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 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 Superdome systems.
hd_fabric Driver |
|
The HP-UX 11i install kernel does not include a /stand/system entry for hd_fabric, a new 11i driver. However, this entry is added to the system
file as part of the installation process on Superdome systems. When
the /usr/sbin/mk_kernel command builds a kernel, the hd_fabric driver is built into the HP-UX kernel.
The hd_fabric driver supports partition configuration commands (/usr/sbin/parstatus and others) and related functionality in the Partition
Manager, although it is not required for booting Superdome system partitions.
This affects all three Superdome systems -- Superdome 16-way, Superdome
32-way, and Superdome 64-way. HP-UX kernels built with hd_fabric present in the system file will not cause compatibility issues on
non-Superdome systems.
