Instructions for Custom Workflow Use:
- Download the attached .ZIP file to your computer. Note: Remember the location of the saved file on your computer.
- Unzip the file on your computer. The unzipped file ends up with an extension .WFDX file.
- Log in to UCS Director as a user that has the system admin privileges.
- Choose Policies > Orchestration, and then click the Custom Workflow Tasks tab.
- Click Import Tasks.
- In the Import Tasks dialog box, click Browse and choose the downloaded file for upload. Click Upload. A successful file upload message appears.
- Click OK.
- Click Next.
- The Save Tasks window displays the task exported time, task exported username, and comments provided when the task is exported. The imported task details appear in a table format.
- Check the Overwrite if the task exists with same name check box to overwrite the existing task with the imported task.
- If this check box is unchecked, a new task will be added with a number (n) to make the name unique.
- Click Import.
- The custom workflow task is imported and is immediately available for use in the workflow.
- Create a basic workflow. For more information, see the Creating a Workflow section in the Cisco UCS Director Orchestration Guide, Release 4.1.
- Add the imported workflow task to the workflow. For more information see the Adding Tasks to a Workflow section in the Cisco UCS Director Orchestration Guide, Release 4.1
- Click Submit.
- Click the workflow, the workflow designer opens.
- In the workflow designer window, click the Execute Now button.
- A service request is created for the workflow.
Instructions for Regular Workflow Use:
- Download the attached .ZIP file below to your computer. *Remember the location of the saved file on your computer.
- Unzip the file on your computer. Should end up with a .WFD file.
- Log in to UCS Director as a user that has "system-admin" privileges.
- Navigate to "Policies-->Orchestration" and click on "Import".
- Click "Browse" and navigate to the location on your computer where the .WFD file resides. Choose the .WFD file and click "Open".
- Click "Upload" and then "OK" once the file upload is completed. Then click "Next".
- Click the "Select" button next to "Import Workflows". Click the "Check All" button to check all checkboxes and then the "Select" button.
- Click "Submit".
- A new folder should appear in "Policies-->Orchestration" that contains the imported workflow. You will now need to update the included tasks with information about the specific environment.
