If I run lparstat on an AIX LPAR on a JS22 blade, I don't see the "app" field:

# lparstat

System configuration: type=Shared mode=Uncapped smt=On lcpu=4 mem=4096MB

psize=4 ent=0.20

%user %sys %wait %idle physc %entc lbusy vcsw phint

----- ----- ------ ------ ----- ----- ------ ----- -----

72.9 19.7 0.1 7.4 0.00 1.0 1.4 219822533 267118

I'd like to see the "app" field. The "app" value tells me my "available physical processors (app) in the shared pool" stat's.

Normally, I would change the LPAR properties via the HMC and tick the "Allow performance information collection" box. However, I couldn't find something like this in LPAR properties on the JS22.

Here's the solution

- Create a text file with the following contents:

$ cat myfile

name=mylpar1,allow_perf_collection=1

- Run the following command to change to the LPARs attributes.

$ lssyscfg -r lpar -F name,allow_perf_collection

myvios,0

mylpar1,0

$ chsyscfg -r lpar -f myfile

$ lssyscfg -r lpar -F name,allow_perf_collection

myvios,0

mylpar1,1

$ lparstat

System configuration: type=Shared mode=Uncapped smt=On lcpu=4 mem=4096MB psize=4 ent=0.20

%user %sys %wait %idle physc %entc lbusy app vcsw phint
