      • Yes => The procedure is complete.
      • No => Cause 5.

  5. Cause 5: The port rate of the storage system is different from that of the device it is connected to.
    1. Check whether the network is a direct-connection network or a switch-connection network.

      • Switch-connection network => 5.b.
      • Direct-connection network => 5.h.

    2. Check whether the rates of the FC host port of the storage system and the switch port connecting to the storage system are the same.

      NOTE:

      For details on how to check the rate of a switch port or an FC HBA, consult relevant manufacturers or refer to relevant manuals.

    3. Adjust Running Rate of the FC host port to the same rate of the corresponding switch port.

Unavailable iSCSI Link

  1. Cause 1: The IP address of the iSCSI host port of the storage system or of the service network port of the application server is incorrect.
    1. Check whether the IP addresses of the iSCSI host port and that of the service network port can send and receive message to and from each other.

      • Yes => Keep the fault environment intact and contact technical support engineers.
      • No => 1.b.

    2. Check whether the network is a direct-connection network or a switch-connection network.

      • Switch-connection network => 1.d.

    3. Modify the IP address of the iSCSI host port to the same network segment as the IP address of the service network port, and then go to 1.e.

      NOTE:

      The IP address of the service network port can be modified to the same network segment as the IP address of the iSCSI host port.

    4. Add a route between the iSCSI host port and the service network port to enable the communication in between, and then go to 1.e.
    5. Run the ping command on the application server to check whether the network connection is established between the iSCSI host port and the service network port.

      • Yes => The procedure is complete.
      • No => Cause 2.

  2. Cause 2: Cables connecting the application server and the storage system are loose or damaged.
    1. Reinsert or replace the network cable connecting the storage system and the application server.

      • Yes => 2.c.
      • No => Keep the fault environment intact and contact technical support engineers.

    3. After the operation is complete, check whether the link indicator of the iSCSI host port is steady green, and whether its Running Status on the ISM is Link Up.
