    CMAN: scsi_reserve should handle multipath with partitions
    
    When using dm-multipath with a LUN has parititions, the dm device's
    slaves are nested. The script should recongize this scenario and
    correctly find the device's slaves. Also fixed incorrect variable
    name and uncommented the 'fence_tool leave' command.
