Lower down usage high of paging space without reboot server (on aix 5.0 above )

1) Create a new same sized paging space with the old one, and when using smitty pgsp , select:
Start using this paging space NOW? yes
Use this paging space each time the system is RESTARTED? yes
2) Then deactivate the original paging space. It's better to use command, for example, if /dev/hd6 is the old paging
space, then
# nohup swapoff /dev/hd6 > /tmp/swapoff.log 2>&1 &
3) Before step 2 finish, check paging space usage, by:
# lsps -a
you will find the usage of new paging space growing gradually while the old one decreasing gradually.
4) Without waiting step 2 finish, change the original paging space (hd6) to
Use this paging space each time the system is RESTARTED? no
5) After it finishes, Activate the original paging space (hd6)
6) (Optional) Remove the original paging space. (leave it if you want to swap paging space next time)
