PowerCLI's RunAsync Parameter Rocks!
I've recently been playing around with the -RunAsync parameter in some of my PowerCLI scripts, and I'm super impressed! I'm also super late to the party; I mean, LucD was writing about it back in 2010, but still! So, what's it do? It speeds up tasks that don't need to be run sequentially, that's what it does. For example, if I have a list of VMs that all need to move into a new folder, I could do it like this: $folder = get - folder "New Folder" $vmNames = get - content MyList.txt foreach ($vmname in $vmNames){ get - vm $vmname | move - vm - destination $folder } And that would move one VM, then the next, then the next, etc. Depending on the number of VMs, it could take a real long time. This process could take a while because, the way this script is written, the system will wait for each "move" to complete before initiating the next. That's where -RunAsync comes in. $folder = get - folder "New Folder" ...
