Another way doing it is
Set the error action preference 'Stop', so all the terminating and non-terminating errors will be logged, and moreover all the non-terminating erros will become terminating so you can trap for the errors:
$ErrorActionPreferenceOld = $ErrorActionPreference
$ErrorActionPreference = 'Stop'
Connect-ViServer -Server $srv -User $usr -Password $pass
trap {
#handle the error $_
}
#restore the error action preference
$ErrorActionPreference = $ErrorActionPreferenceOld
The difference between the two approaches is that this terminates the command immediately after the error occurs:
1. Connect-VIServer -Server (<invalid_server>, <server>) -User <user> -Password
<pwd> -ErrorAction silentlycontinue -ErrorVariable ErrorString
- will try to connect to both servers (will not terminate) and will store the error in the ErrorString variable
2. $ErrorActionPreference = 'Stop'
Connect-VIServer -Server (<invalid_server>, <server>) -User <user> -Password
<pwd>
- will stop on the first server and will report the error
