DESCRIPTION
HP-UX supports PCI Error Handling/Recovery to ensure that PCI
errors caused by bad cards do not crash a hard partition on
high end systems.
This functionality helps in recovering the
most common parity errors.
This tunable is made static because
it is very hard to modify hardware capability at run time.
pci_eh_enable
is made public so certain service guard users would be able to
turn off the functionality.
Who Is Expected to Change This Tunable?
Recommended for service guard customers.
Restrictions on Changing
Changes to this tunable take effect at next reboot.
When Should the Tunable Be Turned On?
This tunable should be turned on to enable PCI Error Recovery
functionality
When Should the Tunable Be Turned Off?
To disable PCI Error Recovery functionality
What Are the Side Effects of Turning the Tunable Off?
PCI Error Recovery functionality will be disabled
WARNINGS
Even if tunable is
ON,
PCI Error Handling/Recovery functionality will be disabled if the
platform does not have the capability.
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 tunable values, consult the documentation
for the kernel software being installed.
For information about optional kernel software that was
factory installed on your system, see
