The SYSMAN IO FIND_WWID command probes all Fibre Channel ports,
    detects all previously undiscovered tapes and medium changers
    behind a Network Storage Router (NSR) or a Modular Data Router
    (MDR), and assigns a worldwide identifier (WWID) to each one.

    The command also displays a list of the devices and their
    assigned device names and automatically records this information
    in the SYS$SYSTEM:SYS$DEVICES.DAT file. Finally, the command
    updates relevant local and clusterwide memory structures.

    To configure newly attached Fibre Channel tapes, use this command
    prior to running the SYSMAN command IO AUTOCONFIGURE.

    You must have CMKRNL privilege to use the SYSMAN IO FIND_WWID
    command.

    For more information about Fibre Channel, see the Guidelines for
    OpenVMS Cluster Configurations.
