• ヘルスアラートが次のエラーでアダプタを報告します：

cluster::>system health alert show
               Node: node-01
           Resource: 4d
           Severity: Major
    Indication Time: Sat Aug 15 13:05:58 2020
           Suppress: false
        Acknowledge: false
     Probable Cause: FC initiator adapter 4d is at fault.
    Possible Effect: Resiliency of backend storage is compromised.
 Corrective Actions: 1. Ensure that the FC initiator link has not been tampered with.
                     2. Verify the operational status of the FC initiator
                     adapter by using the command "system node run -node
                     local -command storage show adapter".
