First read perllol (list of lists).
I assume you want to use the physical volumes as a key in your hash.
Them why do you first put a hashref in the hash, and a list in that hashref.
This should work:
push @{$pvolumes{$pv} }, "$lv:$lp:$pp:$dist";
i assume the scalar "$lv:$lp:$pp:$dist" represents 1 logical volume and
this stament is in a loop.
