Description
This document will describe how to read a device path, and determine the
location of a PCI card mounted on a PCI I/O board in a Sun Enterprise[TM]
3X00-6X00 server.


Steps to Follow
The device path for a PCI I/O board, installed in a Sun Enterprise 3X00-6X00
server, will look similar to the following:
/pci@x,4000/scsi@2

To compute the slot location of the PCI board in the server, divide x by 2.
The whole number quotient indicates the slot number. If there is a remainder of
0, the PCI card is located in the PCI 0 slot of the I/O board. If the remainder
is 1, it is located in the PCI 1 slot of the I/O board.

/pci@x,4000/SUNW,isptwo@3 is the device path (or physical name) for the onboard
UltraSCSI port on a PCI I/O board. This port is controlled by the PCI 1 Psycho
chip on the board.

/pci@x,4000/SUNW,hme@1,1 is the device path (or physical name) for the onboard
fast ethernet port on a PCI I/O board. This port is controlled by the PCI 0
Psycho chip on the board.

Example device path:

/pci@6,4000/scsi@2

From this example, it can be determined that the PCI I/O board is in slot 3
of the server (6 divided by 2 = 3). There is no remainder, so the SCSI
card is in the PCI 0 slot of the PCI I/O board.

These are some common driver names that may appear in a device path.
This is to help identify different cards that may be installed.

fas  - driver for fast/wide SCSI controllers
hme  - driver for Fast Ethernet
isp  - driver for differential SCSI controllers and the SunSwift card
glm  - driver for UltraSCSI controllers
scsi - driver for Small Computer Serial Interface (SCSI) devices
sf   - driver for soc+ or socal Fiber Channel Arbitrated Loop (FCAL)
soc  - driver for SPARC(R) Storage Array (SSA) controllers
socal - driver for serial optical controllers for FCAL (soc+)

NOTE: This information is correct for Open Boot Prom(OBP) version 3.2.30
and above.
