TFDS
TFDS
HP Tandem Failure Data System (TFDS) is available on the TNS/E platform and
provides hardware, software, and subsystem failure analysis and automated processor
reload and dump capabilities.
Differences between First Failure Data Capture (FFDC) on G06.nn RVUs and what is
available on the Integrity NonStop NS-series server include:
•
TFDS now supports processor failures due to hardware problems in addition to
software problems.
•
NSAA allows a halted processor to be reloaded immediately and dumped after the
reload is complete without significant impact to that processor.
•
Different files are collected as part of the processor dump function.
•
Some TFDSCOM commands have been added, some have changed, and some
have been eliminated.
•
Some TFDS configuration options have been added, some have changed, and
some have been eliminated.
•
Some API options are no longer available.
•
The published DDL structures are fewer than on NonStop S-series servers.
•
The legacy API remains a run-time library, but the new Trigger API is a source
module.
•
EMS templates are adapted for Integrity NonStop NS-series systems for new
tokens and new messages.
•
Some TFDS commands and configuration options are not applicable to H-series.
For more information, see the TFDS manual and the NonStop NS-Series
Operations Guide.
WHOHAS
WHOHAS looks for openers of a specified object, such as a disc file, communications
device, or process. WHOHAS reports the openers of the device. For disc files,
WHOHAS also reports which users use the file as a swap file and which processes
execute code from the file.
