Error description

  • After deploying a virtual system or virtual application pattern
    against an Environment Profile in an IBM PureApplication
    System, the user may observe a negative value in the
    "Environment limits" section, under the "In use" column of the
    the "Virtual CPU" row.
    

Local fix

Problem summary

  • If a virtual machine is reconfigured to increase the size of the
    virtual CPU count while the virtual machine is in STARTED
    state, the CPU in-use limit in the environment profile is not
    incremented to reflect the new size of the virtual CPU. This
    causes the CPU in-use limits to be incorrect.
    
    In some cases the CPU in-use limit may be negative as the value
    is decremented by the new size of the virtual CPU count when
    the virtual machine is stopped/destroyed. As a result of the
    incorrect CPU in-use limits, deployments exceeding the
    configured limits of the environment profile are not enforced
    correctly.
    

Problem conclusion

  • A virtual machine state of STARTED will not prevent the
    virtual CPU in-use value in the environment limits of the
    environment profile from being updated when the virtual CPU size
    of a VM is changed.
    
    It is important to note that existing environment profiles which
    contain incorrect values for current CPU in-use limit are not
    corrected by applying this APAR fix.
    
    The following additional actions are needed:
    
      1) Discontinue use of any existing environmental profiles with
         the incorrect values.
    
      2) Create a new environment profile to replace it.
    
      3) Redeploy the instances using the new environment profile.
