fence_lpar: #504705 - fence_lpar: lssyscfg command on HMC can take longer than SHELL_TIMEOUT
    
    The lssyscfg command issued to the HMC by fence_lpar to get the status of the
    LPAR can take longer than SHELL_TIMEOUT, 3 seconds.  This results in fencing
    failures which could be avoided if fence_lpar waited longer for the HMC to
    respond to the command.
