我有这个powershell脚本，我打电话来备份我们客户的虚拟机：

我怎么会这样做，所以我的脚本将停止打破？
谢谢！
长颈
我改变了这个代码：
Stop-VM -Name $VMNames while ((get-vm -name $vmnames).state -ne 'Running') { $a = Get-Date Write-Output "Waiting 5 seconds for $VMName to stop: $a" $state = (get-vm -name $vmnames).state Write-Output "State: $state" start-sleep -s 5 }
我得到这个：
PS H:\> H:\VeeamBackupZimbra.ps1 Waiting 5 seconds for ZIMBRA to stop: 07/21/2016 14:39:03 State: Off Waiting 5 seconds for ZIMBRA to stop: 07/21/2016 14:39:08 State: Off Waiting 5 seconds for ZIMBRA to stop: 07/21/2016 14:39:13 State: Off Waiting 5 seconds for ZIMBRA to stop: 07/21/2016 14:39:18 State: Off Waiting 5 seconds for ZIMBRA to stop: 07/21/2016 14:39:23 State: Off
无尽的循环。
有什么build议么？
这将等待虚拟机运行：
while ((get-vm -name $vmnames).state -ne 'Running') { start-sleep -s 5 }
这将等到VMclosures：
while ((get-vm -name $vmnames).state -ne 'Off') { start-sleep -s 5 }
