Identify ONTAP LUN on Windows host

Hi all,

 

I give up, I'll never be a Windows guy.

 

Please enlighten me: With no SnapDrive on board, how is it possible to identify the name of an iSCSI LUN on an ONTAP 9 filer?

 

I tried to match any sort of number from the outputs of

 

::> lun mapping show

::> lun show

and

::> iscsi session show

 

with the outputs of

 

PS C:\Users\admin> iscsicli

and

PS C:\Users\admin> Get-IscsiConnection

 

 

to no avail.

 

All I want is to find the name of the LUN/volume on Windows to find the corresponding object on the filer to modify.

 

 

Any clues?

 

Thanks and best regards

 

Peter

Have you tried the MicroSoft iSCSI initiator utility in Windows. This should give you the LUN ID

I have, yes. Unfortunately LUN ID reported by Windows doesn't match the LUN ID on the NetApp side.

 

But thanks for the info.

Using native MPIO you can find the serial number with something like `mplcaim -v mpio.txt`.  Pop open mpio.txt to find the SN, and you should be able to match that up with the output of `lun show -fields serial-hex` on the filer.  Match up the MPIO disks to system disks with `mpclaim -s -d`.

Yeah, that's it! Cheers.
