The Open Configuration/Directory File screen shown in Figure 3-1 “Open Configuration/Directory File
Screen” is the first screen you
see when you start NMMGR in screen mode. Figure 3-1 Open Configuration/Directory File
Screen From this screen you can: create a new configuration file open an existing configuration file create a new network directory file open an existing network directory file specify a name for the backup configuration file
The instructions that follow describe how to do each of these
tasks. See Chapter 1 “Introduction” for
more information about configuration files and network directory
files. Creating a New Configuration File | |
If you want to create a new configuration file (one that does
not exist), follow these steps. At the Open Configuration/Directory File
screen: Copying a Configuration FilesMost new configuration files are created from existing ones,
rather than from scratch. You can copy an existing file from the
same system or from a different system on your network. Note that
if you are copying the file to NMCONFIG.PUB.SYS
there are certain rules which must be followed or the new file may
not be found or run when the system is booted. The steps that follow show how to copy the sample configuration
file provided by Hewlett-Packard, NMSAMP1.PUB.SYS,
to NMCONFIG.PUB.SYS. The sample
file is provided for use as a template when you are configuring
a system with no existing configuration. Purge or rename any existing NMCONFIG.PUB.SYS.
(Take care when doing this that you do not destroy useful configuration
information.) Create a file equation similar to the following
example: :FILE CONFIG = NMCONFIG.PUB.SYS; DEV = 1; DISC = 2048,1,1 |
The configuration file must reside on LDEV1, because the system
does not have access to other LDEVs at startup and the configuration
file is needed at that time. Only one file extent is allowed. Copy the appropriate sample file into the empty
CONFIG file. The following is a
sample "copy" command: FCOPY FROM = NMSAMP1.PUB.SYS; TO = *CONFIG; NEW; NOUSER LABELS |
When you are ready to proceed with configuration,
run NMMGR and open the configuration file you just created. See
the instructions that follow for "Opening a Configuration
File."
You may choose to copy your source file to a name other than
NMCONFIG.PUB.SYS first, modify
that file using NMMGR, then rename the file as NMCONFIG.PUB.SYS
when you are ready for it to be used by the system. Changing the Backup File NameNMMGR automatically generates a backup configuration file
that is updated each time the configuration is successfully validated.
By default, the backup file name is NMCBACK.group.account.
You can change the name that will be used for the backup file by
typing a new name in the Backup configuration file name field on
the Open Configuration/Directory File screen. The file name you enter must be a valid MPE file name. If
you do not enter a group or account name, NMMGR will qualify the
file name with your logon group and account. It is a good idea to change the name that will be used for
the backup file if you are modifying an alternate configuration
or one that will be used on a different system. By changing the
backup file name you can avoid writing over a backup file that you
want to maintain. Opening an Existing Configuration File | |
If you want to open an existing configuration file to modify
the configuration, follow these steps. At the Open Configuration/Directory File screen: Enter the name of the file you want to open
in the Configuration file name field. In most cases, you want to make sure that the file you plan
to open is not the active configuration file. If you do not specify a group or account, NMMGR will assume
that the file resides in your logon group and account. If a write access password has been assigned, you must
enter the password in the Write access password field in order to
open the file in write mode. (If you do not enter an assigned password,
you can still access the file in read-only mode.) If no write access
password has been enabled, leave this field blank. Press the [Open Config] key. The Main
screen will appear and you can proceed with subsystem configuration.
The fields on each screen show the values currently entered for
the configuration file you opened.
Creating a Network Directory File | |
If you want to create a new network directory file (one that
does not exist), follow these steps. At the Open Configuration/Directory File screen: Enter the name of the file you want to create
in the Network directory file name field. The name must be a valid MPE file name. If you do not specify
a group or account, NMMGR will qualify the file name with your logon
group and account. The default file name is NSDIR.NET.SYS.
You may use the default if no NSDIR.NET.SYS file
currently exists. If a write access password has been assigned, you must
enter the password in the Write access password field in order to
create a new file. If no write access password has been enabled,
leave this field blank. Press the [Open Directry] key. NMMGR
will ask you to press the key again to verify that you want to create
a new file. Press the key again. The Network Directory Main screen
displays and you can proceed with directory configuration. (See
the Configuration Guide for the subsystem
you are configuring for more information on configuring the network
directory.)
Opening an Existing Network Directory | |
If you want to open an existing network directory file to
modify its directory information, follow these steps. At the Open Configuration/Directory File screen: Enter the name of the file you want to open
in the Network directory file name field. If you do not specify
a group or account, NMMGR will assume that the file resides in your
logon group and account. If a write access password has been assigned, you must
enter the password in the Write access password field in order to
open the file in write mode. (If you do not enter an assigned password,
you can still access the file in read-only mode.) If no write access
password has been enabled, leave this field blank. Press the [Open Directry] key. The
Network Directory Main screen appears and you can proceed to modify
the network directory information. The fields on each screen will
show the values currently entered for the network directory file
you have opened. (See the Configuration Guide
for the subsystem you are configuring for more information on configuring
the network directory.)
