arrays - 如何从远程 pssession 获取变量输出

Question

我有一个从 vmm 获取虚拟硬盘信息的脚本，我从服务器远程执行它，目前我无法在本地主机的 pssession 之外获取变量值，请你帮我实现同样的目标。

PS C:\Windows\system32> enter-pssession iscvmm02
[iscvmm02]: PS C:\Users\su\Documents>Add-PSSnapin Microsoft.SystemCenter.VirtualMachineManager
[iscvmm02]: PS C:\Users\su\Documents>$hide= Get-VMMServer -ComputerName "iscvmm02.corp.avanade.org"
[iscvmm02]: PS C:\Users\su\Documents>$VM = Get-VM | where { $_.ComputerNameString -contains "idpsm02.corp.air.org" }
[iscvmm02]: PS C:\Users\su\Documents>$harddisk=$VM.VirtualHardDisks
[iscvmm02]: PS C:\Users\su\Documents>$h=$harddisk.length
[iscvmm02]: PS C:\Users\su\Documents>for($i=0;$i-lt$h;$i++){
    New-Variable -Name "HardDiskType_$i" -value $harddisk[$i].vhdtype
    New-Variable -Name "HardDiskLocation_$i" -value $harddisk[$i].Location
}
[iadpscvmm02]: PS C:\Users\su\Documents>Exit-PSSession
PS C:\Windows\system32>$harddisktype_0
PS C:\Windows\system32>$harddisklocation_0

如您所见，变量输出都给出空值，我无法保留这些值

此示例从远程计算机的 C 驱动器获取列表并将其分配给本地变量。因此，相应地调整您的 VMM 脚本。

$session = New-PSSession -ComputerName RemoteSystem
Invoke-Command -Session $session -ScriptBlock { $remoteC = gci c:\ }
# This shouldn't print anything.
$localC
# Print the result on remote computer an assing its output to localC variable
$localC = Invoke-Command -Session $session  -ScriptBlock { $remoteC }
# Print the local variable, it should contain remoteC data.
$localC
