PowerCli Assistance

I am looking for a way to script the turn on of VMs in a specific order using wild cards. Some of the requirements are as follows:

1. Systems need to be powered on in groups.
2. Systems need to come up before other systems come up (specific order).

What I am looking at is a few lines of code where a set of servers is defined using wild cards. In the below example I would like all DCs to come up first if they are in a powered off state, wait for tools to load (system is actually up) then move on to the next step and do the same for file servers with a naming format of *File0*, then servers in the format *FS0*, etc... Each line of code should not execute until the Wait-Tools comes back good. Main reason for this is certain systems need to be up before others or some apps don't work right.

Start-VM *DC0* | Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All Domain Controllers come up

Start-VM *File0* | Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All servers with File0 in the name come up

Start-VM *FS0* | Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All Servers with FS0 in the name come up

Start-VM *WEB* | Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All Servers with WEB in the name come up

Start-VM *DB1P* |  Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All Servers with DB1P in the name come up

Start-VM *DB2P* |  Where-Object {$_.powerstate -eq ‘PoweredOff’} | Wait-Tools

• All Servers with DB2P in the name come up

When I use the WhatIf parameters it tells me all of the servers it would power on but does not go beyond the Start-VM Command so I cannot tell if the Where clause or Wait-Tools command do anything. I don't have a sandbox to play in yet so I figured I would ask the experts and see if I am on the right track first.

Thx!

See if this helps:

$doathing = $false   #   <Set this to $true to do a thing! set to $false to see what it would do!

$vmGroups = @{'Group01'='dc0'
              'Group02'='file0'
              'Group03'='fs0'
              'Group04'='web'}

$i = 1
do
{
  #decipher what things we are doing things to!
  $groupNumber = "{0:D2}" -f [int]$i
  $groupName = "Group" + $groupNumber
  $groupVms = Get-VM | where {$_.Name -match $vmGroups.$groupName -and $_.powerstate -eq 'PoweredOff'}

  #start the Vms!
  foreach ($Vm in $groupVms)
  {
    Write-Host "Starting $($Vm.Name)"
    if ($doathing -eq $true){$Vm | Start-VM}else{Write-Host "Didn't start VM $($Vm.Name) because doathing is false!"}
  }

  #wait for tools on each Vm!
  foreach ($Vm in $groupVms)
  {
    Write-Host "Waiting for tools on $($Vm.Name)"
    if ($doathing -eq $true){$Vm | Wait-Tools}else{Write-Host "Didn't wait for tools on VM $($Vm.Name) because doathing is false!"}
  }
  $i++
}
while($i -le $vmGroups.Count)

You would first need to "get" the VM ebfore chekcing the powerstate, and then power on the ones that aren't.

Something like this

Get-VM *DC0* | Where-Object {$_.powerstate -eq ‘PoweredOff’} | Start-VM | Wait-Tools

both solutions look good but this one was simplest.

I have another question more related to running this script in SRM if anyone can chime in on that it would be great:

I saw that thread, but I'm afraid I don't have an answer to those questions right now.

Will have to spend some more lab time on SRM :smileycry:
