ipmi_watchdog_action(5)ipmi_watchdog_action(5)NAMEipmi_watchdog_action - sets action taken if IPMI watchdog timer expires
The value used depends on what the system administrator wants to happen
if the system can not make forward progress.
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 watch‐
dog 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?
All HP-UX kernel tunable parameters are release specific. This parame‐
ter may be removed or have its meaning changed in future releases of
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 val‐
ues. For information about the effects of installation on tunable val‐
ues, consult the documentation for the kernel software being installed.
