Enabling or Disabling Freeze on a Processor
Enabling freeze on a processor, as long as system freeze is also enabled, ensures that
the processor halts when another freeze-enabled processor halts. Enabling freeze on a
processor also ensures that it halts when the System Freeze action is performed.
Disabling freeze on a processor ensures that the only time the processor halts is when
it initiates the halt itself. However, if system freeze is disabled, when one processor
halts, other processors in the server do not halt regardless of whether they are freeze-
enabled or freeze-disabled.
You can check the Processor Freeze attribute using the TSM Service Application or
the OSM or TSM Low-Level Link. However, you can perform the Processor Freeze
Enable and Processor Freeze Disable actions using only the OSM or TSM Low-Level
Link.
Caution. Enabling and disabling freeze on a processor is used primarily for troubleshooting
server problems and is not a normal server operation. Perform this operation only if instructed
to do so by your service provider.
