Operational Differences Between
Systems Running D-Series and
G-Series RVUs
Users familiar with systems running D-series RVUs will find several major differences
in the operational environment of systems systems running G-series RVUs. Although
many of the operations to be performed remain the same, the tools you use to execute
these operations might differ significantly. For G-series RVUs, these changes have
been made:
•
The TSM package replaced several of the maintenance and diagnostic tools with
which you might be familiar. At G06.21, OSM was released as the system
management tool of choice, although TSM is still supported.
•
The Communications Management Interface (CMI), Peripheral Utility Program
(PUP), and Configuration Utility Program (COUP) products are replaced by
enhancements to the Subsystem Control Facility (SCF). Functions performed by
these products on systems running D-series RVUs are performed by SCF on
systems running G-series RVUs.
•
The ServerNet fabrics replace interprocessor buses and I/O channels.
•
Devices and most system processes are configured by SCF, not the SYSGENR
system generation program. As a result, most CONFTEXT configuration file
paragraphs have been removed.
•
The system is started using the OSM or TSM Low-Level Link.
•
Events and event logs can now be monitored by the OSM or TSM Event Viewer.
•
Tape subsystems are managed by MEDIACOM and SCF, not TAPECOM.
•
Disk subsystems are managed by the OSM Service Connection, the TSM Service
Application, and SCF.
•
Online monitoring of system resources is performed by the ViewSys product, OSM,
and TSM.
•
Processor halts are displayed by the Processor Status dialog box of the OSM or
TSM Low-Level Link.
•
Installation of the operating system and software product revisions (SPRs) is now
performed only by the Distributed Systems Management/Software Configuration
Manager (DSM/SCM), not the Install program.
