No, because a value in a hash (anonymous or not) is a scalar - which can be an array reference, of course. So, judging from your data, the correct idiom would be

    my @cmdarr = @{$server->{"cmds"}};
[download]

For me, it is much simpler to de-reference references with the -> notation, so I would write

    $server->{"cmds"}->[$i]->{status}

instead of

    $$server{"cmds"}[$i]{status}
[download]

What does your csv2hash function return? A list or a reference? Check that, it could be the cause of "Reference found where even-sized list expected ...".
