Hi,

Depending on if you are using 7-Mode or cDOT it's either Add-NaLunMap or Add-NcLunMap. See cmdlet help for usage:

PS C:\> get-help add-nclunmap -examples

NAME
    Add-NcLunMap

SYNOPSIS
    Maps a LUN to all the initiators in the specified initiator group.

    -------------- Example 1 --------------

    C:\PS>Add-NcLunMap /vol/testvol/testlun x3550rre8

    Map LUN 'testlun' to igroup 'x3550rre8'.

I am not sure why It keeps saying value cannot be null

get-nclunmap /vol/myvol/mylun

get-nclunmap : Value cannot be null.
Parameter name: Controller parameter neither specified nor set in $global:CurrentNcController
