Backup Configuration File
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. 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 the active configuration file to be
corrupted, rename the backup file and avoid having to recreate
NMCONFIG.PUB.SYS from scratch.
Sample Configuration File
Hewlett-Packard provides a sample configuration file with every
HP e3000 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 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 was 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.
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.
