Tree device

Hi,

how can I find the tree device for a given device
for example:
cd0-> ide0 -> pci3
I can find the child for a device with lsdev -p xxx
but if I know cd0 how can I find ide0 then pci3

Thanks in advance (AIX 5.3)

Do you want to identify the parent devices? In this case use lsdev
till you end up with the slot id.
(0)blah:/home/me> lsdev -l cd0 -F parent
ide0
(0)blah:/home/me> lsdev -l ide0 -F parent
pci4

scnr todo the task

$ cat ./lsdevpath
#!/usr/bin/ksh
f_lsdev ()
{
echo $1
lsdev -l $1 -F parent 2>/dev/null | read y
f_lsdev $y
}
set -e
f_lsdev $1 | xargs echo


$ ./lsdevpath hdiskpower10
hdiskpower10 fscsi0 fcs0 pci13 pci3 sysplanar0 sys0


Not multipath save.

I may not be thinking of the right thing (and I don't have a system
handy) but lsdev -Cs scsi shows everything scsi connected, would lsdev
-Cs ide do the same for the ide...probably doesn't show a "tree" but
based on the output, it shouldn't be too hard to associate the location
codes with the ide "base".

Like I said, I don't have a system (with ide devices) handy but...

p.s. lsdev -Cs pci shows all the PCI devices...PS
