Hello,

I have a three dimensional hash with info like below.

%LPAR_config = (
                 'lpar1' => {
                                            'profile1' => { ...
                                                          },
                                            'profile2' => { ...
                                                          },
                                            'frame' => 'frame1',
                                            'lpar_id' => '1'
                           }
                'lpar2' => {
                                            'profile1' => { ...
                                                          },
                                            'profile2' => { ...
                                                          },
                                            'frame' => 'frame1',
                                            'lpar_id' => '2'
                'lpar3' => {
                                            'profile1' => { ...
                                                          },
                                            'profile2' => { ...
                                                          },
                                            'frame' => 'frame2',
                                            'lpar_id' => '1'
                           }
                'lpar4' => {
                                            'profile1' => { ...
                                                          },
                                            'profile2' => { ...
                                                          },
                                            'frame' => 'frame2',

I've skipped the original list, as it has 191 lpars and each a lot of info. At one point in the program I need to get the name of the lpar from frame2 with lpar_id 1.

I'm now looping trough the keys to check if the lpar with name $key is on frame "frame2" and has lpar_id 1.
As I can skip most of the entries I was wondering, is there an easier way to get the key based on the content of the values of $key

On a related note, is there an easy way (read without looping myself) to copy a subset of the hash (for example all lpars on frame2) to another hash? This would speed-up the script, as most data is needed of just 1 frame (of 14 available)
