From hardware path:

0/2/0/0.97.4.19.0.0.=>0<= LUN 0
0/2/0/0.97.4.19.0.0.1 LUN 1
0/2/0/0.97.4.19.0.0.2 LUN 2
0/2/0/0.97.4.19.0.0.3 LUN 3
0/2/0/0.97.4.19.0.0.4 LUN 4
...
0/2/0/0.97.4.19.0.1.0 LUN 8
...

Or from the device file name e.g. /dev/dsk/c11t0d2 would indicate LUN 2 (t*8 + d = 0*8 + 2 = 2) and /dev/dsk/c11t2d2 would indicate LUN 18 (2*8 + 2 = 16).

@skipz: How about your calculation for LUN, let's say 164?

I expect

x/x/x/.x.x...1.4.4

I think that this method works for this particular problem (as per the output in the attachment). This post had something similar mentioned in regard to disk device file names: http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1091545 .

If solutions enabler is installed check with syminq -v . Inq utility also might show...

Hi All, Thank you. This will show you the lun id in hexadecimal.
#inq -nodots -clar_wwn .. but unable to find the lun id in 10.20.

See my first post:

0/2/0/0.97.4.19.0.1.0 LUN 8

====================^

Take the last "0" and convert into 3 digit binary:

000

then take the "1" and convert too:

0001 000 ==> 0001000bin = 8 dec

This is decimal 8 = LUN 8.
