Run Batch in Guest Remotely via PowerCLI

[nicholas1982]

Hi All,

I'm sure I've come across a script that can execute a batch file within Windows guests remotely using PowerCLI, but for the life of me I can't find it.

I have 4 Windows VMs, which have the same login credentials, they have a test.bat file in the same location, I need a way of executing the batch remotely via PowerCLI simultaneously, is this possible?

You can do that with the Invoke-VMScript cmdlet

Thanks Luc,

It seems to be almost working but I get the following output (see image)

I should also point out I connected PowerCLI directly to the host not vCenter, the batch file I'm trying to run is an SQLIO.exe with the following:

@ECHO OFF

sqlio -kR -t8 -s120 -frandom -o32 -b4 -BH -LS -Fparam.txt

[LucD]

It looks as if the sqlio command is not found. Could be that the directory is not in the Path variable in that OS.

Try with the full path to the sqlio executable.

Hi Luc,

Rather than running the batch this seems to work.

Invoke-VMScript -VM VM1 -ScriptText "C:\SQLIO\SQLIO.EXE -s120 -kR -frandom -b4 -t4 -o32 -LS -BH e:\Testfile.dat" -GuestUser administrator -GuestPassword password

Can you help me with having this executed simultaneously on multiple guest VMs ?

Hi Luc,

I think I acutually almost have it, I'm just having trouble specifying the GuestCredential

$guestvms = "flash1,flash2,flash3"

$guestCredential = ?????

$myscript = "C:\SQLIO\SQLIO.EXE -s120 -kR -frandom -b4 -t4 -o32 -LS -BH e:\Testfile.dat"

Invoke-VMScript -VM $guestvms -ScriptText $myscript -GuestCredential $guestCredential

[LucD]

If you want to be prompted for the credentials, you can use the Get-Credential cmdlet,

Otherwise you can do something like this

$username = "MyUserName"

$password = ConvertTo-SecureString "MyPassword" -AsPlainText -Force

$cred = New-Object -TypeName System.Management.Automation.PSCredential -Argumentlist $username,$password

Hi Luc,

Any chance you might be able to see where I'm going wrong here, I need to overwrite a txt file within a guest with this value "e:\testfile.dat 8 0x0 11000"

$guestvms = "flash3"

$myscript = "e:\testfile.dat 8 0x0 11000 | Out-File C:\SQLIO\param.txt"

Invoke-VMScript -VM $guestvms -ScriptText $myscript -GuestUser administrator -GuestPassword Password

[LucD]

The default ScriptType for Windows guest OS is PowerShell.

So you probably have an error saying that there is an "unexpected token" or something along that line.

You will have to make sure that PowerShell sees that first part as a [string], so place it between quotes.

Something like this

$guestvms = "flash3"
$myscript = '"e:\testfile.dat 8 0x0 11000" | Out-File C:\SQLIO\param.txt'
Invoke-VMScript -VM $guestvms -ScriptText $myscript -GuestUser administrator -GuestPassword Password

Those are single quotes on the outside double quotes around the [string].
