Cisco UCS Powertool scripts using powershell

UCS scripts are handy, when you find yourself in situations where a project requires you to add 500+ VLANS to UCSM. When the task is time consuming you should find a way to automate it. If your scripting skills isn’t up to scratch, you need to weigh up the time to script vs manually performing the task. Hopefully, the script examples at bottom of this page may have turnkey script that could be a use to you.

Cisco developed UCS Powertool to automate UCS tasks using Powershell cmdlets. You can Download Powertool software and install it on the computer / server you have access to UCSM from. Once the executable has been installed, follow the simple steps below.

UCS ConvertTo-UcsCmdlet procedure:

  1. Load Manager PowerTool. powertool program icon
  2. Connect to a UCSM cluster IP (or emulator) by typing “Connect-Ucs <UCSM-IP address> or <hostname>” command. Enter the UCSM login details when prompted.
  3. After successful login, execute the cmdlet “Start-UcsGuiSession -LogAllXml” in Powertool to kick off the UCSM GUI.
  4. Once GUI has launched, type “ConvertTo-UcsCmdlet” in the PowerTool window prompt.
  5. To get the commands for an action within UCSM, perform the steps as you would want within UCS GUI. e.g. Create a VLAN or Add a VLAN to vNIC template. If you are familiar with Excel Micros then this step would be something similar.
  6. After few seconds, UCS Powertool will spit out the cmdlets for the action you just performed in UCSM GUI.

If you have a long list of VLANS to add then best to stick it in an Excel spreadsheet and do what I did below and then save full commands as filename.ps1:

In some cases, where you already have bunch of VLANs within UCS and you wish to add some of it to VLAN Groups, then it’s easier to export the names to a CSV from the screen below and do what I did with Excel above to concatenate.

Some other common cmdlets in UCS Powertool are:

  • Get-Ucsblade
  • Get-UcsServiceProfile
  • Connect-UcsServiceProfile -ServiceProfile ServiceProfileName -Blade ServerID
  • Full reference list of Reference guide for Powertool can be found here for version 1.x.

You can check the operational status of the cluster and Fabric Interconnects using “Get-ucsfimodule ¦ select descr,operstate“.
