Time resolving virtualized partition memory page faults :
42319894851.80

System Info :

IBM P570 with 8 CPU

two of my vio servers do the same thing:

What is that doing? I can't find anything about it on the web.

Hmmm

My VIOS have none:

/home/padmin >vmstat -v
131072 memory pages
117315 lruable pages
19187 free pages

75345 pinned pages

Could you please issue the following command in your VIOS ??

lsps -a

just to check if there's paging activity.

Here's mine:
viob1:/home/padmin:# lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type
paging00 hdisk0 rootvg 1024MB 9 yes yes lv
hd6 hdisk0 rootvg 512MB 17 yes yes lv
viob1:/home/padmin:#

[kah00na]

better spacing:

viob1:/home/padmin:# lsps -a
Page Space      Physical Volume   Volume Group    Size %Used Active  Auto  Type
paging00        hdisk0            rootvg        1024MB     9   yes   yes    lv
hd6             hdisk0            rootvg         512MB    17   yes   yes    lv
viob1:/home/padmin:#

I have a total of 6 vio servers and only 2 of them are doing this.

I think I sized it well with 1 gig memory. All my VIOs are configured the same.

viob1:/home/padmin:# lparstat

System configuration: type=Shared mode=Uncapped smt=On lcpu=6 mem=1024 psize=8 ent=0.30

Hi

I wouldn't use two paging space devices on the same hdisk. I think you should identify the primary paging space (usually hd6) and make it bigger, then delete paging00.

With 1GB RAM i would use 4GB paging space and tune my system to free as much memory as it can to be used by the Shared Ethernet Adapter functions (if configured).

Please post the output of:

vmo -a | egrep "maxperm|minperm|maxclient"

and please post once again the putput of:

vmstat -v

Thanks
