Operational Differences Between Systems Running

Operational Differences Between Systems
Running H-Series and G-Series
H-series RVUs differ from G-series RVUs in these aspects:
•
In power failures, H-series (TNS/E) systems provide no memory hold-up. Ride
through is available only with a site uninterruptible power supply (UPS) or an in-
cabinet UPS for all affected cabinets.
•
TAPEBOOT is not supported on TNS/E systems. You cannot make a system
image tape (SIT).
•
On TNS/E systems, compilers and linkers have new names. Therefore, automated
scripts require changing.
•
The subvolume for public libraries is SYSnn in G-series RVUs. In H-series RVUs, it
is ZDLLnnn.
•
REPLACEBOOT applies only to TNS and TNS/R, not TNS/E.
•
In G-series RVUs, the DSM/SCM installation default is not to manage HP NonStop
Open System Services (OSS) files. In H-series RVUs, the default is Manage OSS
Files.
•
In H-series RVUs, the default maximum size for default Kernel-Managed Swap
Facility (KMSF) files is 512 MB.
•
In H-series RVUs, you must change automated debugging and dump mechanisms
because of new debuggers and debugger commands.
•
In H-series RVUs, the OSS environment does not support TNS execution. You
must migrate OSS programs to TNS/E native mode to run on a TNS/E system.
•
TSM does not support Integrity NonStop NS-series hardware. You must use the
HP NonStop Open System Management (OSM) Interface to manage your Integrity
NonStop NS-series system.
•
In H-series, the processes for system and processor load are different. You can
load a system or processor from either a Fibre Channel disk or a SCSI disk. The
System Load dialog box in the OSM Low-Level Link, used for both system and
processor load, has changed to present the new load options.
For more information, see System Startup on page 5-5 and:
°
For initial system load (starting the server) and creating an alternate system
disk, see the NonStop NS-Series Hardware Installation Manual.
°
For subsequent starting and stopping (or powering on and off) of the system,
see the NonStop NS-Series Operations Guide.
°
For details on using the System Load dialog box in the OSM Low-Level Link
and specifying alternate system disks in the OSM Service Connection, see the
OSM online help.
