some changes, however, that you may make while the network is
operating. Refer to your product-specific manuals for details on changes
that can be made online.
The Backup Configuration File
You specify a backup configuration file name whenever you open or
create a configuration file. The default backup configuration file name is
NMCBACK.group.account, where group and account are the logon
group and account. You may change the name of the file by typing a new
name in place of the default. The backup file also has the file type
NCONF. Each time a subsystem is successfully validated, the backup
file is automatically updated with the configuration information. In the
event that something should occur to cause your active configuration
file to be corrupted, you can rename the backup file and avoid having to
recreate NMCONFIG.PUB.SYS from scratch.
The Sample Configuration File
Hewlett-Packard provides a sample configuration file with every
HP 3000 Series 900 system. This file contains some basic configuration
information for the link, NRJE, SNANODE, IMF, DTS and logging
subsystems. It can be used as a template to help you when you are
creating a new system configuration. The sample file is named
NMSAMP1.PUB.SYS. To use the sample file, make sure you copy it to a
new name, then run NMMGR and modify the copy that you just created
so that it contains your system’s configuration information.
NOTE Check “Copying a Configuration File” in Chapter 3, “Using NMMGR in
Screen Mode,” for important information about this procedure.
The Network Directory File
NMMGR stores network directory information for the NS subsystem in
a second special file called the network directory file. This file, of file
type NDIR, contains information required for one node to communicate
with another node in an internetwork (network of networks).
The network directory file must be named NSDIR.NET.SYS but, like
the configuration file, you may create a directory file under another
name and rename it when you are ready for the system to use the
directory information it contains.
NOTE A network directory uses a KSAM file pair. Therefore, if copying a
directory, be sure to copy both the data file and the key file. If the file
name you create is NSDIR.NET.SYS, the KSAM pair of the file will be
named NSDIRK.NET.SYS, and its file type will be KSAMK.
