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 nPartition 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 the section "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.
- g
The device-specific address such as a SCSI controller
(initiator).
Refer to the ioscan(1M) manpage for details on
using ioscan to list hardware path information.
This hardware path format is used only on nPartition systems.
