Major Cable_tamper
Controller Node-02 has only a single-path configuration to disk shelf 2.10.
This might occur when the controller does not have dual-path configuration to stack 2, a SAS HBA port on the controller connected to the disk shelf is disabled, or shelf-to-shelf cabling is incorrect.
- Also, we observed that the system is in a mixed path.
