You usually enter the SYSMAN IO SCSI_PATH_VERIFY command
    after performing an online reconfiguration of a SCSI or an
    FC interconnect. The command reads the device type and device
    identifier on each SCSI and FC path in the system. If the device
    does not match the data stored in the IO database, then the path
    is disconnected in the IO database. Following a SYSMAN IO SCSI_
    PATH_VERIFY command, you usually enter a SYSMAN IO AUTOCONFIGURE
    command, which updates the IO database to match the new SCSI or
    FC configuration.
