Error description

  • The user created a virtual system pattern that would use all the
CPU available. They then added a scaling policy to ensure that
it would scale up. The scaling operation never occurred and the
logs contained the following messages:


app.scripts.groovy.rainmaker.instances.
   VirtualMachineStatusUpdates.groovy run
   java.lang.RuntimeException:
java.util.concurrent.ExecutionException:
 com.ibm.iaas.api.client.exception.MaestroRestException:
 CWZIP2052E Unable to increase CPU when the virtual machine is
 running as current CPU count is 9 and hot-add is disabled.
groovy.rainmaker.instances.VirtualMachineStatusUpdates
 .run(VirtualMachineStatusUpdates.groovy:556)
groovy.rainmaker.core.EventUtils._fire(EventUtils.groovy:129)

Local fix

  • 



Problem summary


    

  • Usually if the maximum virtual CPU has been reached, a message
is displayed indicating that scale-out is not possible. The
maximun virtual CPU value for Linux systems is 8. In this
case the initial virtual CPU was 8, the same as the maximum
virtual CPU, and the message was not being displayed.

    



Problem conclusion


    

  • A code fix is being provided in PureApplication System
version 2.1.2.0 in the Foundation Pattern Type version
2.1.5.0.
