When the Physical Connection Is Changed Between NetApp FAS3000 Series/FAS6000 Series/FAS8000 Series/NetApp E Series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 and the Local Storage System, the Link Is Down

When the Physical Connection Is Changed Between NetApp FAS3000 Series/FAS6000 Series/FAS8000 Series/NetApp E Series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 and the Local Storage System, the Link Is Down

Symptom

NetApp FAS3000 series/FAS6000 series/FAS8000 series/NetApp E series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 is connected to the local storage system through a Fibre Channel switch. When the physical connection is changed (the optical fiber is connected to a different port of the switch or the optical fiber is moved from one port of the heterogeneous storage system to another) between the NetApp FAS3000 series/FAS6000 series/FAS8000 series/NetApp E series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 and the switch, the link cannot be detected on DeviceManager of the local storage system even though the physical connection works properly.

Possible Causes

NetApp FAS3000 series/FAS6000 series/FAS8000 series/NetApp E series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 automatically detects the status of the connection between its port and the local storage system port. If an inconsistency is found, NetApp FAS3000 series/FAS6000 series/FAS8000 series/NetApp E series/TOYOU iSUM780/iSUM850/Fujitsu DX100 S3/DX200 S3/DX500 S3/DX600 S3 refuses the connection, causing the link to become unreachable.

Procedure

  1. Remove and then insert the cable, or modify the port rate of the local storage system.

    NOTE:

    This operation is performed on the switch port where the fiber channel is connected.

  2. On DeviceManager of the local storage system, check whether the link can be detected.

    • If yes, no further action is required.
    • If no, keep the fault environment intact and contact Huawei technical support.
