    su - omm

    cd ${BIGDATA_HOME}/om-server/om/sbin/

  4. Run the sh status-oms.sh command, and execute the status-oms.sh script to check whether the floating IP address of the active FusionInsight Manager is normal. View the command output, locate the row where ResName is floatip, and check whether the following information is displayed.

    For example:

    10-10-10-160 floatip Normal Normal Single_active
    • If it is, go to 8.
    • If it is not, go to 5.

  5. Run the ifconfig command to check whether the NIC with the floating IP address exists.

    • If it does, go to 8.
    • If it does not, go to 6.

  6. Run the ifconfig NIC name Floating IPaddress netmask Subnet mask command to reconfigure the NIC with the floating IP address. (For example, ifconfig eth0 10.10.10.102 netmask 255.255.255.0).
