High Speed Link (HSL) or PCI bridge card slot resource failure.
Response
A system PCI bus failure was detected. Word 7 of the SRC
contains the bus number.
This failure can occur when a tower in an HSL loop is
powered off using concurrent maintenance. If this is the case, close
this problem.
This error is most likely in the hardware that makes up the
PCI bus, the PCI bus side of the HSL I/O bridge or the
Multi-adapter Bridge or PCI Bridge. In some cases it may be caused by a
failing IOP in the Multi-adapter Bridge or PCI Bridge domain. When an
IOP is causing the problem, the failing IOP cannot be
identified.
NOTE: This SRC can occur for the PCI bus resource
on a PCI bus in an I/O expansion unit when the unit is powered off for a
concurrent maintenance action.
If the Service Action Log, or serviceable event
view on the hardware management console or service processor, is available then
use the failing item list presented there for servicing this
reference code.
If a serviceable event view is not available then use the
failing item list documented here.
NOTE: A fiber optic cleaning kit may be required for optical
HSL connections.
