Checking the HyperMetro

Cause 1: The link of the active-active remote device is abnormal. see Checking the Status of a Remote Replication.
Cause 2: Link Status of the quorum server is Link Down.
1. Check whether the cabling is normal.
  - Cables are removed => reinsert the cables
    Then run the show quorum_server_link general command on CLI to check whether Link Status is Link Up. If yes, no further operation is required. If no, replace cables.
  - Cables are damaged => replace the cables. Then run the show quorum_server_link general command on CLI to check whether Link Status is Link Up. If yes, no further operation is required, If no, go to 2.
  - Yes => 2.
2. Check whether the quorum server is normal.
  - No => Troubleshoot the fault.
