PowerShell工作流学习-4-工作流中重启计算机
关键点:
a)工作流中重新启动计算机,请使用Restart-Computer的Wait参数,Wait参数不仅适用于本地计算机,也适用于远程计算机。
b)重启运行工作流的计算机,手工恢复请使用Resume-Job,自动恢复请在运行工作流的计算机上创建计划任务、当工作流运行完成后注销该计划任务。
例a)
workflow Test-WFRestartServer { Param ( [string]$ServerName="localhost" ) Get-Process -Name WMSvc -PSComputerName $ServerName Restart-Computer -PSComputerName $ServerName -Wait Set-Content -Path "\\$ServerName\c\WFTest\1.txt" -Value 123 } ls '\\website14\c\WFTest\1.txt' Test-WFRestartServer -ServerName "website14" ls '\\website14\c\WFTest\1.txt' ls : 找不到路径“\\website14\c\WFTest\1.txt”,因为该路径不存在。 所在位置 行:12 字符: 1 + ls '\\website14\c\WFTest\1.txt' + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (\\website14\c\WFTest\1.txt:String) [Get-ChildItem], ItemNotFoundException + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id SI ProcessName PSComputerName ------- ------ ----- ----- ----- ------ -- -- ----------- -------------- 255 50 20480 19768 515 0.25 9280 0 WMSvc website14 LastWriteTime : 2017/7/6 12:55:47 Length : 5 Name : 1.txt
