How to open the VMware Remote Console (application) from the PowerCLI

I'm not exactly sure how you set those in the first place but you can remove the variables (rather than null them) using the following.

1) First check what you have with in a fresh PowerCLI session with Get-Variable (you should see something like this but likely a value for a server)

Name                           Value
----                           -----
global:DefaultVIServer         
global:DefaultVIServers        {}

2) Remove each using Remove-Variable DefaultVIServer and Remove-Variable DefaultVIServers 3) Try connecting to the correct vCenter with Connect-VIServer yourvcenter.domain.com*

If you keep having variables reset, it's possible you've customized something in the startup file (C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1) so you might need to replace/remove the entries there (never tried that, just taking a guess)

PS. Sorry about formatting messs, still getting used to the format

To find all vmhosts with alarm status = "red", I expanded on this.

#
# Find all hosts with triggered alarms in "Red" state
#
$esx_all = Get-VMHost | Get-View
$Report=@()
foreach ($esx in $esx_all){
    foreach($triggered in $esx.TriggeredAlarmState){
        If ($triggered.OverallStatus -like "red" ){
            $lineitem={} | Select Name, AlarmInfo
            $alarmDef = Get-View -Id $triggered.Alarm
            $lineitem.Name = $esx.Name
            $lineitem.AlarmInfo = $alarmDef.Info.Name
            $Report+=$lineitem
        } 
    }
}
$Report |Sort Name | export-csv "c:\temp\ESX-Host-Red-Alarms.csv" -notypeinformation -useculture
Invoke-item "c:\temp\ESX-Host-Red-Alarms.csv"
