Question

跟进此问题（Cannot set SCOM maintenance mode remotely）

我们正试图远程将服务器置于维护模式。我正在使用由Tom Schumacher（https://gallery.technet.microsoft.com/scriptcenter/Put-server-in-Maintenance-0a23e1fe）创建的SCOM函数

我正在使用PSSession尝试从SCOM服务器以外的服务器将服务器置于维护模式：

. C:\Scripts\Start-serverScommaintenance.ps1
$s = New-PSSession -ComputerName scomserver
Invoke-Command -Session $s -Scriptblock {Import-Module OperationsManager}
Invoke-Command -Session $s -Scriptblock ${function:Start-
serverScommaintenance} 
Invoke-Command -Session $s -Scriptblock {Start-serverScommaintenance -
servername testserver -message "test" -maintmodeinMinutes '6'}

当我进入该功能时，我收到以下错误：

无法验证参数＆＃39; DisplayName＆＃39;的参数。参数为null或空。提供非null或空的参数，然后再次尝试该命令。 + CategoryInfo：InvalidData：（:) [Get-SCOMClassInstance]，ParameterBindingValidationException + FullyQualifiedErrorId：ParameterArgumentValidationError，Microsoft.SystemCenter.OperationsManagerV10.Commands.GetSCClassInstanceCommand + PSComputerName：scomserver

术语＆＃39; Start-serverScommaintenance＆＃39;不被识别为cmdlet，函数，脚本文件或可操作程序的名称。检查名称的拼写，或路径是否正确包含，验证路径是否正确，然后重试。 + CategoryInfo：ObjectNotFound：（Start-serverScommaintenance：String）[]，CommandNotFoundException + FullyQualifiedErrorId：CommandNotFoundException + PSComputerName：scomserver

以下是用于参考的函数的副本：

function Start-ServerScommaintenance
{
param([string] $servername = 'yourServerGoeshere',
   [string]$message = "Putting: $servername into Maintenance Mode via     automation",
   [int]$maintModeinMinutes = '60')

$funcName = 'func - Start-ServerScommaintenance:'
if(get-command -Name 'Get-SCOMClassInstance')
{
    $server = (Get-SCOMClassInstance -DisplayName "$servername*") | select -first 1 | select -ExpandProperty Displayname
    $scommanagementServers = (Get-SCOMManagementServer).displayName
    if($scommanagementServers -ccontains $server)
    {
        Write-Warning "$funcname contains a Management Server $server.. You cannot put a management server in Maintenance Mode!!!"
    }
    else
    {
        $time = ((get-date).AddMinutes($maintModeinMinutes))
        $serverClassIds = Get-SCOMClassInstance -DisplayName $server
        foreach($classid in $serverClassIds)
        {
            $server1 = Get-SCOMClassInstance -id ($classid.id) | Where-Object{$_.DisplayName -match $server}
            write-host "$funcName putting " ($server1.id) ' in maintenance Mode Servername -->' ($Server1.DisplayName)
            if(!(Get-SCOMMaintenanceMode -Instance $classid))
            {
                Start-SCOMMaintenanceMode -Instance $server1 -EndTime $time -reason PlannedOther -Comment $message
            }
            else
            { Write-host "$funcname " $classid.id " has already been placed in Maintenance Mode"}
        }
    }
}
    else
    { Write-host "$funcname doesn't have the Operationsmanager module imported for this session"}
}

function Stop-ServerScommaintenance
{
param([string] $servername = 'yourServerGoeshere',
   [string]$message = "Removing Maintenance Mode from: $servername via     automation"
   )
$funcName = 'func - Stop-ServerScommaintenance:'
if(get-command -Name 'Get-SCOMClassInstance')
{
    $server = (Get-SCOMClassInstance -DisplayName "$servername*") | select -    first 1 | select -ExpandProperty Displayname
    $scommanagementServers = (Get-SCOMManagementServer).displayName

    {

    }
    else
    {
        $serverClassIds = Get-SCOMClassInstance -DisplayName $server
        foreach($classid in $serverClassIds)
        {
            $server1 = Get-SCOMClassInstance -id ($classid.id) | Where-    Object{$_.DisplayName -match $server}
            write-host "$funcName removing " ($server1.id) ' in maintenance     Mode Servername -->' ($Server1.DisplayName)
            $result = (Get-SCOMClassInstance -id ($classid.id)|Where-Object{$_.Displayname -like $servername}).StopMaintenanceMode((get-date).ToUniversalTime())
        }
    }
}
else
{ Write-host "$funcname doesn't have the Operationsmanager module imported for this session"}
}
#Start-serverScommaintenance -servername Server1 -message "my message" -maintmodeinMinutes '30' 
#Stop-ServerScommaintenance -servername Server1 -message "my message"

我相信你需要在使用函数时传递带有参数列表的东西，而不是用args再次调用函数：

Invoke-Command -Session $s -Scriptblock ${function:Start-serverScommaintenance} -argumentlist #argshere
