I have multi vCenters I need to run yum update to all Linux servers, on all sites, so I have written an update function
I need to run that inside a job script, and return the result, the job is stuck at running
function Update-VM {
[CmdletBinding()]
Param(
[Parameter(Mandatory = $true, ValueFromPipeline = $true)]
$vm
)
