HP-UX Hardware Paths on HP Superdome Systems
The HP-UX hardware path on HP Superdome systems is provided in the
format described here. The ioscan HP-UX command reports the
hardware path 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.
The components of Superdome hardware paths are:
a/b/c/d/e.f.g
where these components are as follows
• a
Is the global cell number.
• b
Is a processor (10–13), memory (5), or a system bus adapter (0). Each
Superdome I/O chassis has a single system bus adapter.
• c
Is 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 The LBA number is not necessarily the same as the PCI slot number.
See “HP Superdome PCI I/O Slots and Hardware Paths” on page 29
for important details.
• d
Is 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 and addresses in a single card.
• e
Is the function for the I/O card. Typically this is 0 (zero) for
single-function cards.
