Re: h/w path problem

A hardware path of 8/12.5.0 represents a SCSI disk connected to the
system. The number 8 represents a bus in the system. The number 12 is the address of the SCSI adapter
on the bus. The disk is connected to that SCSI adapter at address 5, having a logical unit number 0.
Similarly, hardware address 8/5/0 represents a fiber channel adapter connected to bus 8, bus converter
number 5, and adapter number 0. On the backside of an HP-9000 server, you can see expansion slots,
and some of these numbers may be present there. To list the devices in your system, you can use the
ioscan command, which shows the hardware paths of all devices connected to your system. A typical
output of this command is as follows.
# ioscan -f
Class I H/W Path Driver S/W State H/W Type Description
'
'
'
disk 22 10/12/5.2.0 sdisk CLAIMED DEVICE TOSHIBA CD-ROM
'
'
A short description of the fields in the ioscan command output is presented here.
Class Shows the category of the device.
I Instance: When multiple devices or adapters of the same category are present, they are
distinguished from one another by instance numbers. Usually instance numbers are
assigned at installation time.
H/W Path This is the hardware path as already discussed in this chapter.
Driver Name of the driver that controls the device. The device drivers are built into the HP-UX
kernel. When adding a device that needs a new device driver, the kernel needs to be
reconfigured.
S/W State CLAIMED means the device driver is loaded in the kernel and is bound to the device.
UNCLAIMED means the device driver is not available in the kernel for that device.
H/W Type Shows what type of device it is.

It's kind of fun to do the impossible
