(Tunable Kernel Parameters)
NAME
pci_error_tolerance_time - time interval, in minutes, between two PCI errors at a I/O slot that will result
in automatic PCI Error Recovery
VALUES
Default
1440 (24 hours)
Allowed values
0 (disabled) or non-zero (enabled)
Recommended values
1440
DESCRIPTION
pci_error_tolerance_time
is a dynamic tunable that corresponds to time interval in minutes. It
determines whether an automatic PCI Error Recovery should be initiated or not between two PCI errors
occurring at an I/O slot. If two PCI errors occur at a slot within this specified time interval, the PCI card
in the slot will be suspended and a manual PCI Error Recovery operation will have to be performed to
make the card functional. Refer to the PCI Error Handling section of the olrad (1M) manpage for more
details regarding the manual PCI Error Recovery operation.
Who Is Expected to Change This Tunable?
System administrators can change the value of
pci_error_tolerance_time based on the frequency
of PCI errors seen in the system.
Restrictions on Changing
None. This tunable is dynamic. Changes to this tunable take effect immediately.
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 parame-
ter 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 HP-UX Release Notes at
