An SVF System Failed to Be Set Up

An SVF System Failed to Be Set Up

Common Causes

This fault is commonly caused by the following:
  • Configurations are incorrect.

  • Links become faulty.

Troubleshooting Flowchart

The troubleshooting roadmap is as follows:
  • Run the display stack configuration command to check the SVF configuration.
  • Run the display stack troubleshooting command to check SVF failure events.
  • Check whether links are faulty.

Troubleshooting Procedure

  • Saving the results of each troubleshooting step is recommended. If your troubleshooting fails to correct the fault, you will have a record of your actions to provide technical support personnel.

  • The following procedures can be performed in any sequence.

  • The command outputs in the following procedures vary according to the device model and version. The following procedures provide methods to view related information.

  1. Run the display stack configuration command to check whether the SVF configuration is correct.

    102           Auto(Auto)         4*10GE(4*10GE)
    -------------------------------------------------
    

    In the command output, the Oper(Conf) field indicates the current configuration and next startup configuration.

    • Check whether the member ID of the parent switch is less than or equal to 4. When setting up an SVF system of fixed switches, the parent switch must have a stack member ID that is less than or equal to 4.

    • Check whether the parent switch has a stack domain configured. When setting up an SVF system of fixed switches, the parent switch must have a stack domain configured. If the parent switch is a stack of two member devices, the two member devices must have the same stack domain configured.

    • Check whether fabric ports are bound to leaf IDs (indicated by the BindMember field).

    • Check whether the leaf switch mode (indicated by the Switch Mode field) is Auto or Leaf.

  2. Run the display stack troubleshooting command to check failure events occurring during SVF system setup.

    This command displays information about failures occurring during SVF system setup so that you can troubleshoot the failures according to the information.

    --------------------------------------------------------------------------------
    
  3. Check whether links are faulty.

    Run the display interface fabric-port [ port-id ] command to check whether the physical status and protocol status of the fabric port and its member ports are Up. If not, check whether optical modules and fibers are faulty.

  4. Collect the following information and contact technical support personnel:

    • Results of the preceding troubleshooting procedure
    • Configuration file, logs, and alarms of the device
