Provisioning OS Images through Orchestration Workflow Tasks

This chapter contains the following sections:

Orchestration Workflow Tasks for PXE/vMedia Boot

The orchestration workflow tasks for PXE/vMedia boot enable you to create workflows within Cisco UCS Director that use the functionality of Cisco UCS Director Bare Metal Agent.

When you include any of the PXE/vMedia boot tasks in an orchestration workflow, the task prepares the Bare Metal Agent environment to receive a PXE install request for a physical or virtual machine.

The values for each input required within the task can be supplied in one of the following ways:

  • As user inputs by the user who executes the workflow

  • Through outputs from a previous task in the workflow

  • Through admin inputs that are assigned by the Cisco UCS Director user who creates the workflow

The following orchestration workflow tasks are available:

  • Setup PXE/vMedia Boot task

  • Setup PXE/vMedia Boot with BMA Selection task

  • Setup Windows PXE/vMedia Boot task

  • Monitor PXE/vMedia Boot task

  • Remove PXE/vMedia Boot Setup task


Note

To set up a PXE/vMedia boot for a Windows Server operating system, you must use the PXE/vMedia boot setup task that is defined specifically for Windows. To set up a PXE/vMedia boot for all other supported operating systems, use the Setup PXE/vMedia Boot task or the Setup PXE/vMedia Boot with BMA Selection task.

You can access these workflow tasks in the Network Services area of the Cisco UCS Director Workflow Designer Task Library.

Most inputs and outputs are the same for the Setup PXE/vMedia Boot task, the Setup PXE/vMedia Boot with BMA Selection task, and the Setup Windows PXE/vMedia Boot task, with the following notable exceptions:

  • The Setup PXE/vMedia Boot with BMA Selection task has an input field for selecting the target Bare Metal Agent.

  • The Setup PXE/vMedia Boot task does not have an option to select the target Bare Metal Agent. This legacy workflow task uses the default Bare Metal Agent as the target Bare Metal Agent.

  • The Setup Windows PXE/vMedia boot task has an input field for selecting the target Bare Metal Agent.


Tip

For the legacy Setup PXE/vMedia Boot task, the default Bare Metal Agent is the first Bare Metal Agent added. However, you can change the default Bare Metal Agent. See Changing the Default Bare Metal Agent Account.

Prerequisites for Workflows with PXE/vMedia Boot Tasks

If you plan to create orchestration workflows that include one or more of the PXE/vMedia boot tasks, your Cisco UCS Director and Cisco UCS Director Bare Metal Agent environment must meet the following prerequisites:

  • Cisco UCS Director has been installed and the network interface configured as described in the appropriate Cisco UCS Director installation guide.

  • Cisco UCS Director is reachable through a web browser and you can log in.

  • Cisco UCS Director Bare Metal Agent has been installed as described in Installing Cisco UCS Director Bare Metal Agent.

  • The required network/VLAN has been configured as the native, or default, VLAN on the server. For example, for a Cisco UCS server, edit the vNIC template associated with the server and choose the PXE network/VLAN as the native VLAN. You can perform this configuration through an orchestration workflow.

  • Each Bare Metal Agent account that you want to use in a workflow has been set up, is active, has a tested connection, and has services that have been enabled and started.

Execution of the Setup PXE/vMedia Boot Tasks

The following Setup PXE/vMedia Boot tasks are available for use in workflows:

  • Setup PXE/vMedia Boot task

  • Setup PXE/vMedia Boot with BMA Selection task

  • Setup Windows PXE/vMedia Boot task

Each time that one of these tasks is executed within a workflow, Cisco UCS Director uses the following values for the inputs to complete a set of configuration files for that particular PXE request:

  • Dynamic values received from previous tasks in the workflow or from the user at run-time.

  • Static values that you enter when you create the workflow.

  • Template configuration files—the ks.cfg Kickstart files—that were created when the chosen operating system was added to Bare Metal Agent. For more information about these files, see Sample Operating System Configuration Template Files.

When the workflow is executed, Bare Metal Agent and Cisco UCS Director use the values gathered through the task and perform the following steps to prepare for a PXE installation request on the specified server:

Step Action Notes

1

Creates a new directory in the Cisco UCS Director Bare Metal Agent VM that corresponds to the PXE ID request in the /opt/cnsaroot/web/ks-repository/ directory.

You can view these PXE requests and PXE IDs on the PXE Boot Requests tab for a pod in Cisco UCS Director.

2

Adds the required unique configuration files to the /opt/cnsaroot/web/ks-repository/PXE_ID directory for the PXE installation specific to this request, including the ks.cfg, or Kickstart Configuration, file. Depending upon the operating system, other configuration files might be added to this directory, such as the boot.cfg file required for an ESXi installation.

For example, to create the customized ks.cfg file for the PXE installation,Cisco UCS Director takes the template ks.cfg file from the /opt/cnsaroot/templates/Operating_System/ directory and fills in the variables provided in the Setup PXE/vMedia Boot task. This customized ks.cfg file is saved in a directory that corresponds to the PXE ID, such as /opt/cnsaroot/web/ks-repository/PXE_ID.

3

Creates a file corresponding to the MAC address of the server in the /opt/cnsaroot/pxelinux.cfg/ directory in the Bare Metal Agent VM.

The workflow appends "01-" to the MAC address of the server to create the filename. This file includes information about where the image files are located and is generated through the pxe.cfg file in the /opt/cnsaroot/templates/Operating_System/ directory.


Note

Bare Metal Agent automatically creates Windows answer files for the supported operating systems. The same answer file is used for local boot and SAN boot. The Windows installation does not support multi-path SAN boot, but you can use a single path workflow to achieve SAN boot.

Determining the Windows OS Edition

The exact Windows OS edition is required for successful PXE boot of a Windows Server image. You must enter the exact character string used by Windows PE (WinPE). This string is case sensitive. The Windows OS edition follows a consistent naming convention. Some examples of OS editions are as follows: 

Windows Server 2008 R2 SERVERSTANDARD
Windows Server 2008 R2 SERVERSTANDARDCORE
Windows Server 2008 R2 SERVERENTERPRISE
Windows Server 2008 R2 SERVERENTERPRISECORE
Windows Server 2008 R2 SERVERDATACENTER
Windows Server 2008 R2 SERVERDATACENTERCORE
Windows Server 2008 R2 SERVERWEB
Windows Server 2008 R2 SERVERWEBCORE
Windows Server 2012 SERVERSTANDARD
Windows Server 2012 SERVERSTANDARDCORE
Windows Server 2012 R2 SERVERSTANDARD
Windows Server 2012 R2 SERVERSTANDARDCORE
Windows Server 2012 R2 SERVERDATACENTER
Windows Server 2012 R2 SERVERDATACENTERCORE

Procedure

Step 1

Navigate to the extracted ISO files for the Windows OS image.

Step 2

For a Windows 2012 R2 image, navigate to C:\win2k12r2\sources\install.wim and use a PowerShell cmdlet to find the edition.

An example of the use of this cmdlet is as follows: 

 
PS C:\Windows\system32> Get-WindowsImage -ImagePath 
C:\win2k12r2\sources\install.wim
Index       : 1
Name        : Windows Server 2012 R2 SERVERSTANDARDCORE
Description : Windows Server 2012 R2 SERVERSTANDARDCORE

Description : Windows Server 2012 R2 SERVERDATACENTERCORE
Size        : 6,653,031,430 bytes
<etcetera>

Step 3

For a Windows 2008 image, use the DISM.EXE syntax from the computer on which you installed the WAIK tools.

An example of the use of this syntax is as follows: 

 
C:\Program Files\Windows AIK\Tools\>dism 
/get-wiminfo /wimfile:e:\\Win2k8r2x64\sources\install.wim
Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Inputs for the Setup PXE/vMedia Boot Task

The following table describes the inputs for the Setup PXE/vMedia Boot task. Because the information for one or more of these inputs can be obtained from a previous task or from a user at run-time, the values for these inputs can be dynamic and change with each execution of the workflow.


Note

For legacy Setup PXE Boot tasks, the default Bare Metal Agent is the first Bare Metal Agent added. However, you can change the default Bare Metal Agent. See Changing the Default Bare Metal Agent Account.


Important

The host name specified in the Server Host Name field in the task input screen is correctly applied to the ESXi host after successful deployment of ESXi 8 or ESXi 9 OS in the following scenarios:

  • When Secure Boot is disabled, and the IP Configuration Type is Static or DHCP.

  • When Secure Boot is enabled, and the IP Configuration Type is Static.

In these cases, the configured host name is successfully passed to the ESXi host and is displayed when you log in to the ESXi host after deployment.

The host name specified in the Server Host Name field in the task input screen is not retained to the ESXi host after successful deployment of ESXi 8 or ESXi 9 OS when Secure Boot is enabled and DHCP is selected as the IP Configuration Type in the task input screen. To configure the host name for the ESXi host after a successful ESXi deployment, log in to the specific ESXi host console and execute the following commands:

Injecting Drivers When Installing RHEL 7 or CentOS 7 on UCS Modular Servers

When you install RHEL 7 or CentOS 7 on the UCS servers, manually inject drivers through the PXE.cfg file. The PXE.cfg file is available in the following location: /opt/cnsaroot/templates/(RHEL 7/CentOS 7 OS Catalog name).

The default PXE.cfg file contains the following line: 
append initrd=images/(RHEL 7/CentOS 7 OS Catalog name)/isolinux/initrd.img ramdisk_size=9216 noapic acpi=off ip=dhcp ks=$PXE_KS_URL 
ksdevice= inst.repo=http://$PXE_NATIVE_WEBSERVER/(RHEL 7/CentOS 7 OS Catalog name) net.ifnames=0 biosdevname=0

Note

Here RHEL 7/CentOS 7 OS Catalog name is the name of the OS image provided in the ISO extractor script while creating the RHEL 7 or CentOS 7 OS image template in Bare Metal Agent.

To inject the drivers, update the location of the drivers in the PXE.cfg file by updating the line as shown below: 
append initrd=images/(RHEL 7/CentOS 7 OS Catalog name)/isolinux/initrd.img ramdisk_size=9216 noapic acpi=off ip=dhcp ks=$PXE_KS_URL 
ksdevice= inst.repo=http://$PXE_NATIVE_WEBSERVER/(RHEL 7/CentOS 7 OS Catalog name) inst.dd=http://$PXE_NATIVE_WEBSERVER/ 
(RHEL 7/CentOS 7 OS Catalog name )/(name of the driver disk) net.ifnames=0 biosdevname=0

The driver disk should be in the ISO image format and placed in the following location: /opt/cnsa/images/(RHEL 7/CentOS 7 OS Catalog name)/


Note

  • Download the driver ISO image from the UCS Servers download page on the Cisco website.

  • The parameter inst.dd helps load the driver images during PXE install.

Simultaneous Provisioning of Windows Server Operating Systems

You can use Bare Metal Agent to run parallel workflows and simultaneously deploy Windows server images on multiple bare metal servers.

Prerequisites for Simultaneous Deployment

To ensure that you can perform simultaneous deployment of Windows Server operating system images, you must perform the appropriate configuration required for the versions of the operating system that are described in the following topics, including:

  • Adding the PowerShell packages to the WinPE.wim file

  • Updating startnet.cmd with the IP addresses and other information required for your environment

Bare Metal Workflows

You do not need to make any changes to your existing bare metal provisioning workflows to support simultaneous deployment of Windows server operating systems.

A PXE boot task in a workflow can only provision one server with a Windows operating system. You cannot use a single PXE boot task to provision multiple servers, but you can execute PXE boot tasks simultaneously multiple times.

Maximum Number of Simultaneous Deployments

The maximum number of simultaneous deployments is dependent upon the bandwidth of your TFTP and PXE networks.

Minimum Supported Level of Bare Metal Agent

Simultaneous deployment of Windows server operating systems requires a minium of Bare Metal Agent, Release 5.4. It is not supported in earlier releases of Bare Metal Agent.

Files and Folders Used In Simultaneous Deployment

The following files and folders are used during simultaneous deployment of Windows operating systems:

PXElinux.cfg File

The PXElinux.cfg file contains the MAC addresses for each of the servers and points to the WinPE.wim file.

Samba Folder

The /samba folder contains a folder for each of the following items. Additional information about the script and folder is provided below.

  • Windows images to be deployed on the bare metal servers

  • EnRoute.ps1 script

  • as-repository folder

AS-Repository Folder

The /samba/as-repository folder contains a folder for each MAC address of the servers for which a Windows operating is to be deployed. The PXE boot task creates and stores a separate Windows answer file for each of these servers in the appropriate MAC address folder. This folder might not be created until after the first PXE boot workflow is run.

EnRoute.ps1 Script

The EnRoute.ps1 script determines which Windows answer file in the as-repository folder belongs to the server that is being provisioned. If desired, you can customize this script. However, when you add the Bare Metal Agent to Cisco UCS Director, the script in the as-repository folder will revert to the default script without the customizations.

Windows Answer File

The Windows answer file contains settings and values that are used during the deployment of a Windows operating system. This answer file is typically named unattend.xml. During simultaneous deployment, a separate Windows answer file is created in each MAC address folder and then sent to the server to be used during the Windows operating system setup.

When the installation is successfully completed, the name of the answer file is changed to include "Completed."

For more information, see the Microsoft TechNet article on Understanding Answer Files.

Example: Simultaneous Deployment of Windows Server Operating Systems

This example describes what actions Bare Metal Agent performs when you execute two workflows at the same time, with each workflow designed to provision a bare metal server with a Windows operating system. The illustrations below describe how server 1 and server 2 are provisioned when the PXE tasks in the workflows are executed.

Figure 1. Server 1 Provisioning

Server 1 actions for simultaneous deployment of Windows operating systems

When the PXE boot task is executed in the workflow that provisions Server 1, the steps shown in the above illustration occur:

Step

Action

1

Server 1 boots up. The WinPE.wim file, together with its PowerShell packages and Startnet.cmd, is copied to the server.

2

The Startnet.cmd calls the EnRoute.ps1 script from the /samba folder on the Bare Metal Agent VM.

A folder is created under /samba/as-repository/ with MAC address of Server 1 as its name, for example, /samba/as-repository/MAC 1, and a Windows answer file is placed into that folder.

3

The EnRoute.ps1 script compares the MAC address on Server 1 with the MAC address folders available in the /samba/as-repository folder and finds the Windows answer file for Server 1 in the /samba/as-repository/MAC 1 folder.

4

Using the Windows answer file, the appropriate Windows operating system (shown as Windows installation files) is installed on Server 1.

When the installation is successfully completed, the name of the answer file is changed to include "Completed."

Figure 2. Server 2 Provisioning

Server 2 provisioning of Windows operating system

At the same time as Server 1 is being provisioned, when the PXE boot task is executed in the workflow that provisions Server 2, the steps shown in the above illustration occur:

Step

Action

5

Server 2 boots up. The WinPE.wim file, together with its PowerShell packages and Startnet.cmd, is copied to the server.

The Startnet.cmd calls the EnRoute.ps1 script from the /samba folder on the Bare Metal Agent VM.

A folder is created under /samba/as-repository/ with MAC address of Server 2 as its name, for example, /samba/as-repository/MAC 2, and a Windows answer file is placed into that folder.

6

The EnRoute.ps1 script compares the MAC address on Server 2 with the MAC address folders available in the /samba/as-repository folder and finds the Windows answer file for Server 2 in the /samba/as-repository/MAC 2 folder.

7

Using the Windows answer file, the appropriate Windows operating system (shown as Windows installation files) is installed on Server 2.

When the installation is successfully completed, the name of the answer file is changed to include "Completed."
