I need explicatio about codification used with ioscan command

malki_3 — Fri, 24 May 2002 11:12:21 GMT

When I use ioscan command
ioscan -f I have an output like that
ba 4 0/4 lba CLAIMED BUS_NEXUS Local PCI Bus Adapter (782)
fc 0 0/4/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
Can anyone explain to me what's the link between 0/4 et 0/4/0/0 and other lines with 0/4/... information H/W Path
Thanks for your help

each slot for cards is hard codified. You can see on the rear of you server for strings as 0/4

This means what bus, card, .... is pluged.

Run xstm to get a physical view of this...

Hi

The 0/4 is the physical hardware path to devices on your system.

If you look at the back of your server you will see that it is marked with these paths.
Each device further down the chain will show where it is and the complete path backwards

from my server

0/4 = PCI Bus Adaptor

0/4/0/0.8.0.255.0.8.0 Seagate disk

The disk I know is in an FC10 so I can trace backwards all devices back to the PCI slot on the backplane (MotherBoard)

The "lba" (driver type) and "BUS_NEXUS" (HW type) on 0/4 tells me that this is a bus converter or bus adapter, in your case a PCI interface. Anything connected at this interface will have 0/4/X/X as its path. Do a ..
# man ioscan
it gives quite good explaination too. A good example of this is say an IDE interface with a CDROM connected to it ..
ext_bus 0 10/0/14/0 side CLAIMED INTERFACE IDE
target 0 10/0/14/0.0 tgt CLAIMED DEVICE
disk 0 10/0/14/0.0.0 sdisk CLAIMED DEVICE LITEON CDROM
