Utility for running failover scripts in a guest

Hi Shannon. Looks like attachments didn’t make their way through the transition to myZerto.

Any chance you could re-attach to this post?

Thanks!

Looks like the utility mentioned here is not attached.  I was able to use the below script to run a command inside of the GuestOS, run it in VMware PowerCLI.  Now that I have it working it shouldn’t be too hard to make it work with Zerto’s pre post failover script on the VPG.

The script uses “Invoke-VMscript”, the way it works is that ESXi host tells VMware tools to run a command inside of the GuestOS.

The below script changes the IP and DNS settings inside of the guestOS that you specify.  The plan is to re-ip a Windows 2000 box after a failover.  Change “Connect-VIServer vcenter1.mylab.local” so that it points to your vCenter.  When executed it will prompt you for the VM name, ESXi host password, GuestOS username/password and then it will run the 3 netsh commands listed below.

To get it to work in Windows 2003, etc, you will need to change the path to netsh.exe.

Win2000IPDNSChange.ps1

Function Set-WinVMIP ($VM, $HC, $GC, $IP, $SNM, $GW, $DNS1, $DNS2){
$netsh = “c:\WINNT\system32\netsh.exe interface ip set address “”Local Area Connection”” static $IP $SNM $GW 1″
$netshdns1 = “c:\WINNT\system32\netsh.exe interface ip set dns “”Local Area Connection”” static $DNS1″
$netshdns2 = “c:\WINNT\system32\netsh.exe interface ip add dns “”Local Area Connection”” $DNS2 index=2″
Write-Host “Setting IP address for $VM…”
Invoke-VMScript -VM $VM -HostCredential $HC -GuestCredential $GC -ScriptType bat -ScriptText $netsh
Write-Host “Setting IP address completed for $VM.”
Write-Host “Setting DNS1 for $VM…”
Invoke-VMScript -VM $VM -HostCredential $HC -GuestCredential $GC -ScriptType bat -ScriptText $netshdns1
Write-Host “Setting DNS1 completed for $VM.”
Write-Host “Setting DNS2 for $VM…”
Invoke-VMScript -VM $VM -HostCredential $HC -GuestCredential $GC -ScriptType bat -ScriptText $netshdns2
Write-Host “Setting DNS2 for $VM completed.”
}

Connect-VIServer vcenter1.mylab.local

$VM = Get-VM ( Read-Host “Enter VM name” )
$ESXHost = $VM | Get-VMHost
$HostCred = $Host.UI.PromptForCredential(“Please enter credentials”, “Enter ESX host credentials for $ESXHost”, “root”, “”)
$GuestCred = $Host.UI.PromptForCredential(“Please enter credentials”, “Enter Guest credentials for $VM”, “”, “”)

$IP = “192.168.0.81”
$SNM = “255.255.255.0”
$GW = “192.168.0.1”
$DNS1 = “192.168.0.100”
$DNS2 = “192.168.0.101”

Set-WinVMIP $VM $HostCred $GuestCred $IP $SNM $GW $DNS1 $DNS2
