Operational Differences Between
Systems Running G-Series and
H-Series RVUs
Users familiar with systems running G-series RVUs will find several major differences
in the operational environment of systems running H-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 H-series RVUs, these changes have been
made:
•
TSM is not supported in H-series. You must use OSM. Also, OSM’s graphical
representation of modular systems has a different look in H-series.
•
In power failures, there is no memory hold-up for H-series. Ride-through is
available only if the customer has a site uninterruptible power supply (UPS) or an
in-cabinet UPS for all the affected cabinets.
•
TAPEBOOT is not supported in H-series.
•
In H-series, native compilers and linkers have new names. Therefore, automated
scripts might require changing.
•
Subvol for public libraries is SYS
nn
in G-series. In H-series, it is ZDLL
nnn
and
requires changing scripts.
•
REPLACEBOOT only applies to TNS and TNS/R. It does not apply to TNS/E.
•
On G-series servers, the OSS shell command
ls
displays the contents of
directories without visually distinguishing between subdirectories and files. On H-
series servers,
ls
displays the contents of directories with a visual distinction
between subdirectories and files -- subdirectory names are suffixed with a slash (/).
This difference affects any OSS shell script that relied upon processing the output
of the
ls
command.
•
For H-series, DSM/SCM installation default is Manage OSS Files. For G-series,
the default is not to manage OSS files.
•
KMSF swap files have a larger memory size. It is now four times memory size per
processor.
•
Changes to automated debugging and dump mechanisms are required in H-series
because of the new debuggers and debugger commands.
•
The H-series OSS environment does not support TNS execution. OSS programs
must be migrated to TNS/E native mode to run on an H-series system.
