Symptoms

使用者在嘗試建立磁碟區時，會在控制器驅動程式記錄中看到下列錯誤。具象狀態傳輸 （REST） 命令會擷取 SG 的詳細資料。REST 回應為「200 OK」，但記錄會在記錄中顯示「找不到儲存群組」。

然後繼續，REST 在嘗試創建卷之前檢查卷是否存在。REST 會傳回找不到磁碟區，並顯示 404 Not Found。但代碼需要一個空清單。

然後重複此行為，並且永遠不會創建卷。

Cause

使用者在進入 PowerMax 端點的 Unisphere 時，在值檔案或 powermax-reverseproxy-config 和 powermax-array-config 組態圖中新增了一個尾隨的「/」。

https://primary-1.unisphe.re:8443/

提供的值 YAML 檔在示例中沒有顯示尾隨“/”。

https://primary-1.unisphe.re:8443

 

Resolution

安裝應使用不包含附加“/”的值檔。

請參閱說明文件，並依照適用於特定環境的部署指示操作： https://dell.github.io/csm-docs/
 

Additional Information

若要在記錄中查看 POWERMAX HTTP 要求或回應，請啟用 powerMaxDebug：

請參閱說明文件，並依照適用於特定環境的部署指示操作： https://dell.github.io/csm-docs/

logLevel - CSI 驅動程式記錄層級。允許的值：「error」、「warn」/「warning」、「info」、「debug」
powerMaxDebug - 啟用 CSI 驅動程式與 Unisphere 之間的低層級和 HTTP 流量記錄。除非支援小組要求，否則請勿啟用此功能。
