回應降級系統健全狀況的範例

07/31/2023 貢獻者

藉由檢閱缺少兩條節點路徑的機櫃所造成的降級系統健全狀況的特定範例、您可以查看當回應警示時CLI顯示的內容。

啟動ONTAP 功能後、您會檢查系統健全狀況、發現狀態已降級：

      cluster1::>system health status show
        Status
        ---------------
        degraded

您會顯示警示、以瞭解問題所在位置、並看到機櫃2沒有兩個節點1路徑：

      cluster1::>system health alert show
               Node: node1
           Resource: Shelf ID 2
           Severity: Major
	   Indication Time: Mon Nov 10 16:48:12 2013
     Probable Cause: Disk shelf 2 does not have two paths to controller
                     node1.
    Possible Effect: Access to disk shelf 2 via controller node1 will be
                     lost with a single hardware component failure (e.g.
                     cable, HBA, or IOM failure).
 Corrective Actions: 1. Halt controller node1 and all controllers attached to disk shelf 2.
                     2. Connect disk shelf 2 to controller node1 via two paths following the rules in the Universal SAS and ACP Cabling Guide.
                     3. Reboot the halted controllers.
                     4. Contact support personnel if the alert persists.

您可以顯示警示的詳細資料、以取得更多資訊、包括警示ID：

      cluster1::>system health alert show -monitor node-connect -alert-id DualPathToDiskShelf_Alert -instance
                  Node: node1
               Monitor: node-connect
              Alert ID: DualPathToDiskShelf_Alert
     Alerting Resource: 50:05:0c:c1:02:00:0f:02
             Subsystem: SAS-connect
       Indication Time: Mon Mar 21 10:26:38 2011
    Perceived Severity: Major
        Probable Cause: Connection_establishment_error
           Description: Disk shelf 2 does not have two paths to controller node1.
    Corrective Actions: 1. Halt controller node1 and all controllers attached to disk shelf 2.
                        2. Connect disk shelf 2 to controller node1 via two paths following the rules in the Universal SAS and ACP Cabling Guide.
                        3. Reboot the halted controllers.
                        4. Contact support personnel if the alert persists.
       Possible Effect: Access to disk shelf 2 via controller node1 will be lost with a single
 hardware component failure (e.g. cable, HBA, or IOM failure).
           Acknowledge: false
              Suppress: false
                Policy: DualPathToDiskShelf_Policy
          Acknowledger: -
            Suppressor: -
Additional Information: Shelf uuid: 50:05:0c:c1:02:00:0f:02
                        Shelf id: 2
                        Shelf Name: 4d.shelf2
                        Number of Paths: 1
                        Number of Disks: 6
                        Adapter connected to IOMA:
                        Adapter connected to IOMB: 4d
Alerting Resource Name: Shelf ID 2

您認可警示、表示您正在處理警示。

      cluster1::>system health alert modify -node node1 -alert-id DualPathToDiskShelf_Alert -acknowledge true

您可以修復機櫃2和節點1之間的纜線、然後重新啟動系統。然後再次檢查系統健全狀況、並查看狀態 OK：

      cluster1::>system health status show
        Status
        ---------------
        OK
