in 3 Steps Dealing with the inevitable events in life – reporting problems with PowerCLI → Tweet Error handling with PowerCLI 4.1 Posted on July 23, 2010 by Dimitar Hristov Leave a reply Complex scripts need to powercli exception handling handle errors and resolve common error scenarios without user interaction. A step in that powercli check if vm exists direction is exposing the entire specter of vCenter server error hierarchy along with PowerCLI specific exceptions (for example when validating input parameters).
Get-vm Erroraction
This improvement makes possible to write scripts which handle expected errors and deal with them as it’s shown below: In addition to this feature the full exception chain is available in the error records as inner

exception. So if the error is PowerCLI specific exception, the inner exception can be used to get the underlying vCenter Server error. Thanks to that you can easily tune your script to check the returned by the server NoDiskSpace MethodFault and deal with it specifically.

For example, let’s check if a specific user exists on our ESX host (you need to connect
Powershell Error Handling
directly to the ESX host for this example to work). We do this by powershell catch exception running: Get-VMHostAccount -Id UserName If the user exists, you get the user object back. But if it doesn’t exist, the command gives you an error and your script continues with its operation. This is because the default $ErrorActionPreference is set to Continue. Let’s say we want to check if a user Test exists and if not we’ll create one. http://blogs.vmware.com/PowerCLI/2010/07/error-handling-with-powercli-41.html We could do a Get-VMHostAccount –User:$true and loop the result to check if our User Test exists. But this isn’t very efficient as we will fetch tons of users which we basically don’t need. So it’s better to look for the user Test in the first place without fetching all those unnecessary users. This is done with the Get-VMHostAccount –Id “Test” cmdlet. This way of looking for a user’s existence is about 15 times faster https://boerlowie.wordpress.com/2010/10/13/how-to-use-try-catch-in-powercli-the-easy-way/ than looping through all existing users! If we build a Try – Catch loop around it, it’s easy to create the user if the Get-VMHostAccount produces an error: Try { Get-VMHostAccount -Id "Test" Write-Host "Found" } Catch { Write-Host "Not Found, let's create one" New-VMHostAccount -Id "Test" -Password "Test" -WhatIf:$true } Let’s run it on our ESX server which has no Test user: The Get-VMHostAccount produces an error (which is normal), but then the script writes the output Found!!! This seems illogical at first sight (you would expect the Error be catched and have the user created), but actually makes sense. A Try – Catch only works on Terminating errors. Note that the default $ErrorActionPreference for PowerShell is set to Continue, which means that by default, errors are non-terminating (ensuring your scripts continues to run at all times). So we’ll have to make sure the Get-VMHostAccount produces a Terminating error. This is done by adding the –ErrorAction Stop parameter to the cmdlet. Try { Get-VMHostAccount -Id "Test" -ErrorAction Stop Write-Host "Found" } Catch { Write-Host "Not Found, let's create one" New-VMHostAccount -Id "Test" -Password "Test" -WhatIf:$true } Let’s run this piece of code again: Bingo! Exactly what we need! Fast and clean code! You can use this approach for all kinds of things to check for: - Check if a file exists

I'm using this cmdlet: New-VM error handling -Name MyName -VM $sourceVM -Datastore $myDataStore -VMHost (Get-VMHost) But it returns following exception: New-VM The operation for the entity "xxx" failed with the following message: "The operation is not supported on the object." The source VM is powered off. Version of vSphere is 5.5. I tried to google this error but without any success. Now, I have no idea where the problem is. vmware vsphere powercli share|improve this question edited Jun 14 at 10:18 asked Jun 14 at powercli new-vm error 9:54 user2250152 744617 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Get-vmhost by itself will return all hosts and not specify one host to use, which is what this command expects. If you know a host you wish to build on you could use the below script: New-VM -Name MyName -VM $sourceVM -Datastore $myDataStore -VMHost $(Get-VMHost "specify host name") Otherwise you could build an array and select a vmhost from that array by using the below # This command builds an array of all you host names into the variable $vmh $vmh = get-vmhost # This command selects random host from this array assigning it to the $vmhost variable $vmhost = Get-random -inputobject $vmh # Now build your VM command with the randomly selected host New-VM -Name MyName -VM $sourceVM -Datastore $myDataStore -VMHost $vmhost Make sure you are defining a datastore in a similar fashion as well for your $mydatastore variable Just making a variable built off get-datastore will not work you have to narrow it down to a single store for the operation New-VM to work $mds = get-datastore $mydatastore = Get-random -InputObject $mds Also make sure your $sourceVM is being defined correctly as well. if more than one object is in this variable it will not work. Make sure $sourceVM equals a single VM name. As you can see below, when I run the comm
