23 About This Manual General Syntax Notation [ ] Brackets. Brackets enclose optional syntax items. For example: TERM [\system-name.]$terminal-name INT[ERRUPTS] A group of items enclosed in brackets is a list from which you can choose one item or none. The items in the list can be arranged either vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of brackets and separated by vertical lines. For example: FC [ num ] [ -num ] [ text ] K [ X D ] address { } Braces. A group of items enclosed in braces is a list from which you are required to choose one item. The items in the list can be arranged either vertically, with aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example: LISTOPENS PROCESS { $appl-mgr-name } { $process-name } ALLOWSU { ON OFF } Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in brackets or braces. For example: INSPECT { OFF ON SAVEABEND } Ellipsis. An ellipsis immediately following a pair of brackets or braces indicates that you can repeat the enclosed sequence of syntax items any number of times. For example: M address [, new-value ] [ - ] { } An ellipsis immediately following a single syntax item indicates that you can repeat that syntax item any number of times. For example: "s-char " Punctuation. Parentheses, commas, semicolons, and other symbols not previously described must be typed as shown. For example: error := NEXTFILENAME ( file-name ) ; LISTOPENS SU $process-name.#su-name Quotation marks around a symbol such as a bracket or brace indicate the symbol is a required character that you must type as shown. For example: "[" repetition-constant-list "]" HP NonStop TCP/IPv6 Configuration and Management Manual xxi

24 About This Manual Notation for Messages Item Spacing. Spaces shown between items are required unless one of the items is a punctuation symbol such as a parenthesis or a comma. For example: CALL STEPMOM ( process-id ) ; If there is no space between two items, spaces are not permitted. In this example, no spaces are permitted between the period and any other items: $process-name.#su-name Line Spacing. If the syntax of a command is too long to fit on a single line, each continuation line is indented three spaces and is separated from the preceding line by a blank line. This spacing distinguishes items in a continuation line from items in a vertical list of selections. For example: ALTER [ / OUT file-spec / ] LINE [, attribute-spec ]!i and!o. In procedure calls, the!i notation follows an input parameter (one that passes data to the called procedure); the!o notation follows an output parameter (one that returns data to the calling program). For example: CALL CHECKRESIZESEGMENT ( segment-id!i, error ) ;!o!i,o. In procedure calls, the!i,o notation follows an input/output parameter (one that both passes data to the called procedure and returns data to the calling program). For example: error := COMPRESSEDIT ( filenum ) ;!i,o!i:i. In procedure calls, the!i:i notation follows an input string parameter that has a corresponding parameter specifying the length of the string in bytes. For example: error := FILENAME_COMPARE_ ( filename1:length!i:i, filename2:length ) ;!i:i!o:i. In procedure calls, the!o:i notation follows an output buffer parameter that has a corresponding input parameter specifying the maximum length of the output buffer in bytes. For example: error := FILE_GETINFO_ ( filenum!i, [ filename:maxlen ] ) ;!o:i Notation for Messages This list summarizes the notation conventions for the presentation of displayed messages in this manual.

25 About This Manual Notation for Messages Bold Text. Bold text in an example indicates user input typed at the terminal. For example: ENTER RUN CODE?123 CODE RECEIVED: The user must press the Return key after typing the input. Nonitalic text. Nonitalic letters, numbers, and punctuation indicate text that is displayed or returned exactly as shown. For example: Backup Up. lowercase italic letters. Lowercase italic letters indicate variable items whose values are displayed or returned. For example: p-register process-name [ ] Brackets. Brackets enclose items that are sometimes, but not always, displayed. For example: Event number = number [ Subject = first-subject-value ] A group of items enclosed in brackets is a list of all possible items that can be displayed, of which one or none might actually be displayed. The items in the list can be arranged either vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of brackets and separated by vertical lines. For example: proc-name trapped [ in SQL in SQL file system ] { } Braces. A group of items enclosed in braces is a list of all possible items that can be displayed, of which one is actually displayed. The items in the list can be arranged either vertically, with aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example: obj-type obj-name state changed to state, caused by { Object Operator Service } process-name State changed from old-objstate to objstate { Operator Request. } { Unknown. } Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in brackets or braces.

27 1 Quick Start This manual documents NonStop TCP/IPv6 only; it does not document Parallel Library TCP/IP. However, if you configure NonStop TCP/IPv6 in INET mode, NonStop TCP/IPv6 is a direct replacement for Parallel Library TCP/IP. This section provides examples for starting NonStop TCP/IPv6 in INET and DUAL modes. This section does not provide background information about IPv6; to gain a more in-depth understanding of IPv6, see Appendix A, IPv6 Fundamentals, and About This Manual for a list of industry resources on the topic. This section also does not explain the examples. For an explanation of the examples in this section and for procedures for adding more features such as routes and round-robin filtering as well as for how to configure the subsystem in INET6 mode, see Section 5, Example Illustrations and Adding Features to the Basic Configuration. Procedures provided in this section include: I. Prepare to Install and Configure NonStop TCP/IPv6 on page 1-2 IIA. Install NonStop TCP/IPv6 (#ZZTCP is not in the Configuration Database) on page 1-4 OR IIB. Install NonStop TCP/IPv6 (#ZZTCP is in the Configuration Database) on page 1-5 IIIA. Configure the NonStop TCP/IPv6 Subsystem for INET Mode on page 1-6 OR IIIB. Configure the NonStop TCP/IPv6 Subsystem for DUAL Mode on page 1-15 IVA. Prepare to Start the Applications (Without LNP) on page 1-21 OR IVB. Prepare to Start the Applications (With LNP) on page 1-21 VA. Start the Applications (Without LNP) on page 1-22 OR VB. Start the Applications (With LNP) on page 1-22 VI. Add More Features on page 1-24 HP NonStop TCP/IPv6 Configuration and Management Manual

28 Quick Start I. Prepare to Install and Configure NonStop TCP/IPv6 The default mode for the NonStop TCP/IPv6 subsystem is INET (see NonStop TCP/IPv6 Operating Modes on page 2-20). Note. You cannot simultaneously run both the Parallel Library TCP/IP and NonStop TCP/IPv6 subsystems on the same system. Furthermore, Parallel Library TCP/IP is not supported on Integrity NonStop servers. I. Prepare to Install and Configure NonStop TCP/IPv6 Before you install and configure NonStop TCP/IPv6, follow the procedures in this subsection. 1. Check Assumptions Before Starting NonStop TCP/IPv6 Before starting the NonStop TCP/IPv6 subsystem, check that these assumptions are met: The SCF environment is operational (that is, $ZNET is STARTED). QIOMON is running (that is, $ZMnn is STARTED). SLSA is running (that is, $ZZLAN is STARTED). Parallel Library TCP/IP and NonStop TCP/IPv6 are not already running on the system. If NonStop TCP/IPv6 is already running and you want to reconfigure it in a different mode, first stop the subsystem by following the procedures in Stopping NonStop TCP/IPv6 on page 6-7, and then restart it by following the procedures in this section (for INET or DUAL mode) or the procedures in Configure the Basic Subsystem for INET6 Mode on page 5-8. On a NonStop S-series server, if Parallel Library TCP/IP is running, you must stop it by using the procedure Stopping NonStop TCP/IPv6 as a Generic Process on page 6-12, substituting TCPMON and TCPSAM for TCP6MON and TCP6SAM in that procedure. You can also see the TCP/IP (Parallel Library) Configuration and Management Manual, which has a procedure for stopping Parallel Library TCP/IP as a generic process. Note. Issue the SCF LISTDEV TCPIPV6 and LISTDEV PTCPIP commands to determine if either subsystem is running. (Parallel Library TCP/IP is not supported on Integrity NonStop servers.) You are running as user SUPER.SUPER. 2. Prepare to Install and Configure the Subsystem Before performing any of the configurations in these quick start examples, perform the tasks in this subsection. These steps ensure that your environment is ready to run NonStop TCP/IPv6. Variables in the examples are indicated with italics. You must substitute real values from your environment for these variables. HP NonStop TCP/IPv6 Configuration and Management Manual

29 Quick Start 2. Prepare to Install and Configure the Subsystem 1. Check for any issues that affect your configuration. See the TCP/IPv6 Migration Guide. 2. Ensure that the PROTOCOL configuration file in $SYSTEM.ZTCPIP was updated with the ipv6 and icmpv6 lines from the SMPLPROT file on the Site Update Tape (SUT). See PROTOCOL File on page D Select a LIF of TYPE ETHERNET for communications. a. Obtain a list of all LIFs. Enter this command at the SCF prompt: ->STATUS LIF $ZZLAN.* (Do not select LANX or LANY.) b. Using one of the LIF names from Step 3, determine if the LIF is of TYPE ETHERNET by issuing this command at the SCF prompt: ->INFO LIF $ZZLAN.L01A c. Ensure that the LIF you are configuring for NonStop TCP/IPv6 is accessible to all processors on which you plan to run NonStop TCP/IPv6 by entering this command at the SCF prompt: ->STATUS LIF $ZZLAN.L01A, DETAIL The CPUs with Data Path field lists the processors to which the LIF is accessible. d. Make a note of this LIF name for later configuration. Note. To use Ethernet failover and also to service Ethernet 4 ServerNet adapters (E4SAs) or Gigabit Ethernet 4-port ServerNet adapters (G4SAs) without taking down TCP/IP communications, select two LIFs from different adapters. e. Check if the TCP6MAN process has been added as a generic process to the system configuration database by entering this command at the SCF prompt. (If ZZTCP has not been added as a generic process, perform IIA. Install NonStop TCP/IPv6 (#ZZTCP is not in the Configuration Database) on page 1-4 for your installation step. If ZZTCP has been added as a generic process, perform IIB. Install NonStop TCP/IPv6 (#ZZTCP is in the Configuration Database) on page 1-5 for your installation step.) ->STATUS PROCESS $ZZKRN.#ZZTCP 4. Save the system configuration database by entering the SCF command. Substitute the numbering scheme for your system for the variable (01.04). For information about numbering versions of your system configuration database, see the SCF HP NonStop TCP/IPv6 Configuration and Management Manual

30 Quick Start IIA. Install NonStop TCP/IPv6 (#ZZTCP is not in the Configuration Database) Reference Manual for G-Series RVUs or the SCF Reference Manual for H- Series RVUs. ->SAVE CONFIGURATI0N Note. See Configuration Database Management on page 6-14 and Falling Back to Conventional TCP/IP or Parallel Library TCP/IP on page IIA. Install NonStop TCP/IPv6 (#ZZTCP is not in the Configuration Database) If you do not already have #ZZTCP in the system configuration database, follow this procedure for installing NonStop TCP/IPv6. 1. Check considerations that affect your configuration by reviewing the TCP/IPv6 Migration Guide. 2. Add the TCP6MAN process to the system configuration database by entering these SCF commands: ->ADD PROCESS $ZZKRN.#ZZTCP,BACKUPCPU 1, DEFAULTVOL & $SYSTEM.SYSTEM, HOMETERM $ZHOME, NAME $ZZTCP, & OUTFILE $ZHOME, PRIMARYCPU 0, PRIORITY 180, & PROGRAM $SYSTEM.SYSTEM.TCP6MAN, STARTMODE SYSTEM, & STARTUPMSG "<BCKP-CPU>", STOPMODE SYSMSG (For more information about SCF commands for the configuration database, see the SCF Reference Manual for the Kernel Subsystem.) 3. Check that $ZZTCP has been added to the system configuration database by entering this SCF command: ->INFO PROCESS $ZZKRN.#ZZTCP, DETAIL HP NonStop TCP/IPv6 Configuration and Management Manual

31 Quick Start IIB. Install NonStop TCP/IPv6 (#ZZTCP is in the Configuration Database) You should see a display like this: *AutoRestart...0 *BackupCPU...1 *CPU...Not Specified *DefaultVolume...$SYSTEM.SYSTEM *ExtSwap...Not Specified *Highpin...ON *HomeTerminal...$ZHOME *InFile...Not Specified *Library...Not Specified *MemPages...Not Specified *Name...$ZZTCP *OutFile...$ZHOME *PFSSize...Not Specified *PrimaryCPU...0 *Priority *Program...$SYSTEM.SYSTEM.TCP6MAN *SaveAbend...OFF *StartMode...SYSTEM *StartupMessage...<BCKP-CPU> *StopMode...SYSMSG *Type...OTHER *UserId...SUPER.SUPER ( 255,255 ) 4. Start the NonStop TCP/IPv6 subsystem by entering this SCF command: ->START PROCESS $ZZKRN.#ZZTCP 5. Proceed to Step IIIA. Configure the NonStop TCP/IPv6 Subsystem for INET Mode on page 1-6 or Step IIIB. Configure the NonStop TCP/IPv6 Subsystem for DUAL Mode on page IIB. Install NonStop TCP/IPv6 (#ZZTCP is in the Configuration Database) If you already have #ZZTCP in the system configuration database, follow this procedure for replacing Parallel Library TCP/IP with NonStop TCP/IPv6. (This applies to NonStop S-series servers only, since Parallel Library TCP/IP is not supported on Integrity NonStop servers.) 1. Alter the #ZZTCP process to use the NonStop TCP/IPv6 program by entering these SCF commands: ->ASSUME PROCESS $ZZKRN.#ZZTCP ->TIMEOUT ->ABORT ->ALTER, PROGRAM $SYSTEM.SYSTEM.TCP6MAN HP NonStop TCP/IPv6 Configuration and Management Manual
