parallel Execution using Powershell

[Developer_PK]

I am working on a activity which needs to get uptime from several servers. I am using Invoke-vmscript to do this activity. I want to use Parallel processing to reduce time.

Without a new ps session and using jobs. Is there any other way to do parallel execution.

I have tried Foreach-object -parallel, this didnot work because my powershell version is not 7.

Any suggestion Helps!

Thanks in advance

If your PS is not PSv7 and you don't want to use Start-Job, then the other option is to look at runspaces.
But be aware that PowerCLI is not threadsafe.

HI LucD,

Can you help me, by using jobs.
I had to run a script which is large on multiple servers. Can you help me with using Jobs.

Thanks in advance

There is a sample in Solved: Re: Pass vCenter connection to a Job - VMware Technology Network VMTN

Hi LucD,
I got this warning in the job output. Can you help me with this.

That is a normal warning, just execute the command on the last line with either $true or $false.
You are setting up a new environment, hence this warning.

Thanks much for reply.
I want to send a Another variable to Argument list. So that it should Take the variable data in to code block.
Like I want to pass multiple variables to arugementlist. 
Is this possible?
I want to run a code block for multiple servers to fetch data.
$vmnames |%{
$scriptblock = { #code}
Start-Job $ScriptBlock -ArgumentList $_
}
This way i am using the code block.

If you read that thread I pointed to earlier, you'll notice it also discusses passing an array.
Also, in that thread I point to an example on my blog where we pass 3 arguments to the job.

you basically have the answer, just install the PowerShell 7 and get the job done,

and you don't have to worried about the warning,  just run the below command and be done with it.
Set-PowerCLIConfiguration -Scope User -ParticipateInCEIP:$false
