Convert HW path to device name

[Jean-Marc Beaudoin_1]

Good day,

Is there a fast way to convert a HW path from ioscan to the device name associated to be used within a script.

Example: 0/0/12/1/0/4/0.110.27.19.0.4.1 is /dev/dsk/c26t4d1

Actually I am looking for a simple HP-UX command that will return the /dev/dsk/c26t4d1 for 0/0/12/1/0/4/0.110.27.19.0.4.1 entered

Is that possible ?

ioscan -H 0/0/12/1/0/4/0.110.27.19.0.4.1 -fn

and a little Perl or awk should get you there.

Not really.

The only part of the hw path reflected in the device file is

0.4.1

out of

0/0/12/1/0/4/0.110.27.19.0.4.1

The part "0.4.1" indicates a LUN# 31 and will result in a device file

cxt4d1

The "x" depends.

But you can run

"ioscan -fnH 0/0/12/1/0/4/0.110.27.19.0.4.1"

and awk/grep the device file from the result.

tks all

$disks = system("ioscan -H $device -fn|grep dsk");

returns only the /dev/dsk and /dev/rdsk entry which is EXACLTY what I was looking or.

Retards,

Hey;

ioscan -funC disk -H ${hw} | tail -1 | awk '{print $NF}'
