Hi, Im trying to get the OS installed on each of my VM's using WMI but some of the machines I dont have Admin access to, thats fine but I dont want it to stop I want it to keep going through the list, any ideas why this doesnt keep going ?

 

$ErrorActionPreference = "SilentlyContinue"
Connect-VIServer myviserver
get-vm | Foreach-object {Get-WmiObject -class Win32_OperatingSystem -computername $_}|Select-Object CSName, Caption

I ask here as its a WMI query and not a VI Toolkit issue.

 

Thanks

I can't test against VMWare but you can try to set the -errorAction param on the Get-WmiObject cmdlet:

Get-WmiObject -class Win32_OperatingSystem -errorAction SilentlyContinue

I see that you pass $_ as computer name. Try you pass the full member name (i dont know what get-vm output as the machine name, so I guess its name), try to pass $_.name.

If still don't work, can you try without get-vm and with a bogus names, doe's this output any error:


Get-WmiObject -class Win32_foo -computer dontExist -errorAction SilentlyContinue

I dont think the name is the issue as it works for about the first 5 machines which I have access to until it gets to one of the machines I dont get access to :(

 

Thanks for the idea though !

Silly me, access denied is a terminating error, add a trap statment:

get-vm | Foreach-object {trap {continue}; Get-WmiObject -class Win32_OperatingSystem -computername $_}|Select-Object CSName, Caption

You are truly amazing, that worked a treat.

 

Thanks very much !

Will this also work for WMI hangs?

If it reports an error :-) or until the timeout period has finished.

Shay I have this script that hangs when I try to get owner..how do I set the trap and time-out, thanks for your help

Foreach ($strComputer in Get-Content C:\Powershell\Host\btsp.txt)
{
$query = "select * from win32_pingstatus where address = '$strcomputer'"
$result = Get-WmiObject -query $query
if ($result.protocoladdress)
{
#$Proc = gwmi -query "select * from win32_process where name='Proc.exe'" -comp $strComputer
# If ($Proc.processname -eq "Proc.exe")
foreach ($Proc in (gwmi -query "select * from win32_process where name='Proc.exe'" -comp $strComputer))
{
Trap
{
Throw "Could not get owner"
Return $_ | continue
}
$c.Cells.Item($intRow,1) = $strComputer
$c.Cells.Item($intRow,2) = $Proc.name
$c.Cells.Item($intRow,3) = $Proc.ProcessID
$c.Cells.Item($intRow,5) = $Proc.ExecutablePath
$c.Cells.Item($intRow,6) = $Proc.ConvertToDateTime($Proc.CreationDate)

$Proc1 = ($Proc).getowner()
$c.Cells.Item($intRow,4) = ($Proc1).user
$intRow = $intRow + 1
}

Else
{
$c.Cells.Item($intRow,1) = $strComputer
$c.Cells.Item($intRow,2) = "No Proc Process"
$intRow = $intRow + 1
}
}
Else
{
$c.Cells.Item($intRow,1) = $strComputer
$c.Cells.Item($intRow,2) = "Not Responding"
$intRow = $intRow + 1
}

What do you get for this:



Foreach ($strComputer in Get-Content C:\Powershell\Host\btsp.txt){
$query = "select * from win32_pingstatus where address = '$strcomputer'"
$result = Get-WmiObject -query $query

if ($result.protocoladdress){
trap { continue }
gwmi -query "select * from win32_process where name='Proc.exe'" -comp $strComputer | ft

}
}

Shay - My script hangs when I am trying to get the owner of a process..intermittently..I ran it on 200 + servers
I was wondering how do I set up a trap so the script get the error and continue on?

$Proc = gwmi -query "select * from win32_process where name='Proc.exe'" -comp $strComputer
$proc2=($Proc).getowner()
write-host $proc2.user

Thanks for ur help

First, I would ping each machine beofre trying to get the owner. Second, your command can get multiple process objects so it's safer to use foreach:

$procName = "proc.exe"
$strComputer = "serverName"

$ping = gwmi win32_pingstatus -filter "address='$strComputer'"

if($ping.statusCode -eq 0){
# uncomment the next line if you get terminating errors
#trap {continue}
$procs= gwmi win32_process -filter "name='$procName'" -computer $strComputer
$procs | foreach { $_.getowner() } | select __server,user
}
