If I ask you this questions, it's to see if you must add a new Paging space.
Because the best is to use the real memory instead of paging space.
To add a new paging space, smit, 'System Storage Management', 'Logical Volume manager', 'Paging Space', 'Add another paging space'. For the size, you must put the same like the others.
To change the location 'inner, middle', you have to modify the logical volume
smit , 'System Storage Management', 'Logical Volume manager', 'Logical Volume', 'Set Characteristic ...', 'Change of Logical Volume'.
Si your paging space named hd6, to see the location of it, do
lslv -l hd6 |
