Hi Kamal,

You cannot find out which all HDDs are coming under a lun.Its is decided by the VA internally.

Also if you wanna find out the LUN mappings you have to keep a track of it at the time of LUN and VG/LV creation. At my place I also faced the same problem but before it is getting messed up I created an excel file to keep the LUN mappings for VGs.

So if you have already created many luns and VGs with them -- sorry to say you its a bit difficult to collect the details.

TAIL:- Lun creation is happening in particular order , you can find the same from the following details and apply the same logic in your case too.

Below is my tracking sheet.


LUN Device file Name Server's Hostname VG Size(GB)

0 /c20t0d0 test1db vg01 10MB
1 /c20t0d1 test1db vg01 40
2 /c20t0d2 test1db vg01 40
3 /c20t0d3 test1db vg01 40
4 /c20t0d4 test1db vg01 40
5 /c20t0d5 test1db vg01 40
6 /c20t0d6 test1db vg01 40
7 /c20t0d7 test1db vg02 40
8 /c20t1d0 test1db vg02 40
9 /c20t1d1 test1db vg02 40
10 /c20t1d2 test1db vg02 40
11 /c20t1d3 test1db vg02 40
12 /c20t1d4 test1db vg02 40
