Configuration Management
•
Monitoring system resources, including implementation of remote monitoring and
maintenance
For G06.21 and later RVUs, the OSM product replaces TSM as the system
management tool of choice for NonStop S-series systems. OSM offers a
browser-based interface that improves scalability and performance and overcomes
other limitations that exist in TSM. TSM is still supported; however, OSM is required to
support new functionality in G06.21 and later, such as G4SA and IOAM hardware.
For more information about OSM, see the OSM Migration Guide and the OSM User’s
Guide.
Configuration Management
Configuration management is the task of defining and maintaining records of system
and object configurations. Before you can use a resource, someone must define its
configuration. After a failure, its configuration must be restored. Various kinds of
problems—for example, performance problems—can often be solved by adjustments
to object configurations.
DSM/SCM and SYSGENR
To install a new RVU of the operating system, you must run the Distributed Systems
Management/Software Configuration Manager (DSM/SCM), a GUI-based program that
guides you through the complete software installation process. DSM/SCM
automatically runs the system generation program for G-series systems, SYSGENR.
SYSGENR configures the system variables listed in the ALLPROCESSORS paragraph
of the CONFTEXT configuration file. These entries are built by SYSGENR and stored
in the operating system image file, OSIMAGE.
Subsystem Control Facility (SCF)
SCF is the HP online configuration facility for G-series RVUs. After you run SYSGENR
to create the basic configuration, you must use SCF to configure the rest of the
operating system objects. The only type of off-line configuration change that requires
bringing your system down is a change to an ALLPROCESSORS paragraph entry in
the CONFTEXT file. SCF is the tool you use for configuring and controlling all
communications products.
The two main SCF interfaces used to configure local area network (LAN) and wide
area network (WAN) connections are as follows:
