Hard Partition Hardware Path Format
new at 11i
original release
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
nPartition server 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. Use the rad -q command to list all PCI slots and their
corresponding hardware paths.)
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.
