a local disk / DVD or from a remote disk on another server through multiple LAN transfers. This
process is referred to as Direct Memory Access (DMA) and is initiated by I/O devices located in
core I/O or on Host Bus Adapter (HBA) I/O cards and does not involve any logical CPUs.
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 Table 61: “PCI/PCI-X
Slot-Rope-ACPI Paths (page 165) to determine the physical PCI slot #.)
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: HP-UX provides its own path with the physical Rope # of the suspect I/O subsystem
FRU. Use Table 61: “PCI/PCI-X Slot-Rope-ACPI Paths (page 165), to determine the physical
PCI slot number.
Table 59 lists the I/O subsystem events that light the diagnostic panel LEDs.
