如何根據磁盤路徑確定數據存儲？

Question

任何vmware powershell人都在那裏？我希望有人能幫助我。有沒有簡單的方法向我展示服務器上連接磁盤的驅動器標籤以及該磁盤所在的數據存儲區？例如，我們現在有一個名爲'SQL01 \ Tlog'的安裝點的SQL Server，我現在該如何找到該磁盤所在的數據存儲？ 此命令顯示每個磁盤的路徑： （get-vm Computername）.Guest.Disks 此命令顯示服務器上的數據存儲： get-vm Computername | Get-Datastore 我該怎麼做才能看到數據存儲的路徑呢？

在過去，我不得不以可靠的方式將虛擬機的虛擬磁盤與操作系統的磁盤進行匹配。假設虛擬機配置中的第一個磁盤是操作系統中的第一個磁盤是不安全的。下面的方法首先嚐試匹配基於序列號的磁盤。如果失敗，它也會嘗試匹配SCSI目標ID。其給出的主機名和虛擬機的名稱爲$ CN計算機...

#define the computer & VM name 
$CN = 'mycomputer' 

#get OS disk information 
$GWOsplat = ` 
    @{computername = $CN 
    class = 'win32_diskdrive' 
    erroraction = [system.management.automation.actionpreference]::stop} 
$OSdisk = get-WMIobject @GWOsplat 

#get VM disk information 
$GVsplat = ` 
    @{viewtype = ([VMware.VIM.virtualmachine]) 
    filter = @{name="^$CN`$"} 
    property = @('name','config.hardware.device') 
    erroraction = [system.management.automation.actionpreference]::stop} 
$VM = get-view @GVsplat 
$VMdisk = $VM.config.hardware.device | where-object {$_.deviceinfo.label -like 'hard disk*'} 

#get the number of SCSI controllers 
$controllercount = ($VMdisk.controllerkey | group-object | measure-object).count 

#iterate through VM disks 
foreach($VMD in $VMdisk) 
{ 
    #get VM disk serial number and SCSI target ID 
    $VMDSN = $VMD.backing.UUID -replace '-','' 
    $VMDSID = $VMD.unitnumber 

    #iterate through operating system disks 
    foreach($OSD in $OSdisk) 
    { 
    #get OS disk serial number and SCSI target ID 
    $OSDSN = $OSD.serialnumber 
    $OSDSID = $OSD.SCSItargetID 
    if(($VMDSN -eq $OSDSN) -or (($controllercount -eq 1) -and ($VMDSID -eq $OSDSID))) 
    { 
     #matching OSdisk found 

     #get datastore 
     $DS = get-datastore -ID $VMD.backing.datastore 

     #get partitions within OSdisk 
     $GWOsplat = ` 
     @{computername = $CN 
     query = "associators of {win32_diskdrive.deviceID='$($OSD.deviceID)'} WHERE resultrole=dependent" 
     erroraction = [system.management.automation.actionpreference]::stop} 
     $partition = get-WMIobject @GWOsplat 

     #get logicaldisks within partitions 
     foreach($P in $partition) 
     { 
     $GWOsplat = ` 
      @{computername = $CN 
      query = "associators of {win32_diskpartition.deviceID='$($P.deviceID)'} WHERE resultrole=dependent" 
      erroraction = [system.management.automation.actionpreference]::stop} 
     $logicaldisk = get-WMIobject @GWOsplat 

     #output custom object mapping drive letter to datastore 
     foreach($LD in $logicaldisk) 
     { 
      [PScustomobject] ` 
      @{computername = $CN 
      datastore = $DS 
      drive = $LD.deviceID} 
     } 
     } 
     break 
    } 
    } 
} 

的原因，我只嘗試SCSI目標ID匹配，如果有一個SCSI控制器是我無法找到一個可靠的方式來匹配SCSI使用虛擬機的SCSI控制器在操作系統中控制器。它應該是一個非常小的缺點，因爲大多數磁盤將在序列號上匹配，並且大多數虛擬機沒有多個SCSI控制器。下面

是2層的功能， 「基團的volumedisk」 和 「基團的VMOSdisk」。我沒有完全評論他們，但他們確實有一些評論，而且他們相當直接。

group-VMOSdisk使用group-volumedisk獲取計算機的win32_volume實例到它的win32_diskdrive實例的映射。 group-VMOSdisk主要是這篇文章第一部分的內容。

連接到您的vSphere服務器，然後將$ CN連接到group-VMOSdisk。
