ipmi_watchdog_action(5) 					File Formats Manual					   ipmi_watchdog_action(5)

NAME

       ipmi_watchdog_action - sets action taken if IPMI watchdog timer expires

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       The value used depends on what the system administrator wants to happen if the system can not make forward progress.

DESCRIPTION

       The tunable sets the watchdog timer expiration action on systems with the IPMI (Intelligent Platform Management Interface) watchdog timer.

       To tell if a system has this feature use If is listed, the IPMI watchdog timer is supported.

       HP's  Itanium  Product  Family systems and recent PA RISC systems use IPMI as part of the system manageability infrastructure.  IPMI uses a
       "watchdog timer" to detect conditions where the operating system has hung or is not responding.	The action configured  using  the  tunable
       will take place automatically when this situation occurs.

       For instance, if set to the system (or partition, on cellular systems) will hard reset if the OS is hung or not responding.

   Who Is Expected to Change This Tunable?
       System administrators that want the system to take an action if system forward progress stops.

   Restrictions on Changing
       None.  This tunable is dynamic.

   What Other Tunable Values Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at

NAME

       hires_timeout_enable - enable high resolution timers support

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       unless applications require high resolution timers.

DESCRIPTION

       is  a  dynamic  tunable	that enables/disables support for high resolution timers and timed sleep for the following Application Programming
       Interfaces (APIs) - and With the higher resolution, these interfaces can be expected to support time intervals less than the current 10 ms.

   Who Is Expected to Change This Tunable?
       System administrators who need higher than default resolution for applications.

   Restrictions on Changing
       changes take effect immediately.  However, changes to this tunable will not affect timed events already queued.

   When Should the Value of This Tunable Be Raised?
       The value of should be set to if applications require higher resolution for proper operation.  Changes will be system-wide.

   What Are the Side Effects of Raising the Value?
       The number of timer-related interrupts may increase.

   When Should the Value of This Tunable Be Lowered?
       The value of may be set to if there is no longer any overriding need for higher than default resolution.

   What Are the Side Effects of Lowering the Value?
       Fewer timer-related interrupts.

   What Other Tunable Values Should Be Changed at the Same Time?
       None
