manager/UX with HP-UX 10.x Verifying that the daemons are running 1 Use the ps -ef command to check the daemons. To check whether rbootd is running, use: ps -ef |grep rbootd To check whether dtcnmd and dtcnmp are running, use: ps -ef |grep dtcnm 2 Look at the rbootd and dtcnmd log files to check for errors when the daemons were started up. Execute the HP-UX tail command from the shell prompt to look at the log files. Make sure that the tail command shows enough information.
Installing DTC Manager/UX with HP-UX 10.x Note The following commands are for HP-UX version 10.30 (with four lan cards; lan0, lan1, lan2 and lan3): tail /var/adm/rbootd.
3 Installing DTC Manager/UX with HP-UX 10.x Verifying the software version At the prompt, type the following command: what /opt/dtcmgr/sbin/dtcdiag You will see a line similar to the following which will show your software version: DTC Manager/UX: Revision A.14.4A.030 copyright ... software version If you don’t want DTC Manager to be started automatically DTC Manager is automatically started by default when your system reboots. You may want to disable this feature (for troubleshooting for example).
Installing DTC Manager/UX with HP-UX 9.x Installing DTC Manager/UX with HP-UX 9.x The DTC Manager/UX software is installed using the update command on systems running HP-UX 9.x. The update command is described in the manual Installing and Updating HP-UX. Installing the software 1 Ensure that you are logged in as root and that you are at the root directory. 2 Ensure that your fileset version matches the version of your HP-UX operating system.
3 Installing DTC Manager/UX with HP-UX 9.x Verifying the installation 1 After update has terminated, check that the installation was successful. Execute either the HP-UX more command or the tail command to look at the file /tmp/update.log. The file /tmp/update.log file contains the installation status (successful or unsuccessful). If you use the tail command make sure enough of the file is displayed for you to see the status. more /tmp/update.log or tail /tmp/update.
Installing DTC Manager/UX with HP-UX 9.x However, if your LAN device file name is not /dev/lan0, you must start the daemons manually and edit the file /etc/rc yourself. The steps below describe how to check the LAN device file name. 1 Execute the lanscan command to display the list of physically connected LAN devices on your system. 2 Look for the Net-Interface Name defined in the information displayed by lanscan.
3 Installing DTC Manager/UX with HP-UX 9.x 1 Start the rbootd and dtcnmd daemons manually by typing the following commands at the shell prompt: /etc/rbootd landevice /etc/dtcnmd landevice The landevice is the LAN device file name that you found on page 35 in step 2. It is the LAN interface card that connects your HP 9000 to the LAN. This is the same LAN that the DTCs are on.
Installing DTC Manager/UX with HP-UX 9.x 2 Look at the rbootd and dtcnmd log files to check for errors when the daemons were started up. Execute the HP-UX tail command from the shell prompt to look at the log files. Make sure that the tail command shows enough information. tail /usr/adm/rbootd.log Tue Sep 10 14:00:23 1992 pid=1234: STARTUP Tue Sep 10 14:00:23 1992 pid=1234: INITIALIZATION COMPLETE tail /usr/adm/dtcnmd.
3 Managing DTC configuration files Managing DTC configuration files The following section contain information on how to manage DTC configuration files. Automatic protection of configuration files An automatic lock feature protects the integrity of the DTCs new data. The lock mechanism becomes effective when you run update in HP-UX 9.x, swinstall in HP-UX 10.x, or when a new DTC is added. All DTCs remain operational.
4 Using dtcconfig This chapter provides information about the DTC configuration procedure and describes the basic use of the menu-driven configuration utility dtcconfig. The following dtcconfig operations are covered: • running dtcconfig • choosing a menu item from the DTC Configuration Main Menu • entering values at the DTC configuration menus • using the DTC configuration function keys • using the shell function key • getting help • exiting from a task or from dtcconfig.
4 When the DTC is switched on, it is configured with: • information that the DTC sends to the manager (such as the number of boards) • user-defined settings • and other parameters such as the DTC IP address that you enter when you add a new DTC to the configuration. In most cases you can successfully configure your DTCs with information contained in chapter 5. This will enable you to connect terminals to your DTCs.
To start the dtcconfig utility To start the dtcconfig utility Once you have installed the DTC Manager/UX you are ready to configure your DTC. Note The dtcconfig command requires superuser privileges. Make sure you logon as root or type the HP-UX su (superuser) command.
4 Using the dtcconfig menus Using the dtcconfig menus The DTC configuration tool (dtcconfig) provides menus, fields, and function keys to help you configure your DTC devices. It has three types of menus: • Main menu: used to access other menus and functions. • Actions menu: provides you with a selection of possible actions you can take from the current screen. • Data acquisition menu: provides you with a list of possible field values. This menu is displayed by pressing the Help (F1) function key.

The following keys have specific functions: (F1)–Help: used to obtain a summary of information for a particular field or menu item.
Using the editing keys Using the editing keys You use the dtcconfig editing keys to enter values in the various fields. You should note that some of the editing keys do not function as they normally would if you were editing text. Specifically, the following keys behave differently: • [Clear Line]—If you use this key while entering a value in a field, you do not get a response. The line is not cleared and you must return to the beginning of the field to start entering the value again.
4 Getting help Getting help There are three areas of online help: • The Help for Using DTCconfig menu item from the main menu. Selecting this menu item displays general dtcconfig help information. This is an overview of the dtcconfig screens and the keyboard keys. • Help (F1) function key. Almost all dtcconfig screens include a Help function key. Pressing this function key provides information about the field you are currently in. • List of DTCs.
5 Adding DTCs This chapter describes how to add one or more DTCs to the set of DTCs managed by DTC Manager/UX. Note 150 is the maximum number of manageable DTCs. Note The instructions in this chapter presume that DTC Manager/UX is already properly installed and that you are familiar with the basic use of the dtcconfig menus and function keys as described in chapter 4.

8 Configuring DTC ports with dtcconfig This chapter describes how to configure a port for the requirements of an attached device. For example, if you want a printer on a certain port, you must ensure that the port is set to be a printer port. Configuring the port type You can change a terminal port to a printer port (or vice versa) using the Change Port Type option which you access via the Action Menu as illustrated below.
8 Configuring the port type The steps are as follows: 1 Enter the board and port numbers at the Rear Panel Configuration screen. 2 Press the Action Menu (F5) function key and select Change Port Type. The Change Port Type screen appears. 3 Note Indicate a printer or terminal port type by entering an x or X in the appropriate field and press Return or the Done (F4) function key. Change Port Type copies in the default port settings for the specified port type (terminal or printer) when it is used.
Configuring terminal and printer ports Configuring terminal and printer ports Once a port has been configured, this configuration can be copied and pasted to other ports as described in chapter 9. To modify several DTCs simultaneously, use the dtcmodifyconfs command as described in chapter 10. Note For the purposes of the procedures described in this chapter it is presumed that you have added at least one DTC to the configuration and that it has at least one board in it.
8 Configurable port parameters Configurable port parameters The following port attributes are covered in this chapter. • • 88 Port Parameters are listed below and explained in the section see “Configuring terminal and printer port parameters” on page 91. • Terminal or Printer Name or IP address • Line Speed • Attached Device • Bits Parity (called “Parity” in version A.14.29) • Number of Stop Bits (applies to version A.14.

11 Resetting DTC configurations This chapter provides information about when and how to reset DTC configurations. DTC configurations are reset whenever the configuration information is downloaded to the DTC (each time the DTC is rebooted, for example). Topics covered include: • when you need to download the DTCs configuration • why you sometimes need to download the DTC's configuration from the DTC Manager/UX to the DTC • how to download the DTCs configuration.
11 Why downloading is necessary Why downloading is necessary The firmware of the DTC contains only the code for self-test, self-diagnostics, and download protocol. Most of the DTCs operational software must be loaded when the DTC is powered-up through a process referred to as software download. The software code to be downloaded to each DTC resides permanently on the computer that is responsible for managing and controlling the operations of that DTC.
Downloading the configuration Resetting a DTC Board To reset a DTC board, use the command: dtcreset dtcname board_number Resetting a DTC Port To reset a DTC port, use the command: dtcreset dtcname board_number port_number 139 11

12 Configuring DTC Manager for operation with MC/ServiceGuard MC/ServiceGuard ensures non-interrupted operation or “high availability” for DTC Manager/UX by providing the capability to transfer DTC management to another HP 9000 host (node) in the event of system failure. MC/ServiceGuard manages a “package” of applications that can be relocated to another node within an MC/ServiceGuard cluster.
12 Note DTC Manager/UX communications cannot be transferred to a backup LAN although this is supported by MC/ServiceGuard for other applications. High availability for DTC Manager/UX is provided only by MC/ServiceGuard’s node transfer capability. Refer to Managing MC/ServiceGuard (part number B3832-90001) for information specific to cluster management and highly-available computer systems.
Prerequisites Prerequisites Before you continue with the procedures described in this chapter, verify that your site satisfies the following requirements: • MC/ServiceGuard must be installed at your site (see the MC/ServiceGuard documentation) • DTC Manager/UX software must be properly installed and configured on the original host system and all potential, “adoptive”, host systems (see chapter 3) • the required daemon processes must be properly configured and operational (i.e.
12 Transferring DTC configurations to an adoptive host 2 Execute the following command for each connected DTC: dtcexport dtcname This exports the DTC configuration to the /var/opt/dtcmgr/dtcname.exim (default) file. Example To export the configuration of dtc1 to the file dtc1.exim you would enter: dtcexport dtc1 3 Disown all DTCs connected to the original host by entering: dtcdisown dtcname for each connected DTC.
Transferring DTC configurations to an adoptive host Copying the configuration files to the adoptive host Use ftp (in binary mode) to copy the configuration (dtcname.exim) files to the /var/opt/dtcmgr directory on the adoptive host system.
12 Configuring other adoptive hosts On the adoptive host 1 Own all DTCs that will belong to this host in the event of original host failure. dtcown dtcname 2 Reboot all DTCs by switching them off and then on. 3 Check that each DTC is operational by executing a command such as dtcping dtcname to verify that each DTC can be managed on this node. 4 Disown all DTCs belonging to the adoptive host by entering: dtcdisown dtcname for each DTC. This is a precaution to avoid possible conflicts of ownership.
Including DTC Manager/UX in a high-availability package Including DTC Manager/UX in a high-availability package You can now include DTC Manager/UX in an MC/ServiceGuard package by following the instructions below. On the original host 1 Follow the instructions in the MC/ServiceGuard documentation to generate and then modify a package configuration file template. 2 For MC/ServiceGuard to work with DTC Manager/UX, you must edit the package control script, control.
12 Future configurations Future configurations When you modify DTCs Each time you modify the configuration of a DTC you must: 1 Create a new export file on the original host using the dtcexport command. 2 Copy the file to each potential adoptive host. 3 Import the file to each adoptive host using the dtcimport command. When you add new DTCs Each time you add a DTC to your configuration you must: Note 1 Create a new export file on the original host using the dtcexport command.
13 Diagnosing problems with dtcdiag, dtcping and dtccheckip This chapter explains the use of three troubleshooting tools: dtcdiag, dtcping and dtccheckip. The dtcdiag command reports DTC diagnostic information and can perform diagnostic tasks on a DTC, on a DTC board, or on a selected port of a board.
13 About dtcdiag About dtcdiag The following commands can substitute for dtcdiag command options: • dtcconnstat—obtains the status from selected ports • dtcdownload—downloads EEPROM code to a LAN board1 • dtcquickswitch—switches DTC management from one host to another • dtcreset—resets a DTC, board, or port • dtcstat—obtains the status of a DTC • dtctest—tests a CPU/LAN board, or selected port • dtctraceon—turns on extended trace on selected ports1 • dtctraceoff—turns off extended trace on
About dtcdiag Note Once you have executed dtcdiag, you cannot stop it. You can kill the dtcdiag process, but you cannot stop the operation from completing. The dtcdiag command completes execution on a DTC even if it is killed (by using CTRL-C) before it is able to report the completion status. The dtcnmp process continues the execution of the dtcdiag command. You can only run one of the following commands at a time: dtcdiag (or synonym), dtcconfig, dtcmodifyconfs (or synonym), or dtcping.

Using dtcdiag Using dtcdiag Resetting DTCs, boards and ports The dtcdiag command can be used to reset a DTC, board or port. Use the command: dtcdiag -r or dtcreset Note The board in the DTC 16TN cannot be reset. You can only reset the entire DTC or a single port.
13 Using dtcdiag Running loopback tests The following commands and options can be used to perform loopback tests. dtcdiag -i [count] or dtctest -i [count] Performs an internal loopback test on the selected ports count times. dtcdiag -h [count ] or dtctest -h [count ] Tests the data path through a DTC 48 (or a DTC 16) to the serial port and through the serial port connector. A loopback hood must be attached to the port. This option does not apply to other DTC types.
Using dtcdiag dtcdiag -S or dtcconnstat Obtains the status of the connections from the selected ports and lists it to the standard output.
13 Special Commands (use only when instructed by an HP engineer) Special Commands (use only when instructed by an HP engineer) This section describes commands that an HP engineer might ask you to run. Caution Only use the following commands if instructed to do so by an HP engineer for troubleshooting purposes. The information uploaded to the DTC Manager/UX during a DTC upload can only be read with special formatting tools available only to HP engineers.
Special Commands (use only when instructed by an HP engineer) Uploading files from a DTC dtcdiag -u or dtcupload Uploads the selected objects. Only a DTC 72MX can have a 24 port MUX board upload performed on it. The following upload data files are created: /var/opt/dtcmgr/upload/dtc.Bx Contains upload data files from the CPU/LAN or the LAN of a DTC, where x is cycled from 1 to 3 (and then back to 1) for each new upload. /var/opt/dtcmgr/upload/dtc.
13 Other dtcdiag parameter definitions Downloading the EEPROM code to a LAN board Caution Downloading EEPROMs incorrectly can make your DTC unusable. Only download EEPROMs if told to do so by an HP engineer. dtcdiag -d or dtcdownload Downloads the EEPROM (Electrically Erasable Programmable Read-Only Memory) code for the selected LAN boards. Only a DTC 72MX or a DTC 16TN can have an EEPROM code download performed on them.
Other dtcdiag parameter definitions -l loglevel Specifies the amount of information that is logged in the log file for this dtcdiag execution. The default logfile is /var/opt/dtcmgr/log/dtcdiag.log. Specify one of the following logging levels: 0 1 2 -L logfile Log only startup and termination messages. Log serious or fatal error messages (and those of level 0). This is the default. Log warning and informational messages (plus the messages of level 1).
13 Other dtcdiag parameter definitions B or b all ports on a DTC 16TN (a DTC 16TN does not have a separate board) 0 ... 5 the boards on a DTC 48 0,1 the boards on a DTC 16 0 ... 3 for the boards or LAN board on a DTC 72MX. The asterisk metacharacter (*) can be used to represent all non-CPU/LAN or nonLAN boards on a DTC and it normally needs to be escaped.
About dtcping About dtcping The dtcping command is used as a troubleshooting tool to perform a connection test. dtcping is similar to the networking ping command (refer to the online man page for ping). The ping command sends a series of packets to a remote node which are echoed back. The dtcping command sends a series of packets to the DTC which are echoed back. Both commands are useful to check if a DTC is still up and running at least at the IP level of the networking stack.
13 About dtcping numpackets The number of packets dtcping transmits before terminating. The minimum value allowed for numpackets is one and the maximum is 999. Numpackets defaults to one if it is not specified. Examples Send 10 packets to dtc01: dtcping dtc01 -n 10 Perform dtcping on all DTCs and send a packet size of eight bytes: dtcping \* 8 Values returned by dtcping One of the following values is returned when dtcping is executed.
About dtccheckip About dtccheckip The dtccheckip command is used as a troubleshooting tool to check for duplicated IP addresses. If you have added a DTC or modified information about LAN address configuration, dtccheckip is automatically run after the termination of dtcconfig. When the Exit DTCconf function key is pressed in the dtcconfig menu, you are asked whether you want to quit or not. If you reply “yes”, this ends the execution of the dtcconfig command and executes the dtccheckip command.
13 About dtccheckip 164
14 Listing configurations and events with dtclist This chapter describes the syntax and use of the dtclist command which enables you to display data in the configuration and event log files. The dtclist command can display one of the following: • A summary of configuration data for a DTC. This can include information about the CPU/LAN or LAN, backplane, boards, and ports. • A list of the user DTC default configurations. • A list of events that are placed in the event log.
14 Using dtclist Using dtclist 1 Logon as root or type the HP-UX su (superuser) command from the shell prompt. 2 At the shell prompt, specify one of the following dtclist commands. To display a summary of configuration data for a DTC, run the following command. The output can contain information about the CPU/LAN or LAN, the boards and the ports. dtclist -c [logging] [object] To list the DTC user default configuration, run the following command.
Using dtclist Parameter definitions -c Lists the DTC configurations. If object is not specified, then the list of DTCs managed by the host computer is displayed. -C Lists the DTC user default configuration. logging The dtclist command supports the following logging options. -a Appends the log messages from the dtclist command to the existing dtclist log file. By default, the existing log file is overwritten. The default log file is /var/opt/dtcmgr/event.log.
14 Using dtclist filter -e [start end] The filter parameters specify the type of events to be listed: The range of events in the event log to be listed with these optional parameters. If no range is given, all events are listed. To specify the last event of the event log, use the notation $ or e. To specify an event relative to the last event of the event log, use the options $-n or e-n, where n is the number of events from the last event.
Using dtclist -t range -f object Specifies the range of dates and times to be displayed. The dates are in a free format, such as month-day-year all in numbers or in words. For example, 8 Apr 1997 and Wed Apr 9 1997 are two ways to specify the same date. Quotation marks (") are used to delimit a range. date1
14 Using dtclist 0 or 1 board number for a DTC 16 0 ... 3 board number for a DTC 72MX The number of the port for which to list parameters.

15 Troubleshooting configuration problems This chapter provides information about simple troubleshooting procedures that are designed to help you solve common DTC configuration problems. It does not cover procedures for resolving DTC hardware problems. Refer to your DTC hardware manual for information about how to use the DTCs diagnostics port to troubleshoot hardware problems.
15 Troubleshooting overview The following flowchart outlines troubleshooting procedures that may help you locate the problem. These steps are explained in the following pages.
Checking the result of the DTC self-test Checking the result of the DTC self-test When a DTC is switched on it runs a hardware self-test. Some errors which occur during the self-test are recoverable, while others are not. For example, errors 6X, 7X, 8X, 90, AX, and BX are Serial Interface Card or Connector Card errors for DTC 16s and DTC 48s. These are recoverable errors. If they occur, one or more ports of the DTC may not operate, but the self-test can complete successfully and the DTC will be downloaded.
15 Checking the DTC download Checking the DTC download If the power-on self-test is successful, the DTC broadcasts a boot request on the LAN, and waits for a host running DTC Manager/UX software to download it. The HP 9000 which on which the DTC was configured receives and responds to the boot request. The DTC is ready only after the download operation is successful. The following steps describe how to ensure that the DTC configuration is downloaded from the DTC Manager/UX to the DTC.
Checking the log files Checking the log files In general, reading the appropriate log file can provide you with a better idea of where the problem is. The log files are as follows: • For dtcconfig, look in /var/opt/dtcmgr/log/dtcconfig.log. • For dtcmodifyconfs, look in /var/opt/dtcmgr/log/dtcmodifyconfs.log. • For dtclist, look in /var/opt/dtcmgr/log/dtclist.log. • For dtcdiag, look in /var/opt/dtcmgr/log/dtcdiag.log. • For rbootd, look in /var/adm/rbootd.log.
15 Checking that the DTC management daemons are running Checking that the DTC management daemons are running Download problems The rbootd daemon is a process which runs on the HP 9000 host and is responsible for downloading DTCs. The rbootd process can be started automatically when the HP 9000 is booted. If rbootd is not running, the HP 9000 host cannot respond to a DTC download request. Proceed as follows: 1 Follow the procedures in chapter 3 to verify that the daemons are running.

D Glossary A address A numerical identifier defined and used by a particular protocol and associated software to distinguish one node from another. address resolution In networks, the mapping of node names to IP addresses and the mapping of IP addresses to low-level hardware addresses. address resolution protocol (ARP) A protocol used to convert an IP address to a low-level hardware address. ARP can be used only over a single physical network and is limited to networks that support hardware broadcast.
D B baud rate The measure of the speed at which information travels between devices, most commonly used in reference to terminal speed settings. Baud represents signal events per second. When one bit represents each signal change, baud is the same as “bits per second.” binary mode A data-transfer scheme in which no special character processing is performed. All characters are considered to be data and are passed through with no control actions being taken.
D D Data See DTC. communications and Terminal Controller datagram A self-contained packet that is independent of other packets. It does not require an acknowledgment and it carries information which is sufficient to route it from the source device to the destination device. The DTC Manager/UX uses HP-proprietary datagram protocols. DDFA DTC Device File Access utilities. A set of HP-UX utilities used by systems and user-written applications to programmatically access devices attached to DTC ports.
D direct-connect device An asynchronous device that is connected directly to a DTC through an RS-232-C or RS-423 cable, with no intervening communications equipment. Also referred to as a “local connection.” DNS (Domain Name A system on a network that resolves names into IP addresses, so that connections Server) can be made using names rather than IP addresses. download The process of loading operating code and configuration files into the DTC's memory.
D DTC node name A unique name used to identify a DTC on a LAN. The node name format is nodename.domain.organization, with each of the three parts having up to 16 characters. The name must begin with either a letter or a digit. DTC switching A facility enabling terminal users to select any host system that they want to connect to. DTC user interface The interface accessed by users of terminals connected to a DTC. The default DTC user interface prompt is DTC> DTE Data Terminal Equipment.
D H handshaking A communications protocol between devices or between a device and the CPU. It provides a method of determining that each end of a communications link is ready to transmit or receive data, and that transmission has occurred without error. hardware handshake Uses modem signals CTS and RTS to pace the data transfer from the DTC to the attached device. (For DTC 72MX and DTC 16TN only.) host-based network management A method of managing asynchronous communications for HP computers.
D IP address Internet Protocol address. An address used by the Internet Protocol to perform internet routing. A complete IP address consists of a network portion and a node portion. The network portion of the IP address identifies a network, and the node portion identifies a node within the network. The IP address of each node in the network must be unique within that network. IP datagram The basic unit of information passed across the Internet.
D MAU See Medium Attachment Unit. medium attachment unit (MAU) A device attached to a ThickLAN coaxial cable that provides the physical and electrical connection from the AUI cable to the coaxial cable. MDP Modem Distribution Panel; a distribution panel that serves as the electrical and physical interface between a DTC 16TN or a DTC 72MX MUX board (asynchronous processor board), and up to eight asynchronous devices for direct or modem connections. Also called ADP. MIB Management information base.
D Network Services Software application products that can be used to access data, initiate processes, and exchange information among nodes in the network. NFT Network File Transfer. The network service that transfers disk files between nodes on a network. NI See network interface. node A device on a network. The DTC is also considered to be a node and has its own address. node address The node portion of an IP address. An IP address consists of a node portion and a network portion.
D port groups In the DTC 16TN and DTC 72MX, the ports are grouped into port groups. Each port group has eight ports. The DTC 16TN has two port groups, and the DTC 72MX has three port groups per board. Each port group can be modem or direct-connect. A port group corresponds to a connector on a board of a DTC 72MX or to a connector on a DTC 16TN. printer name A character string of up to 16 characters specified in the DTC Manager configuration to define a printer by name.
D S serial device Any device that is attached to and communicates with a computer by means of a serial transmission interface. Terminals, some printers, and plotters are among the devices that communicate serially with computers. serial transmission A method of transferring data in which characters are transmitted one bit at a time and received one bit at a time in the order of transmission. This transmission scheme is employed by devices connected to the systems via the DTC. SIC Serial Interface Card.
D subnet mask A 32-bit number that enables the node address portion of an IP address in a subnetwork to be identified. Bits in the subnet mask are set to 1 if the network treats the corresponding bit in the IP address as part of the network address, and to 0 if the network treats the corresponding bit in the IP address as part of the node address. The subnet mask 11111111 11111111 11111111 00000000 (or 255.255.255.
D T TCP See Transmission Control Protocol. terminal name A character string of up to 16 characters specified in the DTC Manager configuration to define a terminal by name. Transmission Control Protocol (TCP) A network protocol that establishes and maintains connections between nodes. TCP regulates the flow of data, breaks messages into smaller fragments if necessary (and reassembles the fragments at the destination), detects errors, and retransmits messages if errors have been detected.
