Opening a Configuration or Directory File
The Open Configuration/Directory File screen shown in figure 3-1 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 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 the steps below.
At the Open Configuration/Directory File screen:
1. Enter the name of the file you want to create in the Configuration
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 NMCONFIG.PUB.SYS. You may use the default
if no NMCONFIG.PUB.SYS file currently exists.
2. 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.
3. Press the [Open Config] 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 Main screen will appear and you can proceed with
subsystem configuration.
NOTE Instead of creating a new, and therefore empty, configuration file,
you may want to use the sample configuration file provided by
Hewlett-Packard for use as a configuration template. To do so, see
the instructions that follow for "Copying a Configuration File".
Copying a Configuration File.
Most 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.
1. Purge or rename any existing NMCONFIG.PUB.SYS. (Take care when
doing this that you do not destroy useful configuration
information.)
2. 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.
3. 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
4. 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 Name.
NMMGR 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 the steps below.
At the Open Configuration/Directory File screen:
1. 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.
2. 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.
3. 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 the steps below.
At the Open Configuration/Directory File screen:
1. 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.
2. 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.
3. 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 File
If you want to open an existing network directory file to modify its
directory information, follow the steps below.
At the Open Configuration/Directory File screen:
1. 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.
2. 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.
3. 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.)
