This subsection provides information on troubleshooting issues with the eight public and two private
PCI-X slots.
I/O Subsystem Behavior
The I/O subsystem transfers blocks of data and instruction words between physical shared memory
and virtual memory (system disks/disk array). The system boot is the first time blocks of data and
instructions words are transferred into physical shared memory from a local disk or DVD or from
a remote disk on another server using multiple LAN transfers. This process is referred to as Direct
Memory Access (DMA). It 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.
The I/O subsystem also transfers data between the internal registers within each CPU core and
the internal control registers within the Zx2/PDH/Local Bus Adapters (LBA) and HBA chips. This
process is referred to as programmed I/O. It is initiated by logical CPUs executing external
LOAD/STORE instructions. Both system firmware and the OS kernel use this method to initiate
DMA transfers.)
I/O Messages
• Use the SEL to identify low level I/O subsystem faults if LEDs on the diagnostic panel are not
lit. IPMI events in the SEL and FPL provide the logical ACPI path of the suspect I/O subsystem
CRU. To determine the physical PCI slot number, see Table 62.
• For configuration errors, for example, no core I/O HBAs installed or working, see “Supported
Configurations” (page 139).
• Diagnostic messages are reported for high level I/O subsystem errors. All fatal I/O subsystem
errors cause global MCAs. HP-UX provides its own path with the physical rope number of the
suspect I/O subsystem CRU. To determine the physical PCI slot number, see Table 62.)
Table 60 and Table 61 lists the I/O card events that light and may light the diagnostic panel LEDs.
