There was a formatting problem in the old message. The actual message was :
Run "dfm vfiler list <vfiler_name>" in CLI to view the corresponding Hosting storage system. If you want to view the Hosting Storage system for all the vFilers, run "dfm vfiler list". In Web UI, you need to launch the "vFilers, All" report which can be launched by "Home -> Member Details ->
I struggled with this when I ran vfilers as well. I had a script that would connect to all the physical heads, do a vfiler status, and grep for the vfiler I was looking for. If your environment is so big that looping through all the controllers isn't really feasible, you could do something like have a cron job nightly gather the info and store it somewhere, then you could just check that source.
the command "filer> ssh filername vfiler status " gives the vfiler list associated with that filer .
Try to create a script which will take vfiler name as input and will run the above command for all the filers once run .
and then vfiler name string will see in which vfiler status command its name is comming in output .Try to print the 'filername' from the desired vfiler status command at console .Scripting is the only way to resolve this issue
