A file conversion utility called NMMGRVER.PUB.SYS allows you to convert earlier versions of subsystems for use with the current version of Node Management Services (NMS) by converting the files to an acceptable format.

When to Convert Files

If you have not successfully converted your files you will be notified that conversion is necessary when you try either to run NMMGR or to perform a NETCONTROL command. If you attempt to run NMMGR against an unconverted configuration file you will receive the message:

Version mismatch found on specified subsystem. Please run NMMGRVER. (NMGRERR 53)

If you attempt to perform NETCONTROL while using unconverted files you will receive the following message at the console:

Bad CONFIG File Version

In either case you should stop your current activity and run the NMMGRVER.PUB.SYS file conversion utility on your configuration files.

WARNING! The conversion procedure that follows will not preserve any previously configured Distributed Terminal Subsystem (DTS) configuration values. If you are updating from an earlier version of MPE/iX at the same time you are migrating from NS 3000/V to NS 3000/iX, you should see the information under "Updating From a Previous MPE/iX Version" later in this Appendix before converting your configuration files.

Converting Files

Follow these steps to convert configuration files using NMMGRVER:

  1. Make a backup copy of the existing configuration files.

  2. Install a copy of the MPE/V NMCONFIG file to NMCONFIG.PUB.SYS on the MPE/iX system, and then install copies of any NSCONF files.

  3. Execute NMMGRVER.PUB.SYS by entering:

    RUN NMMGRVER.PUB.SYS

    The system responds with the following banner:

    NMS Configuration File Conversion Utility 32099-11018 V.uu.ff (C) Hewlett-Packard Co. 1985

  4. The system will then prompt for the name of the configuration file to be converted by displaying the message:

    Fileset to be scanned?

    You can then choose to end the conversion program by pressing the [RETURN] key, or you can enter one of the following filesets:

    filename [.groupname [.acctname]]

    @ [.groupname [.acctname]]

    @.@ [.acctname]

    @.@.@

    NMMGRVER searches for files of type nconf in the specified fileset. For each file found, it asks:

    OK to convert filename.groupname.acctname?

    where filename.groupname.acctname is the name of a configuration file. Enter Y for yes, or enter either N or [RETURN] for no.

  5. NMMGRVER checks the configuration file to determine whether it is an MPE/V or an MPE/iX configuration file. If it is an MPE/iX file the conversion proceeds without further user input. If the file is an MPE/V file, however, NMMGRVER prompts you for the type of MPE/V file you are converting, as follows:

    What is the type of this file?

    1) MPE V NSCONF
    2) MPE V NMCONFIG
    3) skip this file

    Enter a value between 1 and 3.

    Enter the appropriate value.

  6. After each file is converted NMMGRVER will display the following message:

    FILE CONVERTED

    Continue to enter either Y, N, or [RETURN] until you have converted all files.

In the conversion process, NMMGRVER will merge the information from each NSCONF file accepted for conversion with NMCONFIG.PUB.SYS, and create new (converted) NSCONF files. If you have converted more than one NSCONF file, you will need to choose the file that corresponds to the network configuration you want, and rename it as the new NMCONFIG.PUB.SYS. Choose the NSCONF file that corresponds to the network configuration you want to use as your NS 3000/iX configuration.

This new NMCONFIG.PUB.SYS file contains your NS configuration in a format acceptable to MPE/iX. You can now run NMMGR to configure the DTS subsystem, and to perform any needed modifications to the NS configuration. See "Reconfiguration Guidelines" later in this appendix.

Updating From a Previous MPE/iX Version

Updating from an earlier version of MPE/iX at the same time migrating from NS 3000/V to NS 3000/iX, you will need to make a choice between reconfiguring Distributed Terminal Subsystem (DTS) and reconfiguring the NS network. The choice is necessary because MPE/V versions of NMCONFIG.PUB.SYS files do not include DTS configuration values.

The circumstances of the installation determine which configuration values to preserve. If the NS network is complex, you may decide to convert the existing MPE/V configuration files, and reconfigure DTS. In this case you should follow the steps under "File Conversion Guidelines" earlier in this appendix.

If, on the other hand, your DTS configuration is extensive, you may decide to migrate your existing MPE/iX configuration files to the new version of MPE/iX. You will then need to redo your NS network configuration so that both the NS and DTS configurations are contained in a single, valid, MPE/iX NMCONFIG.PUB.SYS file. In any case, you will need to reconfigure either NS or DTS if you are both updating MPE/iX and converting from an NS 3000/V network to an NS 3000/iX network.
