如何根據事件日誌中報告的捲名辨識 WMI 中的捲?
我有一個報告以下錯誤的 Windows 2008R2 伺服器:
磁碟上的文件系統結構已損壞且無法使用。請在卷\Device\HarddiskVolume2上執行 chkdsk 實用程序。
使用 Powershell 和 WMI 如何在查詢時辨識這是哪個卷
Win32_Volume
。例如,如果我這樣做:
Get-WmiObject Win32_Volume
我得到了伺服器上所有捲的列表,但是沒有一個
Win32_Volume
類屬性使用(看起來是)這個“友好”名稱 -\Device\HarddiskVolume2
。我可以看到有一個DeviceID
屬性返回這樣的值:DeviceID : \\?\Volume{4bc3df2a-65c7-11e0-9c33-806e6f6e6963}\
還有一個
Name
屬性,但這只是分配給卷的驅動器號。其他任何屬性都沒有一個與事件日誌中報告的內容相近的值。我知道我可以解析輸出
fltmc volumes
或DISKPART
獲取此資訊,但必須有一種方法可以在 PowerShell 腳本中使用 WMI 來獲取此資訊。我還查看了
Win32_DiskDrive
,Win32_DiskPartition
和Win32_LogicalDisk
類,但沒有提到類似的屬性值\Device\HarddiskVolume2
。
看看這段程式碼: http: //poshcode.org/4768它似乎做了你需要的轉換來看看你想要什麼,你也許可以調整它以滿足你的需要,如果你需要幫助,請告訴我但我認為你可以自己弄清楚。
