4. Select Enable/Disable at System Restart
5. Choose Yes and press ENTER.
6. Quit smitty.
7. bosboot -ad /dev/ipldevice
8. shutdown -Fr
9. bootinfo -K (should now show 64)

Paging Space in AIX
System paging space
#lsps -a --
current utilization of each of the paging spaces on a system
lsps -s -------
total active paging space and its current utilization.
swapon---- to activate the initial paging-space device.
swapoff
--command to dynamically deactivate the paging space,
swapon -a
---Activates listed in the /etc/swapspaces
Creating paginglv-----
smit mklv
eg: Name-------paging03
On
---------------------hdisk5
VG
--------------------rootvg
b) swapon
/dev/paging03-----To activate paging
Increasing and decreasing paginglv
Use the chps -d
command to decrease the size of paging03 by 2 logical partitions
# chps -d 2
paging03
To increase
#chps –s 2
paging03
