HP Superdome Systems’ Hardware Path Format
The HP-UX hardware path on HP Superdome systems is provided in the
format described here. The HP-UX command ioscan reports the
hardware paths for components within the partition in which the
command is issued.
Note that the ioscan command reports information only for the
currently active hardware components in the local partition. It does not
report details for hardware not assigned to the local partition.
On Superdome systems, HP-UX hardware paths conform to the following
format:
a
/
b
/
c
/
d
/
e
.
f
.
g
The components of a hardware path are as follows:
a
The global cell number
b
A processor (10-13), memory (5), or system bus adapter
(0). Each Superdome I/O chassis has a single system
bus adapter.
c
A local bus adapter (the LBA, one for each PCI card
slot in the chassis). The LBA connects its
corresponding PCI card slot with the system bus
adapter.
Note that the LBA number is not necessarily the same
as the PCI slot number. See thesection “HP Superdome
PCI I/O Slots and Hardware Paths” in Managing
Superdome Complexes: A Guide for HP-UX System
Administrators for important details.
d
The card’s address on the slot’s PCI bus.
Typically this is 0 (zero), although the Superdome core
I/O card has multiple devices in a single card.
e
The function for the I/O card. Typically this is 0 (zero)
for single-function cards.
f
The target of the I/O device, or SCSI ID.
