Customer Messaging Policy - HP AB464-9003F Service Manual

A secondary role of the I/O subsystem is to transfer data between the internal registers within
each CPU core and the internal control/store registers within the zx2 / PDH / Local Bus Adapters
(LBA) and HBA chips. This process is referred to as programmed I/O and is initiated by logical
CPUs executing external LOAD / STORE instructions.
NOTE: Both system firmware and OS kernel use this method to initiate DMA transfers.

Customer Messaging Policy

Always point customer to the SEL for any action from low level I/O subsystem faults as there
may not be any lighted LEDs on the diagnostic panel. (Note that IPMI events in SEL / FPL
provide the logical Acpi path of suspect I/O subsystem CRU. Use
Slot-Rope-ACPI Paths" (page 165)
For configuration style errors, for example, no iLO 2 MP / core I/O HBAs installed or working,
see the Supported Configurations subsection for actions.
Some diagnostic messages are reported for high level I/O subsystem errors; all fatal I/O
subsystem errors cause global MCAs.
NOTE:
FRU. Use
PCI slot number.
Table 60 lists the I/O subsystem events that light the diagnostic panel LEDs.
