Powershell New-F5Session and close session issues.

Hi,   We have some automation around some F5 functionality.  We have moved from 1 F5 to 2 F5s,  one for external apps and one for internal apps.   In our powershell automation we now have to create t...

Hi JRahm,   Thanks.  I did also post over there.  Headed over there to see if there was any response.

I posted in this area  https://github.com/joel74/POSH-LTM-Rest/issues  not sure if that was the right one but it seemed to have the most activity.

thanks

Lance

Did you try the passthru switch Joel mentioned in the issue I shared? Seems to be the same scenario you mentioned, but posh is not my jam so I'm just throwing ideas out.

    Yeah,  I am able to get it to work for 1 session but I am not sure how to do 2 sessions since we have 2 F5s that we have to change iRules on.     It seems like the  New-F5Session is part of the scripts attributes and so the calls to Add-iRuleToVirtualServer assumes the "current F5 session" that is open so passthru might be the default.   Joel may know of an alternative so I will have to wait and see.

    I can always create another script that handles iRules for the other F5 but it involves a little more work and 2 separate scripts and commands to be created and executed.

      Looking through some comments on the codeshare, i found this:

       

      $F5Session = New-F5session -LTMName $host_address -LTMCredentials $mycreds -PassThrough; 
Get-Pool -F5Session $F5Session | Select-Object -ExpandProperty fullPath;

       

      So maybe if you had that in a loop and just passed in $host_address from the iterable it would update? No worries if you've tried this, still slinging mud against the wall in the event something sticks... 🙂

        Hi Jason,  

        I have left a post over in this area for Joel but have not heard back  https://github.com/joel74/POSH-LTM-Rest/issues/219

        I have tried the code below and I still get this error thinking its coming from the Get-VirtualServer calls

        You must either create an F5 Session with script scope (by calling New-F5Session with -passthrough parameter) or pass an F5 session to this function.
        $session_inside = New-F5Session -LTMName $ltmip_inside -LTMCredentials $mycreds
$vipObject_inside = Get-VirtualServer -F5Session $session_inside -Name $vipName
               
$session_external = New-F5Session -LTMName $ltmip -LTMCredentials $mycreds 
$vipObject_external = Get-VirtualServer -F5Session $session_external -Name $vipName    
                
if ($vipName.ToLower() -contains "internal") {
   $vipObject = $vipObject_inside
} else {
   $vipObject = $vipObject_external
}
                
foreach ($viprule in $vipObject.rules) {
   switch ($action.tolower()) {
     "add" {
         switch ($type.tolower()) {
            "all" {
                if ($vipName.ToLower() -contains "internal") { 
                  $add = Add-iRuleToVirtualServer -F5Session $session_inside  -InputObject $vipObject -iRuleName $all_MaintRule
                } else {
                  $add = Add-iRuleToVirtualServer -F5Session $session_external -InputObject $vipObject -iRuleName $all_MaintRule
                }
                $status = "Updated"
             }
             "external" {
                if ($vipName.ToLower() -contains "internal") {
                  $add = Add-iRuleToVirtualServer -F5Session $session_inside  -InputObject $vipObject -iRuleName $external_MaintRule
                } else {
                  $add = Add-iRuleToVirtualServer -F5Session $session_external -InputObject $vipObject -iRuleName $external_MaintRule
              }
              $status = "Updated"
           }
             default {
               $status = "Error - rule type not specified"
             }
          } 

         }
      "remove" {
          if ($vipName.ToLower() -contains "internal") {
             $remove = Remove-iRuleFromVirtualServer -F5Session $session_inside -InputObject $vipObject -iRuleName $all_MaintRule
             $remove = Remove-iRuleFromVirtualServer -F5Session $session_inside -InputObject $vipObject -iRuleName $external_MaintRule
          } else {
             $remove = Remove-iRuleFromVirtualServer -F5Session $session_external -InputObject $vipObject -iRuleName $all_MaintRule
             $remove = Remove-iRuleFromVirtualServer -F5Session $session_external -InputObject $vipObject -iRuleName $external_MaintRule
          }

          $status = "Updated"
         }
          default {
            $status = "Error - action type not specfied"
          }
       }
    }
