Check vCenter Connectivity

SCharchouf — Thu, 19 Nov 2020 11:56:03 GMT

I'm trying to connect to some vCenters via PowerCLi and I would like to be sure that there's no session already logged.

I'm using this script but it show me always the last vcenter connected twice

$vCenterList = Get-Content ".\vCenterList.txt"

###Check if we are connected to vCenter Server(s)
foreach ($vCenter in $vCenterList){
if($global:DefaultVIServers.Count -gt 0){
# Return current connection
$global:DefaultVIServers[0]
}
else
{
# Finally, connect to the VMware vCenter
Connect-VIServer -Server $vCenterList
}
}

would you please assist me to correct the script in order to show to which vcenter(s) I'm already connected if not connected then it proceed with connectivity

What is in $global:DefaultVIServers before you start your script?
Perhaps do a Disconnect-VIServer -Server * -Confirm:$false at the start of the script.

I have nothing in $global:DefaultVIServers

Disconnect-VIServer -Server * -Confirm:$false at the start of the script.

I thought about doing it but it would be smarter to do it via the loop unless it is not possible

Then I would do something like this

$vCenterList = Get-Content ".\vCenterList.txt" foreach ($vCenter in $vCenterList){ if($global:DefaultVIServers.Name -contains $vCenter){ # Return existing connection $global:DefaultVIServers | where{$_.Name -eq $vCenter} } else { # Finally, connect to the VMware vCenter Connect-VIServer -Server $vCenterList } }
