paging space

UNIX AIX
1

Hello everyone

I have a doubt about how many paging space can have in the same disk.

lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type
paging00 hdisk0 rootvg 3072MB 1 yes yes lv
hd6 hdisk0 rootvg 3072MB 1 yes yes lv

The best option its that I create only one. Then In this example I need to remove paging00.

Thanks for yours tips.

If you want to remove the paging space "paging00" follow the instructions for removing a paging space from the AIX Infocenter. You can find that easily by searching for "remove paging space AIX" in google (which is, btw. your friend, my friend).

Consult the man pages for the "swapoff", "rmps", "swapon" and "chps" commands to learn more about managing paging space in AIX.

I hope that helps.

Thanks for the reply bakunin.

My question is about how many paging space can I have in the rootvg

In the example in x partition I have two.

Is this ok. or I need to have only one hd6 with more paging space but only one.

I hope you get the idea about my question.

Thanks again

it doesn't hurt to have a couple paging spaces, but if they are on the same disk it doesn't really help either. I generally keep one paging space unless it's on older systems with small disks and we have at least 3 or more disks in rootvg. Then I will will create 2 mirrored paging spaces to spread the activity across several disks.

As far as your original question if there is a limit, I do not know.

Also, if you have multiples make sure that they are all the same size.

you can use the command

lsps -a

to show paging utilization
