WAN Subvolume Resolution
For more information about the system configuration files, see the NonStop NS-Series
Planning Guide or NonStop S-series Planning and Configuration Guide.
WAN Subvolume Resolution
During the configuration of WAN objects, the WAN manager process is provided with
files. The files are specified for the KERNELCODE attribute, SNMPCODE attribute,
IOPOBJECT attribute, and PROFILE object.
The WAN manager process uses the persistence principle to resolve the file in the
current SYSnn/CSSnn to locate the files so the most recent files are being used even
when the SYSnn/CSSnn changes.
The WAN manager process resolves the subvolume by using this algorithm:
1. First, the WAN manager process checks for the file in the current SYSnn/CSSnn.
2. If the file does not exist in the current SYSnn/CSSnn, the WAN manager process
checks for the file in the SYSTEM subvolume.
3. If the file does not exist in the SYSTEM subvolume, the WAN manager process
checks for the file in the specified subvolume.
Autosaved CONFIG CONFSAVE Contains an automatically saved version of the
current CONFIG file that the operating system
automatically creates when you load the sys-
tem from a CONFBASE or CONFxxyy file to
abandon a corrupt configuration.
SCF Command File SCF0000 Contains SCF commands that configure key
system processes and devices, including the
WAN subsystem manager process and WAN
subsystem processes and objects.
SCF and TACL
Command File
STARTCOM Contains SCF and TACL commands that
configure TCP/IP processes (and LISTNER
and TELSERV processes) used to support the
LAN adapters defined in the SCF0000 file.
SCF Command File STARTSCF Contains SCF commands that configure and
start the TCP/IP SUBNET and ROUTE objects
for the TCP/IP processes defined in the
STARTCOM file. This file also contains SCF
commands that start the SWAN concentrators.
*When you load your system for the first time, you specify the CONFIG file and your system starts with the initial
manufacturing configuration as described in Initial WAN Subsystem Configuration
on page 1-1.
Note. This algorithm applies only if the volume is a system disk (usually $SYSTEM).
