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 SYSnn in G-series. In H-series, it is ZDLLnnn 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.
