Methods of turning processor deallocation on and off
Dynamic Processor Deallocation can
be enabled or disabled by changing the value of the cpuguard attribute
of the ODM object sys0.
The possible values for the attribute are enable and disable.
The default is enabled (the attribute cpuguard has
a value of enable). System administrators who want
to disable this feature must use either the system menus, the SMIT System
Environments menu, or the chdev command.
(In previous AIX® versions,
the default was disabled.)
Note: If processor deallocation is turned off (disabled), the errors
are still logged. The error log will contain an error such as
CPU_FAILURE_PREDICTED,
indicating that AIX was
notified of a problem with a CPU.
