Impact on the System

The availability of HyperMetro third-party arbitration cannot be ensured, and the storage system reliability decreases.

Possible Causes

  • Links are down.
  • Links are unstable.
  • The quorum server is faulty.
  • Arbitration service ports are disabled on the quorum server's firewall.
  • The arbitration certificate of HyperMetro is invalid.


  1. Check whether the link is normal.

    1. If yes=> Step2.
    2. If no, replace the faulty network cable to ensure that the link works correctly. If the alarm persists=> Step2.

  1. Check whether the quorum server IP address is reachable.

    1. If yes=> Step3.
    2. If no, check communication network configurations, and ensure that the quorum server IP address is reachable. If the alarm persists=> Step3.

  2. Check whether arbitration service ports are enabled on the firewall of the quorum server.

    1. If yes=> Step4.
    2. If no, enable the arbitration service port to ensure that arbitration packets can pass through the firewall. The service port is 30002 by default. If the alarm persists=> Step4.

  3. Check whether an alarm is reported indicating that the HyperMetro quorum certificate on the storage array is invalid.

    1. If yes, handle the alarm by taking recommended actions. If the alarm persists=> Step5.
    2. If no=> Step5.

  4. Run show tls_cert on the service port of the quorum server to check whether the certificate is valid.

    1. If yes=> Step6.
    2. If no, run export tls_cert to export the certificate, and request for a CA-signed certificate. Run import tls_cert to import the obtained CA certificate and the application certificate. If the alarm persists=> Step6.

  5. Check whether the quorum server is working correctly.

    1. If yes=> Step7.
    2. If no, check the running state of the quorum server process, and ensure that the quorum server process is running correctly. If the alarm persists=> Step7.

  6. Collect related information and contact technical support engineers.
