Cause

綁定憑據不正確，因此 XMS 無法以綁定使用者身份進行角色或組查找。

 

Resolution

更正綁定憑據：繫結名稱或繫結密碼

針對 XMS 版本 6.XXX 上的陣列，KB 文章 29438 中顯示的特定特殊字元：XtremIO：使用 WebUI 設定繫結密碼時，不允許使用無效的 ASCII 字元用於基礎結構驗證。

使用 XMCLI （XMS 的命令列） 設定綁定密碼時，不存在相同的特殊字元限制。但是，若使用上述任何特殊字元修改密碼，確實會使 XMS Recovery 在以後需要時無法運作，包括新 XMS 取代舊 XMS 的情況。強烈建議您在修改綁定密碼時使用 WebUI。只有在避免上述 KB 中提到的字元時，才應使用 XMCLI 方法來修改密碼。
