DUMPALLSLICES
The DUMPALLSLICES command controls whether or not TFDS performs parallel
dumping (reloading a processor before dumping it) for processor halt codes that have
been specified by the ADD command. For some processor halts, support personnel
need the memory contents of all NSBEs, not just one
ON
directs TFDS to dump all NSBEs of a processor before reloading it. The default
setting is ON.
OFF
directs TFDS to perform the normal, DMR and TMR halt recovery method of
reloading the processor, then dumping the omitted NSBE.
Guidelines
•
The DUMPALLSLICES configuration attribute applies only to DMR and TMR
processors.
•
The current DUMPALLSLICES setting is displayed by the CONFIG DETAIL
command. (For more information, see CONFIG on page 3-15.)
•
Setting DUMPALLSLICES ON has a negative impact on the overall system
performance and availability. This option should be enabled only when
recommended by HP support personnel.
•
When DUMPALLSLICES is set ON, TFDS requires significantly more free disk
space for processor dumps. For TMR processors, required disk space increases
up to three times more than when parallel dumping is used.
