i need some help with the hw path in hp-ux. may someone can help me with that
lets say my machine is a rx8640.
vparstatus -vp (name) | grep -i boot
-> 0.0.1.1.0.4.0.4.0.0.0.0.0 BOOT
as far as i can see from the vparresources manpage its something like
cell/sba/lba/pci_bridge/dev/function and in the hw manual i found
0/0/1/1/0 is cell,pci slot, ropes. so for me 0/0/1/1/0 is clear.
but whats about 4.0.4.0.0.0.0.0. can please someone explain the 8 remaining digits in the way x.y.z..., x means kind of devices or whatever, y lun etc.
thank you very much
regards,
m

Below the point you've figured out, things get complex and depend largely on what sort of devicve this is... for example COMBO cards will have an additional PCI bridge within the card which results in slightly longer HW paths
I'm guessing this is a fibre channel (or maybe SCSI?) device (possibly on a multi-port or multi-function card?)
Anyway for fibre channel at least, take a lkook at a manual for the last part of the HW path:
http://docs.hp.com/en/A6795-90007/ch01s08.html
For a non-network boot device at least you can always be confident that the last 3 digits of the HW path are bus.target.lun

Re: understanding hw path
This is the old notation used in the previous vPars versions at the beginning.
0.0.1.1.0.4.0.4.0.0.0.0.0 (only dots)
Nowadays you can take the path directly from ioscan, e.g.
0/0/1/1/0/4.0.4.0.0
Hope this helps!
Regards
Torsten.
