Formating List Problems in Powershell - powershell

Question

I want to execute a few lines of code on every Server (160+).
For this I decided to get my Serverlist via Powercli and pass this list to Enter-PSSession.
...
Connect-VIServer -Server $VIServer -Credential $creds
$servers = Get-VM |select Name |where Name -Like "SV*"
...
foreach($server in $servers)
{
try{
Enter-PSSession -ComputerName $server -Credential $cred -ErrorAction Stop
Get-NetIPAddress |where AddressFamily -EQ 2 |where InterfaceAlias -Like "Ethernet" |select IPAddress
Exit-PSSession
}catch{
Write-Host "Error on $server"
}
}
the problem seems to be, that it takes an array as the ouput error is following
Error on #{Name=<$server>}
But I dont know how to handle this correctly

Answer 1

Use New-Pssession or Invoke-command for remoting. Enter-Pssession is interactive and the way you are doing it, the get-netipaddress is running on your local machine and not on your remote machine.
Use $servers.Name instead of $servers in your foreach loop.
foreach($server in $servers.Name) #This .name should fix your problem
{
try{
New-PSSession -ComputerName $server -Credential $cred -ErrorAction Stop -Name MySession
Invoke-Command -Session $MySession -ScriptBlock {Get-NetIPAddress |where AddressFamily -EQ 2 |where InterfaceAlias -Like "Ethernet" |select IPAddress}
Remove-PSSession
}catch{
Write-Host "Error on $server"
}
}
