Powershell - 如何讓我的 PSCustomObject 顯示兩個輸出

凱爾·傑克·丹尼爾斯

我有以下腳本：

$DISKPhysical = Get-PhysicalDisk
$DiskErrors = Get-Disk | Get-StorageReliabilityCounter

    $DiskResults = [PSCustomObject]@{
    
        'Device ID' = $DISKPhysical.DeviceID
        'Model' = $DISKPhysical.Model
        'Serial Number' = $DISKPhysical.SerialNumber
        'Connector Type' = $DISKPhysical.BusType
        'Disk Type' = $DISKPhysical.MediaType
        'Health Status' = $DISKPhysical.HealthStatus
        'Size' = '{0:n0} GB' -f ($DISKPhysical.size/1GB)
        'PowerOnHours' = $DiskErrors.PowerOnHours
        'Read Errors' = $DiskErrors.ReadErrorsUncorrected
        'Wear' = $DiskErrors.Wear
        'Temperature' = $DiskErrors.Temperature
    }

$DiskResults | ConvertTo-JSON

如果只有 1 個“物理磁盤”，則當前返回信息。

{
    "Device ID":  "0",
    "Model":  "Micron_1100_MTFDDAK256TBN",
    "Serial Number":  "18301DD5EF41",
    "Connector Type":  "SATA",
    "Disk Type":  "SSD",
    "Health Status":  "Healthy",
    "Size":  "238 GB",
    "PowerOnHours":  895,
    "Read Errors":  0,
    "Wear":  0,
    "Temperature":  26
}

但是，當我有 2 個或更多物理磁盤（如 USB 記憶棒）時，出現以下錯誤：

Method invocation failed because [System.Object[]] does not contain a method named 'op_Division'.
At line:4 char:5
+     $DiskResults = [PSCustomObject]@{
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (op_Division:String) [], RuntimeException
    + FullyQualifiedErrorId : MethodNotFound

我知道這是因為 PSCustomObject 只返回第一個值，我如何讓它返回多個設備，如下所示：

{
    "Device ID":  "0",
    "Model":  "Micron_1100_MTFDDAK256TBN",
    "Serial Number":  "123456789",
    "Connector Type":  "SATA",
    "Disk Type":  "SSD",
    "Health Status":  "Healthy",
    "Size":  "238 GB",
    "PowerOnHours":  895,
    "Read Errors":  0,
    "Wear":  0,
    "Temperature":  26
},
{
    "Device ID":  "1",
    "Model":  "Cruzer Edge",
    "Serial Number":  "123456789",
    "Connector Type":  "USB",
    "Disk Type":  "Unspecified",
    "Health Status":  "Healthy",
    "Size":  "30 GB",
    "PowerOnHours":  null,
    "Read Errors":  null,
    "Wear":  0,
    "Temperature":  0
}

提前致謝，凱爾

通過管道將輸出從Get-PhysicalDisk到ForEach-Object：

$DiskResults = Get-PhysicalDisk |ForEach-Object {
    # Fetch operational details only for this disk
    $DiskErrors = Get-Disk -UniqueId $_.UniqueId | Get-StorageReliabilityCounter

    [PSCustomObject]@{
        'Device ID' = $_.DeviceID
        'Model' = $_.Model
        'Serial Number' = $_.SerialNumber
        'Connector Type' = $_.BusType
        'Disk Type' = $_.MediaType
        'Health Status' = $_.HealthStatus
        'Size' = '{0:n0} GB' -f ($_.size/1GB)
        'PowerOnHours' = $DiskErrors.PowerOnHours
        'Read Errors' = $DiskErrors.ReadErrorsUncorrected
        'Wear' = $DiskErrors.Wear
        'Temperature' = $DiskErrors.Temperature
    }
}
