[linux-lvm] possibly off-topic - multipath

[lejeczek]

.. but I thought I'd ask here for many profs are on this 
list here.

I'm just trying to use multipath - off topic - is it 
possible to configure group of devices/wwid in #multipaths { 
multipath ..# or each multipath can only be for a single wwid?

And will it be safe to have now VGs/LVs to migrate to 
multipath if they were created without it? Is such a 
"migration" even allowed, approved?

many thanks, L.
