嘗試將 SDS 上的新裝置新增至 VxFlex 作業系統
客戶嘗試將新裝置新增至 SDS,但收到錯誤
以下是新增裝置時,MDM 追蹤記錄中的錯誤:

Cause
聚焦於「超過時間預算」事件,此裝置似乎速度太慢,無法新增,或是硬體問題,可能是控制器問題或上述磁碟上的損壞磁區。
作為測試階段的一部分,添加新設備時,SIO 必須能夠在 ~4.5 秒內寫入 ~200 MB 的數據。可能是因為控制器問題或裝置的損毀磁區,或問題似乎是磁碟太慢,當我們看到錯誤「超出時間預算」並IO_HARD_ERROR
Resolution
這不是 VxFlex 作業系統的問題。這更像是硬體問題。
必須與硬體廠商接洽以進行調查。
1.檢查 RAID 控制器是否有問題。
2.檢查磁碟是否有問題,或是慢速磁碟。
3.如果可能,請嘗試獲取另一個磁碟並添加它。如果成功新增新磁碟,則表示先前的磁碟發生問題。
4. 如果新增至 SDS 時有多個新磁碟遇到相同的問題,請檢查 Raid 控制器上的問題。此外,請確定 RAID 控制器驅動程式/韌體為支援的版本。
