Error description

  • When a  customer run the following in a version
    WPAR such as 5.2 or 5.3. The disk in the kernel
    will not have the queue depth set in kernel.
    
    1. chdev -P -l hdisk5 -a queue_depth=8
    2.  odmget CuAt | grep -p hdisk5 | less
    
    CuAt:
          name = "hdisk5"
          attribute = "queue_depth"
          value = "8"
          type = "R"
          generic = "UD"
          rep = "nr"
          nls_index = 30
    
    3.  stopwpar -N <wpar_name>
    
    The customer then will see that the performance
    is still the same. When a perfpmr is sent in
    from the global lpar you will see that the
    queue_depth is set to 1 for all of the disk
    exported to the wpar.
