RVUs
This appendix describes the differences between the X25AM subsystem on
NonStop S-series servers and the X25AM software on systems running D-series
RVUs.
In addition to this appendix, the following conversion information is available to help
you:
•
The MIGSCF program can automatically convert to SCF any Configuration Utility
Program (COUP) commands entered at the TACL prompt or found within a
command or OBEY file. MIGSCF documentation can be found in an appendix of
the SCF Reference Manual for G-Series RVUs, or at
$SYSTEM.ZMIGSCF.MANUAL, a read-only TEDIT file.
•
From within SCF, if you enter a COUP command, SCF displays information to help
you convert the command to its SCF equivalent.
WAN Subsystem
For systems running D-series RVUs, X25AM lines are created with the System
Generation (SYSGEN) program. SCF can be used to alter and monitor lines. The
Dynamic System Configuration’s (DSC) COUP program is used to start X25AM lines
and processes.
For systems running G-series RVUs, the X25AM I/O processes are configured and
started with SCF commands to the WAN subsystem. The WAN subsystem SCF
commands that are relevant to the X25AM subsystem are described briefly in
Section 3, Configuring an X25AM Subsystem. For detailed information about the WAN
subsystem, see the WAN Subsystem Configuration and Management Manual.
On systems running G-series RVUs, the WAN subsystem provides the functions that
COUP and SYSGEN provide on the systems running D-series RVUs. Specifically, the
WAN subsystem allows you to:
•
Define X25AM I/O processes with the modifiers that affect their operation
•
Start and stop X25AM I/O processes
•
Alter or delete X25AM I/O processes
•
Monitor X25AM processes and restart them if both the primary and backup
processes fail
Note. There X25AM subsystem on G-series and H-series RVUs are the same. There are no
G-series to H-series migratory considerations for this subsystem.
