wlm configuration

Joy_S — Thu, 06 Dec 2007 00:07:47 GMT

Hello ;

I am trying to use WLM ver.3.2 with vpars ver.4 on hpux 11.31 , I used samples par_usage_goal.wlm, par_usage_goal.wlmpar and followed instructions, after activating the WLM on all vpars in npar , I used "wlminfo slo -v" to monitor status , and found status "PASS" but when CPU utilization reach 100% , wlminfo show FAILED status ! ,and number of cores remain the same , how can I make inactive CPUs to be used ?

currently implement wlm on one complex 128-way , on one vpar I activated both daemons

wlmd -a wlmconf.wlm
wlmpard -a wlmconf.wlmpard

on other vpars in the complex I just activated
wlmd -a wlmconf.wlm

The conf files as below :
wlmconf.wlm
primary_host = vpar1;
tune {
wlm_interval = 5;
}
slo slo_vpar1 {

pri = 1;

goal = usage _CPU;
}

wlmconf.wlmpar
par {
interval = 10;
}

On the other vpars for example vpar2:

wlmconf.wlm
primary_host = vpar1;
tune {
wlm_interval = 5;
}
slo slo_vpar2 {

pri = 2;

goal = usage _CPU;
}

The above configuration activated without any problem , but when system workload reach 100% on CPU , wlm did not assign any free cpu to that
vpar and in " wlminfo slo -v " output under status , its moved from PASS to FAILED !

Can you please let me know what could be wrong with this configuration

Looking at the code you have mentioned below , does not sounds the thing you need is mentioned.

are you sure that is all (interval/priority/goal(CPU usage) suficent enough to do the online CPU asignment?

I am not worked on through this config....

I am not sure , this is my first time to configure WLM, do you mean I should use "utilitypri" in wlmconf.wlmpar file?
